SCPI Commands for Digital Interfaces
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 155 for details.)
Command: *STB?
SCPI equivalent:
STATus:SBYTe[:EVENt]?
Power-on Status Clear
The Power-On Status Clear command controls the automatic power-on clearing of
the Service Request Enable Register, the Standard Event Status Enable Register, the
Parallel Poll Enable Register and the Error/Event Queue.
Command: *PSC {0|1}, *PSC?
SCPI equivalent for multichannel use:
SYSTem[<channel>]:POSClear {ON|OFF|0|1}
SYSTem[<channel>]:POSClear?
Individual Status Query
The individual status query allows the programmer to read the state of the IEEE
488.1 ist (individual status) message without performing a parallel poll. The query
returns a "1" or "0."
The ist message is formed by ANDing the bits in the Parallel Poll Enable Register
(*PRE) with the Status Byte and then ORing the result. In other words, the ist is
TRUE if any of bits of the Parallel Poll Enable Register AND'ed with the Status Byte
are TRUE.
Command: *IST?
Operation Complete
The Operation Complete command causes the power supply to generate the
operation complete message in the Standard Event Status Register when all pending
operations have been finished.
Command: *OPC, *OPC?
