*IDN?

Meaning and Type

Identification Query System Interface

Description

This query requests the power supply to identify itself. It returns a string composed of four fields separated by commas.

Query Syntax	*IDN?
Returned Parameters	<AARD>
	Field	Information
	Agilent Technologies	Manufacturer
	xxxxA	4-digit model number followed by a
		letter suffix
	nnnnA-nnnnn	10-character serial number or 0
	<R>.xx.xx	Revision levels of firmware
Example	Agilent Technologies,6681,0,A.00.01
Related Commands	(None)

*OPC

Meaning and Type

Operation Complete Device Status

Description

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

∙All 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, current or state, relays, and trigger actions are overlapped with subsequent commands sent to the power supply. The *OPC command provides notification that all overlapped commands have been completed.

∙Any change in the output level caused by previous commands has been completed (completion of settling time, relay bounce, etc.)

∙All triggered actions are completed

*OPC does not prevent processing of subsequent commands but Bit 0 will not be set until all pending operations are completed.
