This optional amplifier is a low-noise, wide-bandwidth amplifier designed for use with the 100 series EMI / EMC probes. It features a gain of over 30 dB and a frequency response of 100 kHz to 6 GHz.

Its high gain and low noise improve the system sensitivity by 20 to 30 dB. This higher sensitivity allows the user to widen the spectrum analyzer resolution bandwidth, resulting in faster sweeps and measurements, 10,000 faster or more.

Standard 50 ohm SMA(f) inputs and outputs allow it to be used in any application requiring a low noise amplifier. RF input and output are protected against ESD and DC power. 

AC power supply is included. Probe cable or adapters are suggested to connect to probes.
