OPTION Frequency setting board FIX-50

Frequency setting board FIX-50 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.

PCK-50AF is wide band clock source utilizing Direct Digital Synthesis technique.
It provides CMOS/TTL level clock output and analog output from 1Hz to 50MHz in 1Hz step.
The frequency can be controlled by parallel data such as DIP SW or a serial data
which can be connected to PC communication port. PCK-50AF can be used for both digital,
analog and RF signal source.
