HP E1459A IEEE 488.2 Common Commands

IEEE 488.2 Common Commands

The following table lists the IEEE 488.2 Common Commands listed by functional group that can be executed by the HP E1459A Digital Input / Interrupt Module. However, commands are listed alphabetically in the reference. Example are shown in the reference when the command has parameters or returns a non-trivial response; otherwise, the command string is as shown in the table. For additional information, refer to IEEE Standard 488.2-1987.

Command	Title	Description
*CLS	Clear Status Registers	Clears all STATus event registers and clears the error queue.
*ESE <mask>	Event Status Enable	Sets the bits in the Event Status Enable Register. <mask> has a range of 0 through 255 and
		must be entered in decimal format.
*ESE?	Event Status Enable Query	Returns the current programmed value of the Event Status Enable Register.
*ESR?	Event Status Register Query.	Queries and clears contents of the Standard Event Status Register.
*IDN?	Identification query	Returns the (unquoted) identification string: HEWLETT-PACKARD,E1459A/Z2404B,0,revision
*OPC	Operation Complete	This command always immediately sets the operation complete bit (bit 0) in the Standard
		Event Register because there are never any pending operations.
*OPC?	Operation Complete Query	This command always returns a 1 since there are never any pending operations.
*RCL<state>	Recalls stored instrument state	Recalls the specified stored instrument state where <state> has a value of 0 through 9. The
	from memory	following conditions or settings are saved/recalled: debounce time, positive edge detect,
		positive edge mask, negative edge detect, negative edge mask, QUEStionable and OPERation
		PSUMmary Status Enable Registers, QUEStionable and OPERation Status Event Register,
		QUEStionable and OPERation PORT Status Event Register, QUEStionable and OPERation
		PSUM Status Event Register.
*RST	Resets the module	Resets the module to the settings shown in the "Power-On and Reset State" table following the
		individual common command descriptions.
*SAV<state>	Save state to memory	Saves the present instrument state in the specified memory location (1 to 9). Refer to *RCL.
*SRE <mask>	Service Request Enable	Sets the bits in the Service Request Enable Register. <mask> has a range of 0 through 255
		and must be entered in decimal format.
*SRE?	Service Request Enable Query	Returns the current programmed value of the Service Request Enable Register.
*STB?	Status Byte	Returns the current value of the Status Byte Register.
*TRG	Bus Trigger	*TRG is not supported on the HP E1459A.
*TST?	Self-Test	Returns "0" if self-test passed. Returns "1" if read of ID register (00h) failed, returns "2" if read
		of Device Type Register (02h) failed, "20n" if interrupt test on Port n failed. Instrument state
		returned to the power-on / reset state after *TST?
*WAI	Wait to Complete	Prevents execution of commands until the No Operation Pending message is true. Since each
		command is fully executed at the time of execution, the No Operation Pending message is
		always true and the *WAI command always immediately executes when received.
*EMC <n>	Enable Macro	Enables execution of macro <n>.
*EMC? <n>	Enable macro query	Queries execution state of macro <n>.
*RMC	Remove macros	Deletes all macros.
*LMC?	List macros	Lists macros by name.
*DMC	Define macro	Defines a macro.
*GMC?	Menu query	Gets results of menu query.
*PMC	Purge macros	Purges all system macros.
