Frequency setting board FIXPCV-50F

Frequency setting board FIXPCV-50F is able to 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.

PCV-50F is wide band clock source utilizing 48 BIT Direct Digital Synthesis technique. It provides CMOS/TTL level clock output from 0.001Hz to 50MHz in 0.001Hz step
with any external reference clock from 7MHz to 50MHz.
The frequency can be controlled by parallel data such as DIP SW or asynchronous serial data
which can be connected to PCcommunication port. The accuracy of the output frequency
depends on an external reference clock.
