The Com-Power CGC-255E Comb Generator is a conducted
reference signal source to test Line Impedance
Stabilization Network (LISN). The Comb generator
output has the harmonics of the fundamental
frequency. It has two user selectable frequency
step sizes of 50 kHz and 250 kHz.
This Comb Generator simulates an EUT generating
conducted EMI noise. The CGC series Comb
Generators have the standard NEMA three blade
connector that can plug directly into any LISN with
the matching EUT power socket. It can be attached
to any other socket type using suitable adapter.
The CGC-255E has high impedance to the external
line voltage, AC or DC up to 230 V. This feature
allows the Comb Generator to be used while the
LISNs are connected to external power source.
The CGC-255E is powered by rechargeable internal
NimH batteries. The battery power eliminates the
need for an external cabling that may interfere
with the radiated signals. When fully charged,
the battery allows continuous use of the Comb
Generator for up to 18 hours. The Comb Generator
and the charger are shipped with a custom wooden
storage box.

The main application of the CGC-255E Comb
Generators is to quickly verify conducted emissions
test setups. It is designed to plug directly into the
EUT power socket of the LISN. The conducted noise
output level of the Comb Generators are close to
or above the CISPR 22 limits. Typical output plot is
shown on the next page.
Most EMI labs typically calibrate LISNs and
other equipment (spectrum analyzers, cables,
connectors, etc.) in the conducted emissions test
setup at regular intervals. However, test equipment
malfunctions may occur between any calibration
interval and may go undetected until the next
calibration. In the meantime, these malfunctions
may produce erroneous test results. The time and
resources lost due to these unforeseen errors can
be avoided with the help of Comb Generator. With
the Comb Generator, the test engineer will be able
to quickly perform verification of the conducted
test setup more frequently to assure accurate test
results.
Other possible applications of the CGC-255E Comb
Generator could include production evaluation of
components, such as cable shields and filters.
