CGC-510E 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 100 kHz and 500 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-510E 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.
