:DIFF:SNDRatio:PUINterval

:DIFF SNDR Setup Commands

Command Syntax

:DIFFN:SNDRatio:PUINterval <points_per_UI>

<points_per_UI> is an integer.

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.

Query Syntax

:DIFFN:SNDRatio:PUINterval?

Description

Specifies the number of sample points per UI (symbol) to use in the SNDR computation.

Technology standard test documents typically tell you the value expected to be used for this parameter.
