User Manual
Introduction
The TBCG3-CN
produces a comb spectrum with approximately 8 dB flatness in the frequency
range up to 1.5 GHz and has a 50 Ohm output with a female N- connector. The
housing is milled from solid aluminum. A ¼” – 20 UNC thread in the comb panel
accepts standard tripod bolts.

Application
Checking the sanity of a LISN or conducted emission measurement setup.
There is no need to swap the N-connectors of the LISN adapter cable to switch
between LISN channels, when utilizing a TBRFPS1 power splitter:
Warning:
Never connect the comb generator or the comb generator adapter cable to a
powered LISN to avoid potentially lethal electric shock. Before connecting the
comb generator adapter cable into the DUT / EUT socket, always unhook the
mains connector on the back of the LISN.
Never plug the comb generator adapter cord into a power outlet to avoid
potentially lethal electric shock.
Inserting/replacing batteries
Loosen the SMA-connector nut a few turns. Remove the six screws at the bottom
of the comb generator housing, lift it, and insert four AA rechargable 1.2V
NiMH batteries. Both the battery compartment and the PCB indicate the
polarity.
Reattach the bottom cover, then tighten the screws and the SMA-connector nut.
