## Command Syntax

    :DIFFN:TTCHannels {{OFF | 0} | {ON | 1}}

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:TTCHannels?

## Query Response

    {0 | 1}

## Description

This command enables or disables the vertical scale Tie to Channels option.

When ON, the vertical scale of the differential and common-mode signals are based on the vertical scales of the channels that are combined to form the signal and cannot be changed.

When OFF, you are able to adjust the vertical scale of the differential and common-mode signals independently.

You can use the `:DIFF:DAVertical` command to automatically set the vertical scales.
