DDS-based Programmable Oscillator Module
Model PCK-820 |
PCK-820 is wide band clock source utilizing Direct Digital Synthesis and Phase
Locked Loop technique. It provides any frequency output from 1MHz to 820MHz in
1Hz step. The frequency can be controlled by parallel data such as DIP SW or
serial data which can be connected to PC communication port. PCK-820 can be used
as a programable VCXO by external control input.

OPTION Frequency setting board FIX-820 |
Frequency setting board FIX-820 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.
