Basic Discrete PAvT

This measurement returns the amplitude, phase and frequency errors of each step. For the first step,

frequency errors are referenced to the frequency set for the acquisition, and phase is taken as zero. The

amplitude, frequency and phase errors of the remaining steps are referenced to the first step. Because

Basic Discrete PAvT needs to set the channel filter, it is exclusive with other measurements; once Basic

Discrete PAvT measurement is selected for one analysis of this acquisition, only Basic Discrete PAvT is

allowed for all analyses of this acquisition.

To set up a basic discrete PAvT measurement in the List Sequencer for a GSM signal from the front panel

do the following:

Step 1. Set the test set to the Sequence Analyzer mode:

Press

Mode, Sequence Analyzer, Mode Preset.

Step 2. Set up the GSM/EDGE Basic Discrete PAvT parameters:

Press

Meas Setup, Basic Meas Setup, Basic Frequency Error Setup.

Change the

Info BW as required.

Step 3. Set up an Acquisition in the test set. To do this see “Front Panel List Sequencer Setup” on

page 78)
