VOLTage:PROTection? {MINimum|MAXimum}
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 {0|1|OFF|ON}
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 {P8V|P20V||LOW|HIGH} (For E3633A model)
or {P25V|P50V|LOW|HIGH} (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 70 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.
