DDS-based Programmable Oscillator Module
Model PCK-80 |
PCK-80 is wide band clock source utilizing Direct Digital Synthesis technique. It
provides CMOS/TTL level clock output from 1Hz to 80MHz in 1Hz step. The
frequency can be controlled by parallel data such as DIP SW or async serial data
which can be connected to PCcommunication port. PCK-80 can be used for both
digital clock source and signal source in communication system.

OPTION Frequency setting board FIX-80 |
Frequency setting board FIX-80 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.
