Comb Generators

​Model CGO-51000 Comb Generators is a broadband
EMC signal reference source for quick EMC site testing. It radiates signals up to 40 GHz at 1 GHz frequency steps. EMC labs calibrate their radiated emissions test sites, instrumentation and accessories at least once a year. The calibration procedures are elaborate and time consuming. However, calibration does not prevent equipment malfunction in between calibration period such as damaged receivers, broken cables, poor connections, bad antenna, etc. For example, as the frequency increases poorly mated connector can cause significant measurement errors. Monitoring a few frequencies regularly on the Comb Generator’s broadband radiated output can verify the entire setup quickly and efficiently. Any potential problems with the test setup can be detected before it causes erroneous results. It is powered by a rechargeable NimH battery pack. It has circular shape for more uniform radiated output.


​This Line Impedance Stabilization Network
(LISN) provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products. The LI-150A is compliant with both CISPR 16-1-2 and ANSI C63.4. The LISN provides defined stable impedance and isolates the EUT from power source influences, thereby providing accurate and repeatable results. The LI-150A includes one pair of, separately housed, single-conductor networks, to be installed in series with each current-carrying conductor in a single- phase, dual-phase or DC power system. A second LI-150A pair can be used to accommodate 3-phase power systems (Wye or Delta configurations). The LI-150A is equipped with Superior Electric SUPERCON® shrouded sockets at the mains (power input) and EUT (power output) ports. The matching color-coded plugs for connection to the mains and EUT wiring are included. This LISN uses air-core inductors to prevent saturation and permeability variation. The mounting plate of the LI-150A is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current.
