DDS-based Dual Channel Programmable Phase Generator
Model PPG-20 |
Utilizing Direct Digital Synthesis technique, PPG-20 can generate
two sine waves from 100Hz to 20MHz in 1Hz step with any desired
phase difference. PPG-20 can be used for stand-alone dual channel
signal source. The output signal amplitude can be varied from
0.1V to 1V in 1mV step.

OPTION Frequency setting board FIX-20 |
Frequency setting board FIX-20 can be set frequency easily with BCD switches.
A frequency and setting value can be memorized with a save switch on the board.
When the module is used for itself, it is used as a memory setting tool of the parameter.
Just insert the module to the sockets of the board. Also, the detaching is easy.
