NI 5650/5651/5652 Thermal Shutdown Monitoring

If safe temperature limits are exceeded, the RF enclosure is powered off and NI-RFSG returns an error.

Re-enabling Device After Thermal Shutdown

You must perform a device reset in order to restore power to the RF enclosure. Reset the NI RF signal generator hardware by right-clicking the NI 5650/5651/5652 hardware module in MAX and selecting Reset Device or by calling the niRFSG Reset Device VI or the niRFSG_ResetDevice function.

Note  The NI 5650/5651/5652 is warm to the touch during normal operation. It should never reach a temperature high enough to cause thermal shutdown unless the fan or vents on the PXI chassis are blocked, or the filters on the fans are excessively dusty. If you get a thermal shutdown error, ensure the filters are clean and that you have a clear path for airflow through your PXI chassis. Review the guidelines in the Maintain Forced-Air Cooling Note to Users document that shipped with the product and make any necessary adjustments to ensure that the device is cooled effectively.
