Comb generator 0.1-18GHz spectrum lines every 100MHz

Comb-generator: SG 9302 C

What the product is

The SG 9302 C is a comb-generator from SCHWARZBECK, designed to provide a regular line spectrum with 100 MHz spacing. The unit uses an N-female, 50 Ω output and a VCTCXO as a frequency standard. It is battery-powered with a 3.7 V / 2.6 Ah Li-ion battery pack and is intended for portable, laboratory, and chamber use.

What it does and how it is used

The SG 9302 C produces spectral lines from 0.1 GHz up to 18 GHz (the unit's spectrum extends beyond 18 GHz, but the N-connector is specified for 18 GHz). The lines have a fixed spacing of 100 MHz, allowing for quick comparative measurements without the need for frequency adjustment. Frequency stability is controlled by a VCTCXO with a specified frequency error of ±1.5×10^-6 in the range of -20°C to +70°C. Typical connections and operation:

• Output: N-female, 50 Ω
• Battery operation: 3.7 V, 2.6 Ah Li-ion, typical operating time 8 hours
• Operation: fine adjustment of the reference frequency via a -∆f/+ control

Safety and measurement practice notes (from the manufacturer):

• Never connect the generator's output directly to a receiver or spectrum analyzer without attenuation.
• The manufacturer recommends using a 10 dB attenuator between the generator and measurement equipment.

Typical applications

The SG 9302 C can be used as an emission source in combination with an antenna for verifying open-field measurements, anechoic chambers, or GTEM cells. It can also be used for monitoring and controlling individual components such as measuring receivers, spectrum analyzers, cables, and attenuators, where a broad spectral line pattern is desired.
