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 ANDed 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?
Wait-to-Continue Command
The Wait-to-Continue command prevents the power supply from executing any
further commands or queries until the no-operation-pending flag is TRUE.
Command:
*WAI
