CMD 80 Digital Radiocommunication Tester User Manual
With the Analog mode option installed, the tester supports testing of analog
radiotelephones or test the analog operation of dual-mode radiotelephones
(CDMA/Analog Mode handsets). The analog tests are AMPs based.
The tester can measure the following key analog parameters:
H
SINAD
H
Frequency and deviation (SAT) frequency error
H
RF power
H
Distortion
H
Hum and noise
H
Frequency response
H
Modulation limits
With the TDMA mode option installed, the tester supports testing of TDMA
(Time Domain Multiple Access) radiotelephones. The tester TDMA tests are
based on the IS-136-A and IS-137-A standards.
The tester can measure the following key TDMA parameters:
H
BER for receiver testing
H
Error vector magnitude
H
Phase error
H
Magnitude error
H
Adjacent channel power
H
Power versus time (RF power transition time)
H
Time alignment
H
Carrier frequency error
H
Frequency accuracy
H
Power measurements mobile and base station
