Output Setting and Operation Commands

VOLTage:PROTection? {MINimumMAXimum}

This query returns the overvoltage protection trip level presently programmed. VOLT:PROT? MAX and VOLT:PROT? MIN return the maximum and minimum programmable overvoltage trip levels.

VOLTage:PROTection:STATe {01OFFON}

This command enables or disables the overvoltage protection function. An overvoltage condition can be cleared with the VOLT:PROT:CLE command after the condition that caused the OVP trip is removed. At *RST, this value is set to ‘‘ON’’.

VOLTage:PROTection:STATe?

This query returns the state of the overvoltage protection function. The returned parameter is ‘‘0’’ (OFF) or ‘‘1’’ (ON).

VOLTage:PROTection:TRIPped?

This query returns a ‘‘1’’ if the overvoltage protection circuit is tripped and not cleared or a ‘‘0’’ if not tripped.

VOLTage:PROTection:CLEar

This command causes the overvoltage protection circuit to be cleared. After this command, the output voltage is restored to the state it was in before the protection feature occurred and the OVP trip level remains unchanged to the value presently programmed. Before sending this command, lower the output voltage below the trip OVP point, or raise the OVP trip level above the output setting. Note that the overvoltage condition caused by an external source must

be removed first before proceeding this command.

VOLTage:RANGe {P8VP20VLOWHIGH}	(For E3633A model)
or {P25VP50VLOWHIGH}	(For E3634A model)

This command selects an output range to be programmed by the identifier. For example, when 8V/20A* range is selected, the maximum programmable voltage and current are limited to 8.24 volts and 20.60 amps. When 20V/10A* range is selected, the maximum programmable voltage and current are limited to 20.60 volts and 10.30 amps. See page 82 for more details of the programming ranges of the Agilent E3634A model. ‘‘P20V’’* or ‘‘HIGH’’ is the identifier for the 20V/10A* range and ‘‘P8V’’* or ‘‘LOW’’ is for the 8V/20A* range. At *RST, the 8V/20A* or 25V/7A** range is selected.
