Product Information

50MHz Frequency Counter Module with programmable IF Offset.

Fully built and calibrated (not a kit)

This module is a highly flexible frequency counter that incorporates programmable IF offset (parameters are stored in nonvolatile EEPROM). Its small size allows it to be incorporated into your own equipment and your battery will hardly notice its modest current requirement. A input buffer isolates the counter to minimize loading of the signal source. The 16 character back lite LCD display (white text on blue background) is easily viewable over a wide angle in modest lighting conditions. Operation is as simple as connecting power and a signal source.
