GSM standard 11.10 prescribes a number of tests requiring measurements on mobile stations under multichannel conditions (fading). The combination of Radiocommunication Tester CRTP02 or CRTC02 and Signal Generator SMIQ allows cost-effective performance of the most important fading tests, in particular the tests according to sections 13.2, 14.2 and 14.3 of GSM 11.10. The aim of this application note is to familiarize the user with all the capabilities offered by the above combination of measuring instruments. The user should then be able to quickly generate and run his own fading tests using the IEC/IEEE-bus control commands described in this application note. To facilitate reading of the following, the testers CRTP02 and CRTC02 are referred to as CRTx.

As the data rates in high-speed digital designs increase, the limits for overall system jitter become tighter. This especially applies to the various components of the clock tree, where the jitter limits for reference clocks, clock buffers and jitter attenuators are even tighter. Due to their high phase noise sensitivity, phase noise analyzers are the instruments of choice for these tests.

While Mobile phones are allowed to require approximately 3 time slots for switching from transmission to reception, base stations must be able to transmit and receive at a new frequency in every time slot in the frequency hopping mode. This behaviour must of course be tested and measurements carried out on the base station transmitter and receiver. Since there is no signal generator which is able to settle at different frequencies from one to the next time slot with GSM modulation, a solution to this problem was found by linking two Signal Generators SME in such a way that they alternately provide signals at different frequencies.
