30 kHz to 100 MHz, C Series RF Receiver Module—The NI‑9770 is a single-channel module designed for machine condition monitoring applications. The NI‑9770 can measure RF emissions. This bandwidth can be configured as a narrow range to help detect electircal anomalies, often considered a leading indicator of machine failure. The NI‑9770 can detect partical discharge, corona discharge, arcing, and any other phenomena that results in RF emissions. You can also perform electromagnetic signature analysis (EMSA) by monitoring signals over a period of time using a swept frequency representation.
