Frequency Synthesizers

Frequency Synthesizers

Frequency Synthesizers come in 3U rack-mount chassis.

Available in both single and dual output versions, WaveCor 5.0 and WaveCor 10.0 synthesizers operate over frequency range of 300 MHz to 5.0 GHz and 300 MHz to 10.0 GHz, respectively. Units provide phase noise levels of -137 dBc/Hz at 10 kHz offset and typical spurious levels of -65 dBc. Switching speeds on both models are less than 200 nsec when tuning to any operating frequency.
