Front Panel Rear Panel (Left side) Rear Panel (Right side) 9 VIT-700G User’s Guide 3.User’s Guide Summary This chapter introduces the VIT-700G VITS Inserters and explains where to find other information in this manual. Description of the VIT-700G The VIT-700G is a VITS (Vertical Interval Test Signal) Inserter operates in NTSC Composite or S-video mode. It inserts VITS of two standard types: FCC and NTC7 with the GCR test signal (Ghost Canceling Reference signal developed by Philips) on line 19. There are 3 VITS signal set in the VIT-700G; The two sets with the GCR signal are recommended for transmission applications while the NTC7 VITS without the GCR signal is primary use for signal routing applications. The purpose of a VITS inserter is to place standardized test signals in the vertical interval of a program source without disturbing the program itself. These test signals can then be used at a point further along in the video process to determine the characteristics of the transmission path. If, for instance, the VITS multiburst signal shows appreciable high-frequency roll off, it can be safely assumed that the program has lost some of the fine detail in the picture. The VIT-700G operates with either NTSC composite or S-video program signals. The output standard is always the same as the input standard. There are two Composite outputs, Output #1 is the bypass relay output and Output #2 is the non bypass relay output. When the power main is off, the input signal will automatically bypass to Output #1, and there will be no output on Output #2. Before You Start In addition to the VIT-700G itself, you should have the following items: • One power cord (Magni part # 340-1100-80) • Four (4) rubber feet (Magni part # 448-0003-00) • User’s Guide (Magni part # 946-2102-01, this manual) User’s Guide Overview • • • • • • • • • • • Chapter 1 provides the Conventions used and safety information. Chapter 2 shows the front picture and rear panel line drawing. Chapter 3 gives a brief description of the VIT-700G and a description of the manual. Chapter 4 is called Quick Start, and it’s for those people who want to get going in a hurry. Chapter 5 gives detailed installation instructions for rack mounting, electrical connections, and safety precautions. Chapter 6 gives complete operating instructions. Chapter 7 describes each of the test signals. Chapter 8 resolving problems, is the place to go if you run into trouble. Chapter 9 gives the detail technical specifications of the unit. Warranty Index 10 VIT-700G User’s Guide 4. Quick Start This chapter shows you how to quickly set up the VIT-700G and get VITS inserted on a program line. It is not a complete explanation. See Chapter 5 for more complete installation instructions and Chapter 6 for operations. Choosing Source Type If you are using an NTSC Composite system, be sure DIP switch 6 is down. If you are using the VIT-700G in a 525 S-video system, put DIP switch 6 up. Factory default is for NTSC Composite system. Connections The VITS Inserter is installed at some point in a video line carrying program material where the picture is verified to be correct. This is usually in the earlier stages rather than later. Connect the incoming program source to the VIT-700G Composite (or S-video) input. This input is terminated internally in 75Ω. Connect the Composite (or S-video) output from the VIT-700G to feed the next device in the video chain. The output standard is always the same as the input standard. There are two Composite outputs, Output #1 is the bypass relay output and Output #2 is the non bypass relay output. When the power main is off, the input signal will automatically bypass to Output #1, and there will be no output on Output #2. During normal operation, the two Composite outputs are identical. Selecting the VITS Set The active VITS set is chosen with DIP switch 8, 9, and 10. Only one of these switches should be up at any time. GCR signal is on line 19 of both fields, if selected. • • • To select FCC VITS with the GCR signal, put switch 10 up. To select NTC7 VITS with the GCR signal, put switch 9 up. To select NTC7 VITS without the GCR signal, put switch 8 up. Factory default setting The factory default settings are all DIP Switch settings in the down position. Refer to Table 1. The VIT-700G is operating in the following configuration: • Composite signal input • Normal operation mode; incoming program pass through • VITS added to program • VITS Set 1 is selected; FCC signals plus GCR signal • Remote control disabled 11 VIT-700G User’s Guide (This page intentionally leave blank) 12 VIT-700G User’s Guide 5. Installation This chapter gives complete installation instructions, including rack mounting, bench mounting, electrical and signal connections. CAUTION: Do not open the cover or bottom of the VIT-700G. There are potentially lethal voltages inside. Refer all repair problems to a qualified technician. Opening the VIT-700G and attempting to repair or adjust anything may void the warranty. Rack Mounting the VIT-700G You can install the VIT-700G in a standard electrical rack, 19 inches wide, by using the supplied four mounting screws. The VIT-700G occupies one unit (1¾") of vertical rack space. NOTE: Although the unit dissipates a maximum of 20 watts, for proper operation, adequate ventilation between the instruments installed in the rack must be observed. Figure 1 shows how to put the VIT-700G in a rack. Using the VIT-700G on a Bench The VIT-700G can be used from a table top or a work bench by attaching the four (4) rubber feet supplied with it. Stick them on the bottom at the four corners. You may want to remove the rack ears. They come off easily by removing four (4) screws on each side. 13 VIT-700G User’s Guide Connecting Power Connect the power cord from a live output to the power input on the rear panel. Turn on power to the VIT-700G with the switch on the rear panel. The Power light should be lit. Signal connections for NTSC Composite systems Figure 2 below shows the connectors to use when your system is NTSC composite. When you use the NTSC connections, DIP switch 6 should be off (down). Figure 2, Connections for NTSC Composite systems Signal connections for S-Video systems Figure 3 shows the connectors to use when your system is S-Video. When you use the S-Video connections, DIP switch 6 should be on (up). DIP switch 6 up S-Video output S-Video input for genlock Figure 3, Connections for 525 S-Video systems 14 VIT-700G User’s Guide Remote Selection The Remote connector on the rear panel can be used to remotely select the VITS set and other features. To make a selection, momentarily ground one of the pins in the Remote male 9-pin D connector to ground. For the Remote control to work, DIP switch 3 must be up.

