Agilent Technologies 75000 SERIES B Gpib Message, Go To Local GTL, Group Execute Trigger GET

GPIB Message	This section describes IEEE -488.1 defined messages and their affect on
Reference	instruments installed in the mainframe. The examples shown are specifically for
	HP 9000 Series 200/300 computers using BASIC language. Any IEEE -488
	controller can send these messages; however, the syntax may be different from
	that shown here.
Go To Local (GTL)	Places an instrument in local state.

Comments	• Refer to the Local Lockout message, later in this chapter, for information
	on how GTL affects front panel lockout.
Examples	LOCAL 7	Sets GPIB remote enable line
		false (all instruments go to
		local). (You must now execute
		REMOTE 7 to return to remote
		mode).
	LOCAL 70900	Issues GPIB GTL to System
		Instrument. (The instrument

will return to remote mode when it is listen addressed.)

Group Execute Trigger (GET)

Comments

Executing a group execute trigger will trigger an instrument assuming the following conditions are true:

•The instrument’s trigger source is set to Bus (TRIG:SOUR BUS command), and:

•The instrument is in the Wait For Trigger state, and:

•The instrument is addressed to listen (can be done by sending any

command, the REMOTE 709ss (ss = secondary address) command, or with the LISTEN command).

•For instruments in an Agilent E1300B/E1301B Mainframe, only one instrument at a time can be programmed to respond to GET. This is because only one instrument can be addressed to listen at any one time.

Example	10 OUTPUT 70900;"TRIG:SOUR BUS"	Sets trigger source to bus
	20 OUTPUT 70900;"INIT:IMM"	Places System Instrument’s
		Pacer in Wait For Trigger state
	30 TRIGGER 70900	Triggers Pacer
	40 END
Interface Clear (IFC)	Unaddresses all instruments in the mainframe and breaks any bus handshaking
	in progress.
Example	ABORT 7
