:ALARm[1234]:SOURce (@<xt >) :ALARm[1234]:SOURce?

Assign the alarm number to report any alarm conditions on the specified channels. If not assigned, all alarms on all channels are reported on Alarm 1 by default.

The :SOUR? query returns a list of channel numbers in the SCPI

yz“z z” wxformat. The response begins with the “#” character, followed by a single character representing the number of succeeding characters to interpret as a length specifier, followed by a length specifier representing the number of bytes in the block, followed by a block of that many bytes. An empty scan list (one with no channels selected) will be “#13(@)”.

For example, if you send OUTP:ALARM1:SOUR (@101:103), the OUTP:ALARM1:SOUR? command will return the following:

#214(@101,102,103)
