common bandwidth basis, and the most-often-used bandwidth is one cyc le. Units for W(f) are "vo lts squa red per cycle bandw idth," and considerable use has been made of the unit "volts per root-cy cle" for w(f). Now that "cycles" have become "hertz," this term is even more cumbersome, and is perhaps best replaced by "volts in a 1-hertz band." In order to convert to volts in a 1-hertz band, it is necessary to divide the voltage indication of the analyzer by the square root of the ana lysis bandw id th. For example, using the General Radio Ty pe 1900 Wave Ana lyzer, mu ltiply by the factors given in Table 3-3 to convert measured values of random noise t o vo lts in a 1-hertz band.

3.4.6 Spectrum of the Type 1383. The noise produced by the Type 1383 is w hite ove r a w ide rang e of frequenci es; the voltage spectru m is flat within ±1 dB for frequencies from 20Hz to 10 MH z, and w ithin ±1.5 dB for frequ encies from 10 to 20 MHz. A typical spectrum is shown in Figure 3-3. T he spectrum is cut off very sha rply at 20 MHz, so that the effective ban dw idth of the noise is quite closely 20 MH z. At the open-circui t output amp litude of 1 V, the voltage spe ctrum level is 224 J..l.V in a 1-H z bandwidth. 3.5 STATIONARITY.
4These numbers include the correction for the average-responding voltmeter in the 1900 Wave Analyzer.
In a constant-percent age-bandwidth analyzer, the ana lysis bandwidth is directly proportional to the center frequency of the pass band. This necessitates dividing the voltage indication by the square ro ot of the f requency as well as by the correction factor for the fractional bandwidth itself. When using constant-percentage-bandwidth analyzers, su ch as the General Radio T ype 1564 Sound and Vibration Analyzer or t he Type 1558 Octave-Band Analyzer, multiply the analyzer voltage indication by the appropri ate conversion factor in Table 3-4.
3-4 PROPERTIES OF RANDOM NOISE
A random noise is said to be stationa ry 5 if its various statist ical pa ra meters, such as the amp I itude distribution and the spectral intensity, do not cha nge w ith time. Random noise, of course, never repeats the same pattern from one moment to the next, but, if it is stationary , many measurements of the spectru m made at different times will all indi cate the same result, except for the unavoidable errors of measuring a random quantity in a finite time. In discussing t ests for stationarity, Bendat and Piersol 6 po int out th at, for most noise-generating 5sennett, op. cit., p. 52-54. 6sendat, J. S., and Piersol, A. G., Measurement and Analysis of Random Data, John Wil ey and Sons, Inc ., New York, 1966, pp. 219-223.
processes, it is su ffi cient to determine that the mean and the varian ce (square of the standa rd dev iation, a) do not change w ith the time at whi ch they are measured. Because the output of the 1383 is ac coupled, the mean is automatically zero, and it is only necessary t o observe the rms amp ! itude to prove stationa rity. This can be done by see ing that the flu ctuations in lo ng-time recordin gs of th e amplitude of the noise are no greater than the value predicted from t he bandwidth of the noise and the smoothing time of the detector. Th e importance of stati onarity in a rand om-n oise generator is analogous to stability in an osc illator; the user is assured that th ere is no change in the spectru m or the amplitude distributi on during the cou rse of an experim en t. The stat ionarity of t he noise output of the 1383 comes, f irst of all, from its noise sou rce; the temperature-limited thermionic diode has long been recog nized and used as a st andard noise sou rce f or noise-figure measu rements of high-frequency am p! ifi ers. 7 The noise current it produ ces is proportional t o the square root of 7spa ngenberg, K. R., Vacuum New Yo r k , 1948, p, 307,

the de plate current, which , in the 1383, is held constan t by feedback controll ing the f il ament current. Th e gain of the noise-cu rrent amp! ifi ers is stabil ized by feedback.
3.6 SUMMARY. Because vari ous terms used in speaking of rand om noise are sometimes con fused, a summary is presented here of th e most-often-used word s, together with a brief exp lanation of thei r mean ing: "N oise" is any unwanted signal. "Random noise" is a signa l whose future value cannot be exactly predicted and that does not contain any peri od ic componen ts. To different iate clea rly between the spectrum and the amp ! itude distribution, in this book the wo rd "densi ty" is used only in connection with the amp litude distribution. The word "intensity'' is used only in connecti on with the spectru m. " Gaussian" app lies on ly t o t he amplitude di stribution and ref ers to a pa rticular theoretical distribution. "White" refers only to the spectru m, and means that the spectral intensity is constant over some ran ge of interest.