Table I, DIP Switch settings in the rear panel NOTE: Factory default are all switches in the down position with FCC VITS selected. 15 VIT-700G User’s Guide (This page intentionally leave blank) 16 VIT-700G User’s Guide 6. Operating the VIT-700G This chapter contains complete operating instructions for the VIT-700G, including choosing NTSC Composite or S-video, selecting the VITS group, disabling VITS insertion, forcing color bars, and remote selection of signals. Selecting NTSC Composite or S-Video operation mode • • If you will use the VIT-700G in an NTSC system, use only the NTSC connectors, and put DIP switch 6 down. If you will use it in an S-video system, use only the S-video connectors, and put DIP switch 6 up. Lock Source The lock source, the incoming signal onto which the VITS will be inserted, will be either NTSC or S-video. Putting DIP switch 6 up (or grounding Remote pin 7) selects S-video. If the input signal is lost, there will be no output. Bypass relay output- Composite output only There are two Composite outputs; Output #1 is the bypass relay output and Output #2 is the non bypass relay output. When the power main is off, the input signal will automatically bypass to Output #1, and there will be no output on Output #2. During normal operation, the two Composite outputs are identical. Selecting VITS Sets There are three VITS sets available in the VIT-700G which are selected with DIP switches or by grounding the appropriate pin of the Remote connector. The following Table II shows all three sets and the signals that are in each. To select the VITS set with the DIP switches, DIP switch 3 must be down. DIP switches 10, 9, and 8 select VITS Sets 1, 2, and 3, respectively (see the table at the end of this chapter). Only one of these three switches should be up at a time. If more than one switch is up, the unit defaults to Set 1. To select the VITS set with the Remote connector pins, DIP switch 3 must be up. Pins 9, 4, and 8 select VITS Sets 1, 2, and 3, respectively (see Chapter 5). If more than one of these three pins is grounded at a time, the unit defaults to Set 1. VITS added to program mode To insert VITS to the incoming video, DIP switch 4 is down. In this mode, the VIT-700G is in line with the incoming program. This is a factory default mode. Video Pass mode To pass the incoming video without inserting VITS, put DIP switch 4 up, or ground Remote pin 6. In this mode, the VIT-700G is transparent to the incoming program. 17 VIT-700G User’s Guide Normal operation mode This mode will allow the incoming program to pass-through to the output with or without VITS insertion. VITS insertion is depending on other DIP switch setting. Refer to Video Pass mode. Forcing Color Bars mode To force FCC Color Bars on all active lines, put DIP switch 7 up, or ground Remote pin 3. This mode is useful to check continuity of a system when there is no program material coming into the unit. Warning: Forcing FCC Color Bars will replace all incoming program material with full field color bars. This would be a dangerous practice during live programming.

