Typically, the TBCG3-RN2 is used in a shielding chamber, the diagrams of the radiated emission can be used as a reference to compare a DUD in a non-ideal environment with the comb generator at the same location. A rotary switch can be used to select between five fixed comb frequencies and an external comb frequency input in the range from 5 kHz to 200 MHz. can be selected. A switchable RF amplifier can amplify the output signal by 20 decibels (dB).
