Features X RF Rx part of W-CDMA UE can be evaluated by BER/BLER. X BER can be measured with/without Error correcting function. X Demodulation data(Data,Clock,Enable,Error) is outputted from the rear of MS860xA. (The development of data logging and analyzing application is being considered.)

Decode ON/OFF function Minute error status can be observed by eliminating error correcting function in Decode OFF. (Error correcting function is capable of correcting errors of max.1.0 x E-3(approx.). If error correcting function is ON, it is unable to identify the generation of error less than 1.0 x E-3.)

Reference frequency generation : required when the reference crystal accuracy inside Rx module is low. (Normally the crystal accuracy within Rx module is low because reference frequency is provided by BB part.) Output control : required when module output is out of Tx tester’s input range, 0.1Vp-p to 1.0Vp-p.

Merits of Real-time BER • Estimation of BER by NF and EVM, etc. Merit
Real-time BER
Accuracy in meas. result allows for deteriorating the performance to the threshold of required level. As a result, cheaper components can be adopted .
Cost reduced
• Measurement of BER X Measured by the BB Rx part of conventional model. Merit
Error correct OFF function enables to observe minute errors less than 1.0 x E-3, thus, more reliable quality assurance is achieved.
Real-time BER More reliable quality assurance
Real-time BER X Measured by the BB Rx part of newly-developed model. Developed at its Not affected by the development status Merit of BB Rx part. own pace Able to identify in which bugs are caused, Easy to perform Merit RF Rx part or BB Rx part. fault isolation Real-time BER X Measured by simulation with a PC.
