| 1150000 | ViInt32 | R/W | Session | None | None |
For sessions initialized with deprecated initialize functions, this attribute specifies the power source to use. NI-DCPower switches the power source used by the device to the specified value.
This attribute is not supported in sessions initialized with the niDCPower_InitializeWithIndependentChannels function.
Defined Values:
| NIDCPOWER_VAL_INTERNAL (1003) | Uses the PXI chassis power source. |
|---|---|
| NIDCPOWER_VAL_AUXILIARY (1004) | Uses the auxiliary power source connected to the device. Only the NI 4110 and NI 4130 support this value. |
| NIDCPOWER_VAL_AUTOMATIC (1005) | Uses the auxiliary power source if it is available; otherwise uses the PXI chassis power source. |
Default Value: NIDCPOWER_VAL_AUTOMATIC
Note Automatic selection is not persistent and occurs only at the time this attribute is set to NIDCPOWER_VAL_AUTOMATIC. However, if the session is in the Committed or Uncommitted state when you set this attribute, the power source selection only occurs after you call the niDCPower_InitiateWithChannels function for all channels in the session

A value of VI_FALSE may indicate that the auxiliary input fuse has blown. Refer to the Detecting Internal/Auxiliary Power topic in the NI DC Power Supplies and SMUs Help for more information about internal and auxiliary power.
Note This attribute does not necessarily indicate if the device is using the auxiliary power source to generate power. Use the NIDCPOWER_ATTRIBUTE_POWER_SOURCE_IN_USE attribute to retrieve this information

Specifies whether the values calculated during self-calibration should be written to hardware to be used until the next self-calibration or only used until the niDCPower_ResetDevice function is called or the machine is powered down.
This attribute affects the behavior of the niDCPower_CalSelfCalibrate function. When set to NIDCPOWER_VAL_KEEP_IN_MEMORY, the values calculated by the niDCPower_CalSelfCalibrate function are used in the existing session, as well as in all further sessions until you call the niDCPower_ResetDevice function or restart the machine. When you set this property to NIDCPOWER_VAL_WRITE_TO_EEPROM, the values calculated by the niDCPower_CalSelfCalibrate function are written to hardware and used in the existing session and in all subsequent sessions until another call to the niDCPower_CalSelfCalibrate function is made.
Note This attribute is not supported by all devices. Refer to Supported Attributes by Device for information about supported devices
Note To specify an instrument name when accessing this attribute, you must first initialize the session using the niDCPower_InitializeWithIndependentChannels function
Defined Values:
| NIDCPOWER_VAL_KEEP_IN_MEMORY (1045) | Keep new self-calibration values in memory only. |
|---|---|