5.1 GENERA L. With the instrument in position on the bench or installed in a relay rack, set the screwdriver-operated slide switch S502 (4, Figure 1-2) to the range corresponding to the power-line voltage. Connect the instrument to the line power, using the power ca ble supplied (P/N 4200-9622), and turn on the POWER switch. Follow the instructions given in paragraphs 5.2 and 5.3 for sett ing the OU TPUT LEVEL and METER FULL SCALE controls. 5.2 OUTPUT LEVEL CONT RO L. The OUTPUT LEVEL control is a con tinuous rotary control by means of wh ich the output level can be set at any selected value between its maximum open-circuit value and zero. The open-circuit output voltage is indi cated by the meter on the front panel, wh ich must be read on the scale appropriate to the setting of the output attenuator (the METER FULL SCALE control). 5.3 METER FULL SCALE CONT ROL.
coaxial system. Adaptors t o other types of high-frequency connectors are available (refer to Tabl e 1-4). The output connector can be moved to the rear panel if more convenient, as when the instrument is mounted in a relay rack (refer to paragraph 2.4 and Figure 8-2). 5.5 OUTPUT IMPEDANCE. The output impedance of the 1383 is 50 ohms, ±2%. The output can be sho rt ci rcuited without causing distortion of the output current. The maximum output current into a short circu it is 20 mA, rms, with occasional peaks that may exceed four times that value. 5.6 MODIFYING TH E OU TPUT. 5.6.1 Producing Lower Levels. GR874-G fixed coax ial attenuat ors (refer to Tabl e 1-4) in reducing the output level beyond the range of the 1383 output attenuator (the METER FULL SCALE control). These units are avai lable with attenuat ions of 3, 6, 10, 14, and 20 dB. They are designed for inserti on in a 50-ohm line.
The METER FULL SCALE control is the output attenuator and permits reduction of the output-voltage level by 80 dB from its maximum , in 10-dB steps. The voltage indicated is the open-ci rcuit output voltage; when the output is loaded by 50 n, the output voltage is reduced by half. Decibel readings on the dial of the METER FULL SCALE control can be added to the decibel indication of the meter to obtain the open-circuit output vo ltage in dec ibels below 1 V.
It may be necessary to restrict the bandwidth of the noise outpu t of the 1383. For inserting a tuned circuit or filter in series with the 50-ohm output, it may be convenient to use the GR874-X insertion unit, which permits totally-shielded connection of any circu it that will fit in its 2-inch long, 9/16inch-diamet er space.

6.1 GENERAL. The Type 1383 Random-Noise Generator is useful whereever a broad-band, high-level source of white noise is needed. Its 50-ohm output impedance and spectral intensity that is substantially constant to 20 MH z make it particularly useful at radio frequencies. For audio-frequency applications, Types 1381 and 1382 Random-Noise Generators 1 may be found to be more useful. They are intended for applications in the fields of acoustics, electroacoustics, psychoacoustics, and vibration analysis, in addition to their general use as audio-frequency generators of random electri ca l noise.
6.2 SIMULATION OF BACKGROUND NOISE. In studying the performance of radio, telemetry, radar or sonar systems with regard to their ability to transmit, detect, and recover signals in noise, it is convenient to simulate the real mixtu re of signal and naturally occurring noise by adding noise of controlled characteristics to a standard signal. Noise sometimes becomes the signal itself in tests of correlation receivers and other modern signal-processing systems.
' •
A mixture of signal and noise can be created by adding the output of a signal generator (possibly modulated in some appropriate m?nner) to the noise from the 1383. This can be accomplished with the GR874-TPD or GR874-TPDL Power Divider (see Table 1-4), with which signals in two 50-ohm systems can be added together. Noise that has been heterodyned to higher frequencies (see paragraph 5.6.4) can be used for this purpose.
6.3 MEASURING INTERMODULATION DISTORTION. Random noise is used in one very effective method of 2 measuring intermodulation distortion. White noise, which 1 Faran, J. J., Jr., " Random-Noise Generators" , General Radio

