12 SYSTem Subsystem
GSM900
Table 12-2
GSM900.
The GSM900 set-up provides the following:
– Average power measurement in one GSM timeslot
– Trace display showing "on" timeslot
A GSM900 measurement is started by detecting the rising edge of a GSM RF
burst—for example the burst emitted by a GSM mobile—using the internal RF level
trigger. The trigger level is set to –20 dBm. Time-gating is used to measure the
average power in the useful part of a GSM burst.
Commands not listed are preset according to their DEFault values (for further
