:CHANnel:STATus?
Query Syntax
:CHANnel{1:8}{A|B|C|D}:STATus?
Where the required specifier {1:8}{A|B|C|D} identifies a channel by its module slot number and channel letter. For example, channel 3C (CHANnel3C).
The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.
Query Response
{AVA | UNAV}
Description
Queries the availability of a channel for use. A channel becomes available (AVA) when an associated module is installed or extended module is configured. Available channels are shown in the Signals Palette. An available channel's waveform may or may not be displayed. A channel is unavailable (UNAV) if no channel hardware or extended module hardware is installed.
Use the :CHANnel:DISPlay command query to determine if a channel waveform is displayed.