has been passed through a band-stop filter that reduces the level of the noise by, say, 80 dB over a narrow range of frequencies, is applied to the input of a system. Spectrum measurements of the system output indicate how much the "notch" in the noise spectrum has been filled in by intermodulation products. This is an especia lly significant measu rem-ent because white noise contains all the frequencies to which the system responds, and represents, in this sense, a "worst-case" type of test signal.
6.4 MEASURING CROSSTALK. White noise is a very appropriate signal for use in measuring crosstalk in multichannel telephone, radio, or telemetry systems. Spectrum analysis of the crossta lk signal identifies the frequencies that cause the greatest disturbance, thereby providing some assistance in determining the cause and specifying a cure.
6.5 MEASUREMENT OF EFFECTIVE BANDWIDTH. When wave analyzers or filters (or more complex systems) are used to measu re the spectral density of noise, it is necessary to know the effective bandwidth of the filter or of the system. The effective noise bandwidth can· be thought of in terms of an ideal filter having a rectangular frequency characteristic (constant over a range of freq uencies, and zero everywhere else). The effective noise bandwidth of a filter is the width of the pass band of the ideal filter whose output is exactly equal to the output of the actual filter when the inputs are the same white noise, provided the maximum transmissions of the two filters are the same. It can be measu red by finding the total signal transmitted when white noise of known spectral level is applied to the input. The frequency range of the white noise must include all frequencies for which the filter being measu red has appreciable transmission. When the effective bandwidth of the input noise is known, the necessary computations are simplified. Then the
APPLICATIONS 6-1
effective bandwidth of the filter is
where EBWn is the effective bandwidth of the noise; Nout is the output noise voltage; Nin is the input noise voltage; Gfmax is the maximum or peak gain of the filter (as measured with a sine-wave signal). The effective bandwidth of the noise output of the 1383 is very close to 20 MHz. In measuring the output voltage, it should be kept in mind that the voltmeter used should respond accurately to frequencies as high as 20 MHz and its operation (average, peak, or rms) should be known (refer to paragraph 3.3.3). The voltmeter should not be connected at the end of an unter minated cable, but should either terminate the cable (if a 50-ohm input adaptor is available) or should be bridged onto a terminated cab le.
6.6 NOISE TEMPERATURE. 6.6.1 Definition. It is somet imes convenient to express the noise level in a ci rcuit in terms of noise temperature. The noise voltage across a resistance due to thermal agitation of the free electrons in it (thermal noise) is
where en is the rms noise voltage, k isBoltzmann'sconstant(1.38X 10- 23 joules/°K), Tis the absolute temperature of the resistance in o K, R is the resistance in ohms, and B is the bandwidth in hertz in which the noise is bei ng observed. When an artificially-generated noise voltage, ea, is impressed across a resistance, it adds to the thermal noise whose amplitude is given above. It is then possible to define noise temperature as that temperature at which the thermal noise power would equal the total noise power 3 : (6-1) Because noise temperature depends upon the square of the noise voltage, such values can become extraordinarily large; for examp le, th e noise temperature of the output of the 1383 at full output is 1.8 X 10 13 o K. Noise temperature is most useful in describing the equivalent input 3More complicated (and more precise) definitions are given in "IR E Standards on Electron Tubes : Definitions of Terms, 1962 (62 IRE 7.S2)", Proc. IEEE 51, pp. 434-435 (March, 1 963) .
6-2 APPLICATIONS
noise of high-frequency receivers and amplifiers, where, incidentally, for certain types of circuits, the equivalent input noise temperature (see below) is considerably lower than the ambient temperature. The noise temperature of the output of the 1383 can never be less than its actual temperature, because its output circuits are comprised of real resistances. Fi[r ure 6-1 shows how the noise temperature of the output varies with the amount of attenuation when the OUTPUT LEVEL control is set so that the meter indicates full scale. Attenuation up to 80 dB is available with the METER FULL SCALE control ; additional attenuation must be obtained with external attenuators such as G R As is readily 874-G units (refer to parag raph 5.6.1 ). apparent, the noise temperature levels off at 290° K (23°C) as the attenuation is increased (assuming the noise generator and attenuators are at 23°C).
6.6.2 Measurement of Effective Input Noise Temperature. The effective input noise temperature of a receiver or amplifier is the temperature at which the resistive component of the input source would generate an amount of noise exactly equal to that arising in the receiver or amplifier only. One procedure for measuring the effective input noise temperature involves knowledge of the effective noise temperature of a sou rce under both hot (on ) and cold (off ) conditions. 4 For amplifiers intended for operation from a 50-ohm source, the effective noise temperature of the output of the 1383 wh en on can be read from Figure 6-1 or calculated from equation 6- 1, paragraph 6.6.1. The effective noise temperature when the noise generator is off is the temperature of the noise Normal room generator (and its output attenuators). temperature (290° K) is often a close-enough approximation. The measurement is made by connecting a noise generator to the receiver and measuring the output power wh en the noise generator is co ld off and hot on. The effective input noise temperature is then
where Tih is the noise temperature of the source when it is hot (on), Ti c is the noise temperature of the source when it is cold (off), Poh is the output power when the source is hot (on), and Poe is the output power when the source is co ld (off). 4for an excellent discussion of noise temperature and noisefigure measurements, refer to Mumford, W.W., and Sc heibe, E.H., Noise Perfonnance Factors in Communication Systems, Horizon House- Microwave, Inc., Dedham, M ass.

