Command Description
VDATA , Calculates and records the slope and offset for programmed voltage using
VLO and VHI data. Set CMODE ON before using this command. See also
the calibration procedures in Section 4.
and are in format.
VHI In response to this command, the power supply sends a programmed
voltage value to the output 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 Section 4.
VLO In response to this command, the power supply sends a programmed
voltage value to the output 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 procedure. 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
Section 4.
VMAX 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? Returns the supply’s soft voltage limit setting.
Response: VMAX
VOUT? Measures and returns the supply’s actual voltage output using the built-in
voltage readback circuitry.
Response: VOUT
VRDAT , 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 .
and are in 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.
