Temperature Monitoring

Both the PXIe-5654 RF signal generator module and the PXIe-5696 Amplitude Extender module have an internal temperature sensor that monitors the RF analog circuitry temperature. You can query these internal temperature sensors using NI-RFSG .

The PXIe-5654 RF signal generator module queries its temperature sensor at defined intervals to correct for amplitude deviations as the operating temperature and ambient temperature changes. NI-RFSG polls the temperature sensor of the PXIe-5696 to correct for amplitude deviations as the operating temperature and ambient temperature changes.

Note If a temperature sensor reports a temperature above 80 °C, the PXI Express power rails to the RF signal generator or amplitude extender shuts down to protect the RF circuitry from damage.
