Useful for testing two way radios for frequency measurement in the field or using on the bench, the M1 is a full range 50Hz-2.8GHz frequency counter. Using an embedded micro-controller along with our powerful custom OE40 counter IC, the M1 provides advanced features such as our Patented Digital Auto Filter, Digital Auto Capture and Data Storage. The M1 BNC input may be switched from 50OHm to 1 Meg OHm for use with a scope or low pass audio probe for in-circuit measurement of test points and oscillators.

TCXO Option

The M1 has an optional high stability .5ppm TCXO timebase. This is twice as stable over time and temperature than most frequency counters.

PC Download and Datalogging

The M1 is equipped with an PC interface port that allows the unit to be interfaced to our Optolinx for the purpose of real time datalogging and downloading of frequencies in memory. The new OptoSuite Pro software is also required. (Optolinx and OptoSuite Pro sold separately)