Use of Test Signals Each test signal was designed to measure one or more parameters of a video or transmission system. This chapter describes each of the test signals found in the VIT-700G and its primary uses. (Note: All of the waveforms and vector displays in this section were obtained by captured the waveforms on a Magni AVM-510A waveform monitor.) FCC Test Signals (VITS Set 1) Three standard FCC test signals are supplied with the VIT-700G. Namely; FCC Composite signal on line 18 of both fields, FCC Combination signal on line 17 of Field 1 and Color Bars signal on line 17 of Field 2 FCC Color Bars (Line 17/F2) This full field color bar signal has eight bars: white, yellow, cyan, green, magenta, red, blue and black. The white bar is 100% white; the black bar is 7.5 IRE for setup. This signal is used for monitor setup and to verify luminance and chrominance amplitudes in a system. With the baseline of the signal on the zero IRE graticule, the white bar should reach the 100 IRE line, and the black bar should rest at 7.5 IRE. The tops of the first two color bars, yellow and cyan, should be even with each other and with the 100 IRE line. The bottom edges of the last color bars, red and blue, should be even with each other. Figure 5 --- FCC Color Bars FCC Multiburst (Line 17/F1) This signal gives an indication of the luminance bandpass of a system. The beginning of the signal has a 100 IRE white bar for reference. The frequency packets are on a 40 IRE pedestal with an envelope of 60 IRE p-p, reach from 10 to 70 IRE. The frequencies are 0.5, 1.25, 2, 3, 3.58 and 4.1 MHZ. 19 VIT-700G User’s Guide Figure 6 ---FCC Multiburst FCC Composite (Line 18/F1&F2) This signal is comprised of several different parts. • Modulated 5-step has five equal luminance steps starting at zero and ending at 80 IRE. This assures that the modulation of the last step does not exceed 100 IRE. It is used to measure differential phase and gain. • The 2T pulse is 250 ns wide at its half-amplitude point. Ideally the pulse should reach the 100 IRE line without ringing on its baseline. • The modulated 12.5T pulse is used to measure chrominance gain and delay inequalities. • The white bar has a risetime of 250 ns. The top of the bar should not tilt, and there should be no ringing evident immediately before and after the transitions. The 2T pulse can be compared against this bar, if the overall amplitude of the system does not produce 100 IRE of luminance content. Figure 7--- FCC Composite signal NTC7 Test Signals (VITS Sets 2 &3) There are two NTC7 signals primarily for studio routing applications. Namely, the NTC7 Composite signal on Line 17 of Field 1 and NTC7 Combination signal on Line 17 of Field 2. NTC7 Composite (Line 17/F1) This signal is very much like FCC Composite with the parts in a different order. • • • • The white bar is 100 IRE high and has a risetime of 140 ns. It should not tilt, and there should be no ringing before or after the transitions. It is also used as a reference for comparing the 2T pulse. The 2T pulse should reach to 100 IRE. It should not have any ringing at its base. The 12.5T modulated pulse is used to measure chrominance gain and delay inequalities. The modulated 5-step has five equal luminance steps from zero to 90 IRE, so the top of the modulation reaches 110 IRE. It is used to measure differential phase and gain. Figure 8 --- NTC7 Composite signal 20 VIT-700G User’s Guide NTC7 Combination (Line 17/F2) This signal consists of a multiburst and a 3-steps modulated pedestal (Pink Panther signal). • The multiburst begins with a 100 IRE white bar for reference. The frequency packets are 50 IRE p-p on a 50 IRE pedestal. They should reach from 25 to 75 IRE. The frequencies are 0.5, 1, 2, 3, 3.58, and 4.2 MHZ. • The modulated pedestal carries a chrominance signal at 90 degrees and three different amplitudes: 20, 40 and 80 IRE p-p. Figure 9 --- NTC7 Combination signal Ghost Canceling Reference (Line 19/F1&F2 on VITS sets 1&2) The GCR (Ghost Canceling Reference) signal is used in a system developed by Philips to reduce or eliminate ghosts in transmission paths. Ghosting is caused by multi-path reception of over-the-air signals. There are two phases of the signal, which are put in separate fields in a repeating pattern. The repeat pattern is longer than the four fields of 525/ Systems M NTSC color television system. The pattern resembles a frequency sweep and can be used as an indication of frequency response. It is a synthesized signal to have a flat frequency spectrum to 4.2MHz (Similar to the frequency response of a SINX/X time domain signal). A program with a GCR signal together with a GCR corrector in a receiver greatly improves television reception for many viewers plagued with signal ghosting. Figure 10 --- Ghost Canceling Reference Signal 21 VIT-700G User’s Guide 8. Resolving Problems This chapter contains a list of suggestions for resolving possible problems encountered with the installation and operation of the VIT-700G. CAUTION: Do not remove the cover from the VIT-700G. Doing so may void the warranty. The VIT-700G contains no user-serviceable parts. Refer all internal servicing to qualified personnel. · Front panel lights do not light See that the unit is plugged in. Check the power outlet used by the VIT-700G by trying something else in that socket. Try a different power cord. Check the fuse. · No signal from VIT-700G If there is a front panel light on, then check the connections from the program source to the picture monitor or waveform monitor. If the signal is routed through a routing switcher or patch panel, make a temporary connection from the program source directly to a picture or waveform monitor. · Signal is weak, too small This is often caused by double termination of the signal line. All video lines should be terminated once with 75Ω. If the test signal is looped through several pieces of equipment, check to see that only the last device in the chain has a 75Ω termination. Double termination results in a signal that is 66% of normal amplitude. If the signal is only slightly below 100%, it may be caused by excessively long coax lines, or, more likely, by a terminator that is slightly below 75Ω. For accurate testing, use external terminators of 0.1% tolerance wherever possible. · Signal too strong This is often caused by no termination. All video lines should be terminated once with 75S. The last device in a chain of loop-thru connections should have a 75Ω termination. This terminator is sometimes external and sometimes internal. If the signal is only slightly above 100%, it may be caused by a terminator that is slightly above 75Ω. For accurate testing, use external terminators of 0.1% tolerance wherever possible. · Signal is erratic 22 VIT-700G User’s Guide A signal that jumps in amplitude erratically is most often caused by a weak or broken connection. Try different coax cables. Check for loose BNC or S-video connectors or terminators. · VIT-700G won’t genlock Check DIP switch 6. It should be up for S-Video inputs and down for NTSC composite inputs. Check the input signal with a waveform monitor. The VIT-700G will not lock to signals that are not time-base corrected.