7.2 MINIMUM PERFORMANCE STANDARDS. 7.2.1 General. The two most important items to be measured in checking a noise generator for conformance to specifications are the spectrum and the amp I itude distribution. Both of these are com pi icated and tedious measurements, requiring a number of pieces of equipment. Instru ments have been constructed especially for this purpose at General Radio and are used in checking noise generators before they are shipped. The performance of this special ly constructed equipment is not readily duplicated by commercially available instruments. However, given below are lists of equipment and instructions for check ing these characteristics as well as possible, with readily available apparatus.
The spectrum of the noise output of the 1383 covers an extremely wide frequency range (20 Hz to 20 MHz). No single wave analyzer covers this range. Measurements, therefore, must be made with severa l analyzers that may operate in different ways, particularly with regard to bandwidth and detector characteri stics. Because of the difficulties of calibrating some of them, it is recommended that the analyzers be used to check the flatness of the spectrum, rather than to make abso lute determinations of the voltage spectrum level at each frequency. Spectrum.
A I ist of equipment that can be used to check the f latness of the spectrum of the 1383 is given in Table 7-1. Connect the output of the 1383 to the input of either the Rhode & Schwarz Type USVH Selective Microvoltmeter (Figure 7-1) or the Hewlett Packard Model 312A Wave

Record th e mete r indi ca ti ons as a function of frequency. This is the voltage spectru m level on an arb itrary sca le. T o measu re the spectrum at frequ encies below 20 kHz, use th e G R Type 1564 Sound and Vibration Analyzer connected as shown in Figure 7-3. Th e bandwidth of the noise shou ld be red uced before it is connected to the 1564. Th e simp le filter shown in Figure 7-4 can be constructed in a GR 874-X Inserti on Unit for this purpose. This fi Iter is designed f or operati on from a 50-ohm source into an open circui t (impedan ce high compared to 50 ohms). Place this filter at th e ou t put of th e 1383 and connect it to the inpu t of the 1564 by a shielded cab le. (Use an 874-02 Adapto r and a 1560-P95 Adaptor Cable. See Tabl e 1-4.) A measu rement made at 25 kHz (in th e 1/3octave band) corresponds to the level measured with th e high-frequency wave analyzer, and provides the tran sfer to a new arbitrary sca le f or thi s analyzer.

measurements made at lower frequencies must be mu ltiplied by the factor v'25000/f to find the voltage that would be measured by an· analyzer having constant bandwidth. The amount by which the resultant number differs f rom that measured at 25 kHz is the departure from perfect spectral f latness. 7.2.3 Amplitude Distribution. As mentioned above, special ly const ructed equ ipment is used at Gene ral Radio for check ing the amplitude distribution of noise generators before they leave the fa ctory. Customers fam i I iar with amp I itude distribution measurements may have suitab le equipment on hand, or at least wil l understand what so rt of equ ipment is necessary, and how to assemble it. Others must make use of comme rciall y available amplitude distribution analyzers, two of which will be discussed here. A list of equ ip ment tha t can be used in checking the amplitude density distribution is included in Table 7- 1. Sampling Unit Necessary. Regardless of what equ ipmen t is used fo r the measurement, there is one impo rtant co nsideration in connection with the 1383: The bandwidth of the noise produced by it is much too wide for any conventio nal amp li tude dist ri bution measu ring equipment. This problem can be overcome by us ing sampling tech niques to reduce th e bandwidth of the noise signal wh ile preserving the amplitude distribution chara cteristi cs. This is most eas il y done with a samp ling osci lloscope, which makes ava il ab le as an output the "sampled-and-he ld " wavef orm. One such is the Tek tronix 1S1 Sampl ing Plug-in Unit. It shou ld be triggered from an external source of pulses at, say, a 20-k Hz rate; the resulting rectangular samp led-and-held waveform is easily processed by amp litude distribution ana lyzers intended for audio-frequency use. An imp ortant precaut ion in the use of such a samp ling system is th at the " sampl ing efficiency'fnust be adjusted to unity. Otherwise the ho ld capac itor w ill not be cha rged fully to the va lue of th e no ise wavef or m at the sampling in stant, and the resulting output at each step will be some so rt of average over the prev ious few samp les; the ampl itude distribution of the samp led-and-held ou tput will not be representative of the no ise. The manufacturer's procedure shou ld be followed in setting th e samp ling efficiency to unity. When us ing the Tektronix 1S1, connect th e output of the 1383 by a 50-Q ca ble to the 50-Q input of th e sam piing unit. To avoid overload ing the sampl ing unit, adequate attenuation should be inse rted ahead of the sampler. This can be done co nven ientl y with th e output attenuator of the 1383. It may be necessary to use a buffer amp lifier at the output of the sampling unit, ahead of the amplitude distribution analyze r, either to in crease the signa l amplitude

R525 · Thi s potentiometer is adjusted to set th e voltage at the output of the regulated + 10 V supp ly. Connect a de vo lt mete r from AT531 (negative) to A T530 (posit ive ) and set R525 so th at th e voltmeter indicates 10 V. The negative 10-V supply is co ntrolled by the positive 10-V supply. If the negative supply is appreciably differen t from -10 V , measured from A T532 (negative) to AT531 (positive), R525 ca n be reset sl ightl y to average the two magn it udes about 10 V. R 143: This potentiometer set s th e magnitude of the de plate curren t in the noi se diod e, V901, and th ereby control s the magnitude of the noi se output of th e 1383. To set R 143, turn the OUTPUT LEVE L co ntrol on the front pane l fully clockwise and set th e potentiometer so that the meter indi ca tes full sca le. Then turn the OUTPUT LEVEL contro l co unter clockwi se, to redu ce the indi ca ti on of the meter by 1 dB. Reset R 143 to return the meter indi ca ti on to full sca le. This sets the noise leve l so that th ere is a reserve ampl itude of 1 dB beyond full sca le under normal con dition s.

1383 functioning properly, a 300-500 p.V signal will give a full-scale meter deflection over the entire 40-80 MH z range. A 500-p.V, 50-MHz signal from the generator should produce a 15 mV signa l at the output of the 40-80 MHz amp lifier (AT1 02). This input shou ld also produce a signal of approx imately 500 mV, 10 MHz at the OUTPUT terminals.

Rotary switch sections are shown as viewed from the panel end of the shaft. The first digit of the contact number refers to the section. The section nearest the panel is 1 , the next section back is 2, etc. The next two digits refer to the contact. Contact 01 is the first position clockwise from a strut screw (usually the screw above the locating key), and the other contacts are numbered sequentially (02 , 03, 04, etc), proceeding clockwise around the section. A suffix F or R indicates that the contact is on the front or rear of the section, respective! y .
