Command Reference
Table
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 |
|
|
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 |
| 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. |
