Making EDGE (with GSM) Measurements
Making the Power vs. Time Measurement
Making the Measurement
NOTE The factory default settings provide a EDGE (with GSM) compliant
measurement. For special requirements, you may need to change some
of the settings. Press
Meas Setup, More (1 of 2), Restore Meas Defaults at
any time to return all parameters for the current measurement to their
default settings.
Select the desired ARFCN, center frequency, timeslot, burst type, and
TSC (Training Sequence Code) as described in the section titled
“Changing the Frequency Channel” on page 24.
Timeslot is available when Burst Sync is either Training Sequence or
RF Amptd.
The timeslots are determined by taking the acquired data and dividing
it into timeslots 0 to 7. An active timeslot burst must be within
approximately 25% of the expected timeslot position, otherwise the
E4406A may think the burst is an adjacent timeslot and may not detect
it. The trigger delay can be used to position the signal if it is not
aligning in the timeslots as desired.
Press
Measure, Pwr vs Time to immediately make Power vs. Time the
active measurement.
To change any of the measurement parameters from the factory default
values, refer to the “Changing the Measurement Setup” section for this
measurement.
