Operation Status Register Summary (OSR)
This bit is TRUE when a bit in the Operation Event Status Register is set
and its corresponding bit in the Operation Status Enable Register is set.
Service Request Enable Register
The Service Request Enable Register allows you to select the
reasons for the power supply to issue a service request. The Service
Request Enable Register allows you to select which summary
messages in the Status Byte Register may cause service requests.
To clear the Service Request Enable Register send *SRE 0 . A
cleared register does not allow status information to generate a
service request.
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 5-32 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 5-32 for details.)
Command:
*STB?
SCPI equivalent:
[:]STATus[<address>] :SBYTe[:EVENt] ?
