TekBox 40dB Wideband Amplifier (TBWA2/40dB)


The TBSWA2/20dB and TBSWA2/40db wideband amplifiers are designed to be connected between a near field probe and a spectrum analyzer to increase the dynamic range of the measurements.

This will help to detect emission that may otherwise be swamped below the noise floor of your spectrum analyzer.
