NI 5650/5651/5652 User Querying

Querying the value of the Device Temperature (°C) property or the NIRFSG_ATTR_DEVICE_TEMPERATURE attribute returns the temperature within the NI 5650/5651/5652 RF enclosure. This metal enclosure contains the RF circuitry.

Note  Serial signals between the sensor and the system control unit could potentially modulate the signal being generated, causing phase spurs. After the device is thoroughly warmed up, its temperature varies only slightly and slowly, so it is not necessary to constantly poll this temperature sensor. For these reasons, NI-RFSG reads the temperature sensor at most every minute. Queries to the the Device Temperature (°C) property or the NIRFSG_ATTR_DEVICE_TEMPERATURE attribute return the previous sensor reading until at least one minute has passed since the previous sensor reading occurred.
