:DIFF SNDR Setup Commands

Command Syntax

:DIFFN:SNDRatio:LFPLength <number_of_UIs>

<number_of_UIs> 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.

:DIFFN:SNDRatio:LFPLength?

Description

This parameter is used in the filter to compute the linear fit pulse response. It is the length of the pulse fit, expressed as the number of unit intervals (UIs). It is sometimes denoted using Np.

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