CMD 59 Digital Radiocommunication Tester
The CMD 59 Digital Radiocommunication Tester is a compact unit for testing PCS (PCS 1900) base stations (BTS) and BTS modules. It allows measurements on base station transmitters and receivers without affecting calls in progress. With the in-service test option, measurements can be made without taking a cell site out of service.
Detailed PCS Knowledge Not Required
The CMD 59 is easy to use and is equally at home in production, installation, and service environments. Ease of use goes beyond the front panel. All parameters can be individually modified in the configuration menus to allow easy adaptation to stringent user-specific tolerances. Any parameters that have modified with respect to the default standard specifications are clearly shown on the display.
Additional attenuators, cables, and amplifiers are often required for connecting to the BTS. The effect of these additions are taken into account by the CMD 59 when calculating the measurement results.
Test Your Transmitter ...
The following PCS-specific measurements are available for transmitter testing:
Mean RF carrier power
Power ramping
Phase/frequency error
Spectrum due to modulation
Spectrum due to switching
Measurement results on the transmitter's traffic channel (TCH) are obtained by simply switching to the corresponding menu. The results are graphically displayed along with applicable statistical functions.
... And Receivers Too!
You can also make the required tests on receivers:
Bit error rate (BER)
Adjacent time slot rejection
Plus Many Other Measurements
You can also make may other base station measurements with the CMD 59 including:
Echo test
Module tests without signalling or time synchronization
Alignment using built-in multifunction RF generator
AF measurements with optional frequency counter
