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.
