Frequency Synthesizer Model : DPL-4.2GF
DPL-4.2GF is a frequency Synthesizer which can generate any frequency from 50MHz to 4.2GHz ,
utilizing PLL technique(Phase Locked Loop)in 1Hz step.
It can be used as a clock source or local oscillator for any application because of its excellent phase noise and low spurious level.
When a sine wave is needed, low pass filter should be attached for removing harmonics.
The frequency can be set not only with asynchronous serial data but by SPI serial data.
USB Interface adaptor is available as an option.
