RMS Power Sensor with 8dB attenuation (for reflected Power)

Login for your best price

The RMSPS is a RMS RF Power Sensor designed to detect the power levels of complex RF waveforms such as DTV, CDMA and multiple transmitter signals combined onto a single antenna line for example. The power sensor is normally connected to an in-line directional coupler that allows signal sampling in both the forward and reflected directions.


The sensor comes in two versions. The Model RMSPS20 has a 20 dB RF attenuator at its input and is normally used for forward power measurements while the Model RMSPS8 has an 8 dB attenuator and is intended for reflected power measurements. Both sensors have a wide dynamic range and RF bandwidth.


These sensors are a perfect complement for the Davicom units.
