Nadc: Power Meter Presets; A Trace Display Of The Active Timeslots - Agilent Technologies EPM-P Series Programming Manual

NADC
The NADC set-up provides:
•
•
The measurement is started by detecting the RF burst—for example the
burst emitted by a mobile—using the internal RF level trigger. The
internal level trigger is set to –20dBm. Time-gating is used to measure the
average power in two active timeslots which are separated by two inactive
timeslots
The following table shows the power meter presets when
<character_data> is set to NADC. Commands not listed are preset
according to their DEFault values (for further information refer to Table
11-1):

Average power measurement of both active timeslots in NADC or
IS-136 "full rate" transmission. This assumes that there are two
timeslots to be measured in each frame as for example with
timeslots 0 in the following diagram:
