Command Reference

Table 3-7Command Reference

UNMASK?	Asks for the supply's fault conditions which are currently enabled (unmasked).
	R ponse: UNMASK <fault mask> where fault mask is the decimal equivalent of
	the total bit weights for the operating conditions as listed in the status and fault
	registers See “Accumulated Status, Status, and Fault Registers” on page 3–17.
VDATA	Calculates a d records the slope and offset for programmed voltage using VLO
<Vlo>,<Vhi>	and VHI data. Set CMODE ON before using this command. See also the
	calibration procedures in Chapter 4.
	<Vlo> and <Vhi> are in <voltage> format.
VHI	In response to this command, the power supply sends a programmed voltage value
	to the ou put terminal. This value is at the high end of the power supply’s voltage
	range and is read by an external device connected as part of the calibration
	procedure. Refer to this value as VHI and record it to use as input with the VDATA
	command. Set CMODE ON before using this command. See also the calibration
	procedures in Chapter 4.
VLO	In response to this command, the power supply sends a programmed voltage value
Command	to the ou put terminal. This value is at the low end of the power supply’s voltage
	range and is read by an external voltmeter connected as part of the calibration
	Descriptionprocedure. Refer to this value as VLO and record it to use as input with the
	VDATA command. Set CMODE ON before using this command. See also the
	calibration procedures in Chapter 4.

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	Calculates and records the slope and offset for readback voltage using VRLO and
<Vlo>,<Vhi>	VRHI data. Set CMODE ON before using this command. See also the calibration
	procedures in Chapter 4 .
	<Vlo> and <Vhi> are in <voltage> format.
