NIDCPOWER_ATTR_VOLTAGE_LEVEL_RANGE
Specific Attribute
| Data type |
Access | Applies to | Coercion | High-Level Functions |
|---|---|---|---|---|
| ViReal64 | R/W | Channel | Yes | niDCPower_ConfigureVoltageLevelRange |
Description
Specifies the voltage level range, in volts, for the specified channel(s). The range defines the valid values to which the voltage level can be set. Use the NIDCPOWER_ATTR_VOLTAGE_LEVEL_AUTORANGE attribute to enable automatic selection of the voltage level range.
The NIDCPOWER_ATTR_VOLTAGE_LEVEL_RANGE attribute is applicable only if the NIDCPOWER_ATTR_OUTPUT_FUNCTION attribute is set to NIDCPOWER_VAL_DC_VOLTAGE.
The channel must be enabled for the specified voltage level range to take effect. Refer to the NIDCPOWER_ATTR_OUTPUT_ENABLED attribute for more information about enabling the output channel.
Valid Values:
NI PXI-4110
| Channel | Voltage Level Range (V) | Voltage Level (V) |
|---|---|---|
| 0 | 6 | 0 to +6 |
| 1 | 20 | 0 to +20 |
| 2 | 20 | 0 to -20 |
NI PXI-4130
| Channel | Voltage Level Range (V) | Voltage Level (V) |
|---|---|---|
| 0 | 6 | 0 to +6 |
| 1 | 6 | -6 to +6 |
| 20 | -20 to +20 |
 |
Note If a range other than what is listed in the preceding table is selected, it will be coerced to the next-highest level. For example, requesting the 10 V voltage level range on Channel 1 on the NI-PXI 4130 coerces the voltage level range to 20 V. Refer to the Ranges topic in the NI DC Power Supplies and SMUs Help for more information about coercion. |
