Query Syntax

:DIFFN:SNOise:SNValue:LEVel{0:3}?

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.

Description

This query returns the calibrated oscilloscope noise value at the specified level.

AN NRZ signal has LEVel0 and LEVel1. A PAM3 signal has LEVEL0, LEVel1, and LEVel2. A PAM4 signal has LEVEL0, LEVel1, LEVel2, and LEVel3.

Use the :DIFF:SNOise:CALibrate command to start the oscilloscope noise calibration.
