:CMODe EYE Commands

Command Syntax

:CMODeN:EYE:WINDow:WIDTh<percent>

Where N identifies a specific common-mode waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 common-mode waveform 3 (from the pairing of channels 3 and 4) is CMODe5_3.

<percent> is a double.

Description

MEASUREMENTS AFFECTED

Infiniium uses the eye boundaries during these measurements:

  • Eye Amplitude
  • Crossing %
  • Duty-Cycle Distortion
  • Eye Height
  • Signal to Noise Ratio
  • One Level
  • Zero Level

When the "At Clock Time" eye window determination method is selected (see :CMODe:EYE:WINDow:METHod), this command specifies the UI percentage width about the recovered clock location to use as the eye window. A zero percent for this setting means only the recovered clock location is used.

This command is equivalent to the settings in the Eye tab of the Configure Measurements dialog box.
