The SG-CG2 wideband comb generators were developed for quick microwave receiving equipment test under various conditions. Quick and simple usage was one of the primary design goals. The SG-CG2 transmitters generate a crystal referenced fundamental frequency of 1.00 GHz and generate harmonics on whole-number multiples of the fundamental, up to 40 GHz and beyond, via non-linear elements. The generated frequency comb is then radiated by an internal wideband microwave antenna with an antenna gain of 0 dBi.
An internal wideband antenna increases ruggedness as no external precision microwave connectors are necessary. Other features include a stand alone system with internal 9 V battery holder or external DC supply possible; compact and rugged case, ideal for portable and field use; and internal low noise oscillator and high power comb oscillator.
Applications include EMC-test in the GHz-range; free space antenna tests and antenna measurements; rapid test of measurement equipment such as spectrum analyzers; EMC source and EMC shielding tests; rapid test of wideband receivers as well as broad band test equipment, microwave RX intermodulation tests, and interference emission location and direction finding training.
