Agilent Technologies 8164A, B Parameters None Response Identification terminated by END, Power-on

IEEE-Common Commands Instrument Setup and Status

command:	*IDN?
syntax:	*IDN?
description:	The IDeNtification query *IDN? gets the instrument identification over the interface.
parameters:	none
response:	The identification terminated by <END>:
	For example.
	Agilent Technologies	manufacturer
	mmmm	instrument model number (for example 8164B)
	ssssssss	serial number
	rrrrrrrrrr	firmware revision level
example:	*IDN? → Agilent Techologies,mmmm,ssssssss,rrrrrrrrrr<END>
N O T E	The Agilent 8163A, Agilent 8164A, and Agilent8166A will always return Agilent Technologies as the
	manufacturer. This will not be affected by the transition of these instruments to Agilent Technologies. This will
	allow programs that use this string to continue functioning.
	See “:SLOT[n]:HEAD[n]:IDN?” on page 82 for information on module identity strings.

command:	*OPC
syntax:	*OPC
description:	The instrument parses and executes all program message units in the input queue and
	sets the operation complete bit in the standard event status register (SESR). This com-
	mand can be used to avoid filling the input queue before the previous commands have fin-
	ished executing.
	Some module firmware includes commands that set a "StatNOPC" flag during execution
	to indicate that the module is busy. *OPC blocks the GPIB bus to all commands until every
	module hosted by the instrument is no longer busy.
	The following actions cancel the *OPC command (and put the instrument into Operation
	Complete, Command Idle State):
	•	Power-on
	• the Device Clear Active State is asserted on the interface.
	•	*CLS
	•	*RST
parameters:	none
response:	none
example:	*OPC
