TBCG3-RN6 Comb Generator

1 Introduction
The TBCG3-RN6 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.
The 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.
The radiated comb spectrum is characterized from 5 MHz – 6 GHz.

The TBCG3-RN6 has a 50 Ohm output with a female N-connector. The unit operates on six
AA NiMH batteries and is supplied with an external charger.
The housing is machined from solid aluminium. The bottom lid is fitted with a 1/4" - 20 UNC
thread that accepts regular tripod bolts.

Warning: the TBCG3-RN6 radiates across a wide spectrum, significantly exceeding radiated
emission limits specified in any CISPR standard. Use it only in a shielded environment to
avoid interference with other electronic products.
3 Characterization
The comb generator was tested in an anechoic chamber at 1 meter height and 3 meters from
the antenna. The antenna was mounted at a fixed height of 1m.
The test plan, test report, and the associated CVS files contain the raw data (antenna voltage)
and can be downloaded from the Tekbox website. Due to a restriction of the test tool, the
amplitude axis of the charts in the test report is incorrectly labelled dBµV/m. It is, in reality,
dBµV.
The data package also includes the data sheets and antenna factors for the measurement
antennas involved. The processed raw data including conversion into electric field-strength is
stored in the Excel file TBCG3_RN6_summary.xlsx.

7 Inserting / replacing batteries
Due to airfreight regulations concerning batteries, the TBCG3 is not supplied with batteries.
Loosen the SMA-connector nut a few turns. Remove the six screws at the bottom of the comb
generator housing and take off the bottom lid. Insert six AA rechargable 1.2V NiMH batteries
in the battery compartments taking care to follow the polarity indicated on the PCB.
Reattach the bottom lid, then tighten the screws and the SMA-connector nut as well.
Before connecting the charger plug to the unit connector, please check that the centre tip
polarity is shown as (positive) “+”.
