:DIFF CRECovery Commands

Command Syntax

:DIFFN:CRECovery:ECLock:ALIGn {CALigned | EALigned}

Where N identifies a specific differential 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 differential waveform 3 (from the pairing of channels 3 and 4) is DIFF5_3.

:DIFFN:CRECovery:ECLock:ALIGn?

Description

When an Explicit clock recovery method is selected (see :DIFF:CRECovery:MODE), this command specifies the clock/data alignment:

  • CALigned — Center Alignedwith data. Normally, the clock is referenced to the center of the data eye. When the clock edge occurs, data is sampled to determine its logical value. This is the default setting.

  • EALigned — Edge Aligned with data. In some unusual cases, the clock edges and data edges may occur in phase. The clock edges occur about the same time as the data edges.

See the user's guide for more information about the Clock/Data Alignment option.
