SG 9302 C, 0.1-18 GHz Comb Generator


 
The comb-generator SG 9302 C produces a frequency spectrum consisting of lines with 100 MHz spacing up to 18 GHz. In combination with an antenna, it can be used as an emission source for testing open area test sites, anechoic chambers, or GTEM-cells. Single components like measuring receivers, spectrum analyzers, cables, and attenuators can be tested as well.
The operation is very simple and time-saving because the spectrum lines are always present without any tuning procedure. The built-in rechargeable battery makes it a versatile, simple, and cost-effective substitute for signal generators.
The output level is relatively high for a comb-generator and the lines go well beyond 18 GHz. The limit for N- connectors is 18 GHz, so this limit is also given for the generator, though the spectrum is wider.
A VCTCXO is used as a frequency standard.
This abbreviation stands for “Voltage Controlled Temperature Compensated Crystal Oscillator”.
The very good frequency stability of a crystal is made even better by a compensation circuit. Furthermore, the nominal frequency can be tuned in a narrow range using a tuning voltage. This makes it possible to compensate for small frequency differences between the comb-generator and a receiver. In open area test sites collisions with environmental signals can be avoided by tuning the frequency slightly.
