5MHz Step, 1.5GHz Comb Generator The CG-515 Series Comb Generators are reference signal sources providing frequency harmonics at preset frequency intervals. The output signal of the Comb Generator is used as a conducted or a radiated signal source. As a conducted signal source, the output is available directly from the connector. Two antennas are supplied with the Comb Generator for generating radiated reference signals. The Comb Generator is powered by a rechargeable internal battery. Battery power eliminates any possible measurement variations that can be caused by an external power cable connection. When fully charged, the battery allows continuous operation for up to 18 hours. Internal control and monitoring circuits provide indications of valid output signals. A battery charger is included with the Comb Generator. The Comb Generator and accessories are shipped in a wooden storage box.
The CGC series Comb Generator was specifically designed to test installed Line Impedance Stabilization Networks (LISNs). LISNs are used for EMC conducted emissions testing according to FCC Part 15, CISPR, and EN requirements. The Comb Generator output is connected to the LISN EUT power port and measurements are taken similar to an EUT. For convenience, the CGC series Comb Generators have 3 prong standard US plug for LISNs with matching EUT power socket. By using the Comb Generator the test engineer can quickly identify any problems with the conducted setup before making any measurements with an EUT. the Application Note AN-104 provides more details on the Comb Generator.
