SFS Series Microwave Analog Signal Generator

Overview Specifications Ordering Resources

Saluki SFS series microwave analog signal generator is an ultra-low phase noise, high power, multi-channel output microwave signal source. The product frequency covers from 9kHz to 12, 24, 40, 45 and 67GHz, with a frequency resolution as low as 0.001Hz. It also has a narrow pulse modulation function, which can realize multi-channel coherent signal output. A single machine can support up to 8 channels. The frequency and power of each channel can be independently adjusted or linked together. It supports adjustable phase and dual-tone signal output. The SLFS series microwave analog signal source has excellent performance in applications requiring excellent phase noise, large dynamic output power range, multi-channel simultaneous testing and portability. It is a very cost-effective microwave analog signal source.
