Voltage Subsystem
This subsystem programs the output voltage of the power module.
VOLT
This command directly programs the immediate voltage level of the power module. The immediate level is the voltage
applied at the output terminals. This command is always active, even when the voltage subsystem is in the list mode (see
VOLT:MODE).
Command Syntax [SOURce]:VOLTage[:LEVel] [:IMMediate][:AMPLitude] <NRf+>
Parameters Table 3-2
Default Suffix V
*RST Value Table 3-2
Examples VOLT 2500 MV VOLT:LEV 2.5
Query Syntax [SOURce]:VOLTage[:LEVel] [:IMMediate][:AMPlitude]?
[SOURce]:VOLTage[:LEVel] [:IMMediate][:AMPLitude]? MAX
[SOURce]:VOLTage[:LEVel] [:IMMediate][:AMPLitude]? MIN
Returned Parameters <NR3> VOLT? returns the presently programmed immediate voltage
level.
VOLT? MAX and VOLT? MIN return the maximum and minimum
programmable immediate voltage levels.

VOLT:MODE
This command enables or disables list subsystem control over the power module output voltage. When programmed with
FIX, this command prevents the output voltage from being controlled by the sequencing of points specified by
LIST:VOLT. If the LIST parameter is used, then the output voltage may be changed by the subsequent execution of a list.
However, the list mode does not prevent the output voltage from being set by VOLT[:IMM] and *RCL.
Note VOLT:MODE LIST is an implied ABORT command.

VOLT:PROT
This command sets the overvoltage protection (OVP) level of the power module. If the output voltage exceeds the OVP
level, then the power module output is disabled and the Questionable Condition status register OV bit is set (see "Chapter 4
- Status Reporting"). An overvoltage condition can be cleared with the OUTP:PROT:CLE command after the condition
that caused the OVP trip is removed. The OVP always trips with zero delay and is unaffected by the OUTP:PROT:DEL
command.
