## Command Syntax

    :DIFFN:SNDRatio:SAVE:FILE "filename"

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:SAVE:FILE?

## Query Response

    "string"

## Description

When `AUTomatic` is selected as the SNDR standard (see `:DIFF:SNDRatio:STANdard`) and saving the automatic calculations to a standards file is turned on (see `:DIFF:SNDRatio:SAVE`), this command specifies the name of the SNDR standard definition file.

The saved file includes comments that indicate valid values for each element and their effects.

The saved standard definition file can be used again when `FILE` is selected as the SNDR standard (see `:DIFF:SNDRatio:STANdard`).
