32 Basic Power Module Commands

Controlling the Output State

The following commands control the power module output state:

Table 4-1. Power Module Output Commands

Command

Function

OUTP ON

Enables the output.

OUTP OFF

Disables the output.
(If an optional output relay is installed, the command is executed in a sequence that prevents
"hot switching".)

OUTP1,NOR

Enables the output without affecting the output relay.

OUTP 0,NOR

Disables the output without affecting the output relay.

OUTP: REL 1

Closes the (optional) output relay contacts.

OUTP:REL 0

Opens the (optional) output relay contacts.

OUTP:REL:POL NORM

Makes the (optional) output relay polarity the same as the module output.

OUTP:REL:POL REV

Makes the (optional) output relay polarity opposite to the module output. The output is
disabled while the relay polarity is being reversed.)

Controlling Protection Functions

The following commands control the power module protection circuits.

Table 4-2. Power Module Protection Commands

Command

Function

CURR:PROT:STAT ON

Turns on the OCP (overcurrent protection), which disables the output if the output
current exceeds the programmed current.

CURR: PROT: STAT OFF

Turns off the current protection.

VOLT:PROT <value>

Programs the OVP (overvoltage protection) level. The protection circuit will trip if the
output voltage exceeds the OVP level.

OUTP:PROT:CLE

Clears any active protection conditions (panel Prot annunciator goes off). Before the
command can comply, you must remove the condition that caused the protection circuit
to trip.

OUTP:PROT:DEL .05

Specifies a delay (in seconds) between the time a protection condition is detected and
the actual activation of the protection circuit. (Does not apply to OVP.)

Controlling Fixed-Mode Output


The following commands control the power module fixed-mode voltage and current output.

Table 4-3. Power Module Fixed-Mode Output Commands

Command

Function

CURR:MODE FIX

Sets the current mode to fixed (as opposed to list). FIX is the factory default power on
state.

CURR <value>

Programs the immediate output current level (in amperes).

CURR:TRIG <value>

Programs the triggered output current level (in amperes). See "Trigger Commands".

MEAS:CURR?

Returns the present value of the output current.

VOLT:MODE FIX

Sets the voltage mode to fixed (as opposed to list). FIX is the factory default power on
state.

VOLT <value>

Programs the immediate output voltage level (in amperes).

VOLT: TRIG <value>

Programs the triggered output voltage level (in amperes). See "Trigger Commands".

MEAS:VOLT?

Returns the present value of the output voltage.

VOLT:SENS?

Returns the position of the output connector sense switch (INT is local; EXT is remote).
