Description

To View the Histograms

Viewing the histograms allows you to see the affects of your adjustments in real time.

  1. Turn on the TDECQ measurement.
  2. In the Results panel, select Annotations.

Sets the time spacing in UI between the left and the right measurement histogram windows for a :MEASure:EYE:TDECQ measurement. Before you can position the histograms, you must turn histogram time optimization on with the :MEASure:TDEQ:OHTime command. To adjust the adjustment limit in UI between, use the :MEASure:TDEQ:OHTLimit command.

This command is equivalent to the Histogram Spacing setting which is located in the TDECQ Configuration tab of the PAM-N Analysis Setup dialog. To watch how the histogram changes while you adjust this setting, display the histograms on the waveform.

The :MEASure:TDEQ:OHSeparation command should always be followed with a *OPC? query for program timing.
