M1

Details

The M1 from Optoelectronics is a useful tool for testing two way radios for frequency measurement noth in the field or on the bench. the M1 is a full range 50Hz-2.8GHz frequency counter. Using a buit in micro-controller along with the 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 Optional

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