:DIFF:STATus?
Query Syntax
:DIFF{1:8}{A|C}:STATus?
Where the required specifier {1:8}{A|C} identifies the differential channel by its module slot and channel letter. For example, the differential waveform of channels 1A and 1B would be identified as :DIFF1A.
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 differential channel for use. A differential channel becomes available (AVA) when the following is true:
- An associated multi-channel module is installed or extended module is configured, and
- The differential channel is selected in the Channel Setup dialog (Use the
:DIFF:DMODecommand).
Available differential channels are shown in the Signals Palette. An available differential channel's waveform may or may not be displayed. A differential channel is unavailable (UNAV) if the differential channel is not selected in the Channel Setup dialog.
Use the :DIFF:DISPlay command query to determine if a channel waveform is displayed.
Example Command
:DIFF2A:STATus?
