*ESR?

This query reads the Standard Event Status Event register. Reading the register clears it. The bit configuration of this register is the same as the Standard Event Status Enable register (see *ESE). See Chapter 4 under “Programming the Status Registers” for a detailed explanation of this register.

Query Syntax

*ESE?

Parameters

None

Returned Parameters

<NR1> (register value)

Related Commands

*CLS *ESE *ESE? *OPC

*IDN?

This query requests the ac source to identify itself. It returns the data in four fields separated by commas.

*OPC

This command causes the interface to set the OPC bit (bit 0) of the Standard Event Status register when the has completed all pending operations. (see *ESE for the bit configuration of the Standard Event Status registers.) Pending operations are complete when:

υall commands sent before *OPC have been executed. This includes overlapped commands. Most commands are sequential and are completed before the next command is executed. Overlapped commands are executed in parallel with other commands. Commands that affect output voltage or state, relays, and trigger actions are overlapped with subsequent commands sent to the ac source. The *OPC command provides notification that all overlapped commands have been completed.

υall triggered actions are completed and the trigger system returns to the Idle state.

*OPC does not prevent processing of subsequent commands but Bit 0 will not be set until all pending operations are completed. The query causes the interface to place an ASCII "1" in the Output Queue when all pending operations are completed.
