Tekbox TBCG3-RN2 Comb Generator

The Tekbox TBCG3-RN2 comb generator is primarily intended for testing radiated emission setups. It is a useful tool for validating the proper operation of the antenna and pre-amplifier, as well as the accurate set-up and configuration of the spectrum analyzer. It is well characterized in an anechoic chamber and the radiated emission plots can be used as a reference to compare an EUT in a non-ideal setup against the comb generator in the same location.

You can select between five fixed comb frequencies and an external comb frequency input with a range of 5 kHz to 200 MHz using a rotary switch.

A switchable RF amplifier may increase the output signal by 20 decibels (dB).
The comb generator comes with two monopole antennas, a 30 cm monopole for frequencies up to 300-500 MHz and a 10 cm monopole for frequencies above that.
The radiated comb spectrum is characterized from 5 MHz – 6 GHz.

The Tekbox TBCG3-RN2 has a 50 Ohm output with a female N-connector. It runs on six AA NiMH batteries and comes with an external charger.
The housing is machined of solid aluminium. The bottom panel has a 1/4″ – 20 UNC thread that accepts regular tripod bolts.
