## Query Syntax

    :CMODeN:STATus?

Where N identifies a specific common-mode 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 common-mode waveform 3 (from the pairing of channels 3 and 4) is `CMODe5_3`.

## Query Response

    {AVA | UNAV}

## Description

Queries the availability of a common-mode waveform for use. A common-mode waveform becomes available (`AVA`) when the following is true:

- An associated multi-channel instrument is installed or connection is configured, and
- The common-mode channel is selected in the Channel Setup dialog box.

Available common-mode channels are shown in the Signals Palette. An available common-mode channel's waveform may or may not be displayed. A common-mode channel is unavailable (`UNAV`) if the common-mode channel is not selected in the Channel Setup dialog box.

Use the `:CMODe:DISPlay` command query to determine if a channel waveform is displayed.
