IEEE 488.2 Common Commands

	The following table lists the IEEE 488.2 Common (*) Commands that can
	be executed by the Microwave Switch modules. The operation of some of
	these commands is described in Chapter 3 of this manual. For more
	information on Common Commands, refer to the HP 75000 Series B
	Mainframe User’s Manual (HP Model Number E1300/E1301), appropriate
	HP Command Module User’s Manual, or the ANSI/IEEE Standard
	488.2-1987.
Command	Title	Description
*IDN?	Identification query	Returns identification string of the switchbox.
*RST	Reset	Opens all channels, and invalidates current channel list for scanning.
		Sets ARM:COUN 1, TRIG:SOUR IMM, and INIT:CONT OFF.
*TST?	Self-Test	Always returns 0.
*OPC	Operation Complete	Sets the request for OPC flag when all pending operations have
		completed. Also sets OPC bit in the Standard Event Register.
*OPC?	Operation Complete Query	Returns a 1 to the output queue when all pending operations have
		completed. Used to synchronize between multiple instruments.
*WAI	Wait to Complete	Halts execution of commands and queries until the "No Operation
		Pending" message is true.
*CLS	Clear status	Clears all Event Registers, the Request for OPC flag, and all queues
		(except output queue).
*ESE<mask>	Event status enable	Used to set the bits in the Event Status Enable Register.
*ESE?	Event status enable query	Queries the current contents in the Event Status Enable Register.
*ESR?	Event status register query	Queries and clears the contents in the Standard Event Status Register.
*SRE<mask>	Service request enable	Used to set the Service Request Enable Register bits, and corresponding
		Serial Poll Status Byte Register bits, to generate a service request.
*SRE?	Service request enable query	Queries the current contents in the Service Request Enable Register.
*STB?	Read status byte query	Queries the current contents in the Status Byte Register.
*TRG	Trigger	Triggers the switchbox to advance the scan when scan is enabled and
		trigger source is TRIGger:SOURce BUS.
*RCL<n>	Recall saved state	Recalls previously stored Microwave Switch module configuration.
		<n> (0 to 9) is the location in memory where the desired (previously
		stored) set-up is located.
*SAV<n>	Save state	Stores present settings of ARM:COUNt, TRIGger:SOURce,
		OUTPut[:STATe], INITiate:CONTinuous, SCAN:MODE, and
		SCAN:PORT. <n> (0 to 9) is the location in memory where the current
		set-up is located.

Note: See the HP 75000 Series B E1300/E1301 Mainframe User’s Manual or the ANSI/IEEE Standard 488.2-1987 for more information about these commands.
