Outpttlt 1 Outpttlt OFF | Agilent Technologies 66lxxA instruction

OUTP:TTLT

This command enables or disables the power module Trigger Out signal, which is available at a BNC connector on the rear of the mainframe. Trigger Out is the logical OR of all the power module TTLTrig signals (see "Chapter 5 - Synchronizing Power Module Output Changes"). It also may be selected as a trigger input (see TRIGger:SOURce).

Command Syntax	OUTPut:TTLTrg[:STATe] <bool>
Parameters	0 1 OFF ON
*RST Value	OFF
Examples	OUTP:TTLT 1 OUTP:TTLT OFF
Query Syntax	OUTPut:TTLrg[:STATe]?
Returned Parameters	0 1
Related Commands	OUTP:TTLT:LINK OUTP:TTLT:SOUR

OUTP:TTLT:LINK

This command specifies which events within the power module are linked to TTLTrg source events when LINK is the parameter for the OUTP:TTLT:SOUR command.

Command Syntax	OUTPut:TTLrg:LINK <CRD>
Parameters	See Table 3-1
*RST Value	OFF
Examples	OUTP:TTLT:LINK "CC"	OUTP:TTLT:LINK "OFF"
Query Syntax	OUTPut:TTLrg:LINK?
Returned Parameters	See Table 3-1
Related Commands	OUTP:TTLT:SOUR	OUTP:TTLT[:STAT]

OUTP:TTLT:SOUR

This command selects the signal source for the Trig Out signal as follows:

BUS	*TRG or <GET> (Group Execute Trigger)	HOLD	No trigger source except TRIG:IMM
EXT	Mainframe backplane Trigger In bus	LINK	Internal power module event as
			specified by TRIG:LINK

When an event becomes true at the selected TTLTrg source, a pulse is sent to the BNC connector on the rear of the mainframe.

Command Syntax	OUTPut:TTLrg:SOURce <CRD>
Parameters	BUS EXTernal LINK HOLD
*RST Value	BUS
Examples	OUTP:TTLT:SOUR LINK
Query Syntax	OUTPut:TTLrg:SOURce?
Returned Parameters	BUS EXT LINK HOLD
Related Commands	OUTP:TTLT:LINK OUTP:TTLT[:STAT]

Status Subsystem

This subsystem programs the power module status registers. The power module has three groups of status registers; Operation, Questionable, and Standard Event. The Standard Event group is programmed with Common commands as described in "Chapter 4 - Status Reporting". The Operation and Questionable status groups each consist of the following five registers:

Condition

Enable Event NTR Filter

PTR Filter
