Adjacent Channel Power
Displaying Accurate Peak Power (Recommended for Pulsed
Signals)
For pulsed signals, you can get a more accurate measurement of the signal’s peak or
average power by using the Peak Power Detector setting (see below) in the test set.
The test set measures average power of signals by default. For
non-constant-duty-cycle signals such as GSM, an average power reading fails to
accurately show amplitude when the signal is
On if other timeslots in the frame are
powered
Off.
If the [Power Detector] menu key is grayed out, the test set needs to be upgraded in
order to measure pulsed signals. Contact the Agilent Service Center for upgrade
information.
If it is not a peak signal, it is probably better to select
Average for a more accurate
result.
To Display Peak Power:
Setting the Control Units
In some instances you may be provided specifications by engineering in either dBm
or watts. You can switch between the two units in order to make it easier to interpret
measurement results.
