Phase Error vs Time Display

The Phase Error vs. Time display shows the phase angle of the symbol error over time. The phase is
plotted along the vertical axis while time is plotted along the horizontal axis.
NOTE. A maximum of approximately 80,000 samples can be analyzed by the General Purpose Digital
Modulation measurements (the actual value varies with modulation type).

Description
Specifies the type of modulation used for the input signal and other parameters.
Specifies settings for frequency error, measurement BW and Frequency Deviation. Each
of these settings is set internally when set to Auto. Alternatively, you can specify values
appropriate for specific measurement needs.
Enable the Equalizer and adjust its parameters.
Specifies additional parameters.
Used to set parameters for finding a burst within the data record and for entering a
Synch word.
Contains parameters that define the portion of the acquisition record that is used for
analysis. Also allows you to specify the Units (Seconds or Symbols) for the GP Digital
Modulation displays.
Allows you to set the trace display characteristics.
Specifies the horizontal and vertical scale settings.
Enables you to set characteristics of the measurement display.
