Command

Description

 

VMAX <voltage>

Sets an upper soft limit on the supply’s programmed output voltage. If the

 

soft limit is exceeded, or if the soft limit value is lower than the present

 

output voltage setting, the supply will ignore the command, turn on the

 

ERR LED, and set the ERR bit in the accumulated status register.

 

Range: 0 to model maximum output voltage (VMAX)

 

Initial value: model VMAX

 

 

 

VMAX?

Asks for the supply’s soft voltage limit setting.

 

Response: VMAX <voltage>

 

VOUT?

Measures the supply’s actual voltage output using the built-in voltage

 

readback circuitry.

 

Response: VOUT <voltage>

 

VRDAT <Vlo>,<Vhi>

Calculates and records the slope and offset for readback voltage using

 

VRLO and VRHI data. Set CMODE ON before using this command. See

 

also the calibration procedures in Section 4 .

 

<Vlo> and <Vhi> are in <voltage> format.

 

 

 

VRHI

The power supply outputs a voltage value to an external voltmeter

 

connected as part of the calibration procedure and records a voltage

 

readback value internally. These values are at the high end of the

 

programmed voltage range. Refer to the output value as VRHI and record it

 

to use as input with the VRDAT command. Set CMODE ON before using

 

this command. See also the calibration procedures in Section 4.

 

 

 

VRLO

The power supply outputs a voltage value to an external voltmeter

 

connected as part of the calibration procedure and records a voltage

 

readback value internally. These values are at the low end of the

 

programmed voltage range. Refer to the output value as VRLO and record

 

it to use as input with the VRDAT command. Set CMODE ON before using

 

this command. See also the calibration procedures in Section 4.

 

 

 

VSET <voltage>

Sets the power supply’s output voltage in volts (default) or in millivolts. This

or

programmed voltage is the actual output in CV (constant voltage) mode or

VSET <-voltage>

the voltage limit in CC (constant current) mode.

 

If you enter a negative voltage value, the power supply will assert a signal

 

on the J21-4 user signal line. You can use the user signal to trip external

 

relays to switch the output polarity.

 

Range: 0 to model maximum output voltage (VMAX)

 

Initial value: 0 volts

 

VSET?

Asks for the power supply’s present output voltage setting. Does not apply

 

to voltage settings which are being held. See HOLD command.

 

Response: VSET <voltage>
