Language Dictionary 39

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 max imum programmable d elays.
