The M1-TCXO Frequency Counter TCXO FITTED, 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 FITTED

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