The TBCG3-RN2 from Tekbox Digital Solutions is a comb generator that is characterized from 5 MHz to 6 GHz and intended for testing radiated emission setups. It has a comb spectrum flatness of 8 - 12 dB at the RF connector and amplitude stability of less than 0.2 dB. This comb generator has an output power of -5 dBm at 100 MHz and aging of less than 0.5 dB over 12 months. It has selectable fixed comb frequencies of 100 MHz, 50 MHz, 25 MHz, 10 MHz, and 5 MHz with a frequency stability of 50 ppm. It is equipped with 6 x AA NiMH cells for power supply and an external Ansmann ACS310 charger. It has an operation time of battery capacity / 96 mA (ampl. off) or 181 mA (ampl on). This generator measures 180 x 60 mm (housing diameter x height) and weighs about 1250 g. This radiated comb generator is supplied with two monopole antennas, a 30 cm monopole for frequencies below 300-500 MHz and a 10 cm monopole for frequencies above that.
