Remote Operation

For example:
Sending
*SRE 8
sets bit 3 of the Service Request Enable Register. This
will cause the Summary bit of the Questionable Status register (bit 3) in
the Status Byte to generate a service request message whenever it gets set.
(See “Status Byte” on page 5–26 for details.)
Command:
*SRE <Service-Request-Enable>, *SRE?
The SCPI equivalent for multichannel use:
[:]STATus[<channel>]:SREQuest:ENABle <status-enable>
[:]STATus[<channel>]:SREQuest:ENABle?
Query the Status Byte
The status byte query will return the contents of the status byte register
and the MSS (Master Summary Status) message. The response is in the
format of a weighted decimal value representing the status byte register
and the MSS message (bit 6). Thus, the response to
*STB?
is identical to
the response to a serial poll except that the MSS message appears in bit 5
in place of the RQS message. (See “Status Byte” on page 5–26 for
details.)
Command:
*STB?
SCPI equivalent:
[:]STATus
[<address>]:SBYTe[:EVENt]?
