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
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
Programs the immediate output current level (in amperes).
CURR:TRIG
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
Programs the immediate output voltage level (in amperes).
VOLT: TRIG
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).
