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
