Device Temperatures

Remarks


If the NI-RFSG session is controlling multiple devices, this attribute returns the temperature of the primary NI RF device. The NI-RFSG session is opened using the primary RF device name.

Serial signals between the sensor and the system control unit could modulate the signal being generated, thus causing phase spurs. After the device thoroughly warms up, its temperature varies only slightly (less than 1 degree Celsius) and slowly, and it is not necessary to constantly poll this temperature sensor.

PXIe-5644/5645/5646, PXIe-5820/5840/5841: If you query this attribute during RF list mode, list steps may take longer to complete during list execution.

PXIe-5830/5831/5832: To use this attribute, you must first set the channelName parameter of the niRFSG_SetAttributeViReal64 function to using the appropriate string for your instrument configuration. Setting the niRFSG_SetAttributeViReal64 function is not required for the PXIe-3621/3622. Refer to the following table to determine which strings are valid for your configuration.
