The Boonton 57518 power sensor is a compact RF peak power sensor covering 0.1 to 18 GHz, with both pulse and CW power measurements over a –40 to +20 dBm dynamic range and a 50 Ω impedance.

Together with RF digital power meter Boonton 4542/1 , the 57518 supports automatic zeroing and calibration, for simplified setup prior to a measurement and a sampling rate of 100,000/sec for recording of  the signal. 

A cable 1.6 meters in length, compatible with the 4542 meter, is included
