Output Subsystem

Output Subsystem

This subsystem controls the power supply's voltage and current outputs and an optional output relay.

Do not install or program the Agilent Relay Accessories if the power supply maximum output current rating (see Table 3-1) exceeds the contact ratings of the relay.

OUTP

This command enables or disables the power supply output. The state of a disabled output is a condition of zero output voltage and a model-dependent minimum source current (see Table 3-1). The query form returns the output state.

Commandd Syntax	OUTPut[:STATe] <bool>
Parameters	0 OFF 1 ON
Suffix	(None)
*RST Value	0
Examples	OUTP 1	OUTPUT:STATE ON
Query Syntax	OUTPut(:STATe]?
Returned Parameters	<NR1>	0 or 1
Related Commands	*RST	RCL SAV

OUTP:PROT:CLE

OUTP:PROT:DEL

OUTP:PROT:CLE Clears any OV (overvoltage), OC (overcurrent, unless set via external voltage control),OT (overtemperature), or RI (remote inhibit) protection features. After this command, the output is restored to the state it was in before the protection feature occurred.

OUTP:PROT:DEL Sets the time between the programming of an output change that produces a CV, CC, or UNREG condition and the recording of that condition by the Status Operation Condition register. The delay prevents the momentary changes in power supply status that can occur during reprogramming from being registered as events by the status subsystem. Since the delay applies to CC status, it also delays the OCP (overcurrent protection) feature. The OVP (overvoltage protection) feature is not affected by this delay.

Examples	OUTP:PROT:CLE OUTPUT:PROTECTION:CLEAR
	OUTPUT:PROTECTION:DELAY 75E-1
	OUTP:PROT:DEL MIN	OUTPUT:PROT:DELAY MAX
Query Syntax	OUTP:PROT:CLE	(None)
	OUTPut:PROTection:DELay?		OUTPut:PROTection:DELay? MIN
	OUTPut:PROTection:DELay? MAX
Returned Parameters	<NR3> OUTP:PROT:DEL? returns value of programmed delay.
	OUTP:PROT:DEL? MIN and OUTP:PROT:DEL? MAX return
	the minimum and maximum programmable delays.
