The M1 is the latest advancement in hand-held frequency test instruments. It excels at finding and record-
ing frequencies for security, law enforcement, commercial and recreational applications. Patented tech-
nology developed by Optoelectronics employs statistical analysis to filter out actual radio transmission
frequencies from the background RF.
The M1 is more than a test instrument in the traditional sense because it is useful for finding frequencies
being used for two way radio communications. Designed to work with an antenna to pick up transmitted
radio frequencies, it is actually a frequency recorder. Up to 100 unique frequencies can be stored in mem-
ory. For in circuit measurement of frequencies from oscillators or test points, the 1Meg input impedance
amplifier can be used with a scope probe for direct connection to test points.
The counter circuitry produces a coherent and stable count when there is a single dominant signal 10 to
20 dB stronger than any other signal or the RF floor. An embedded microprocessor evaluates each mea-
surement statistically to determine when an actual RF frequency is dominant. This is the digital filter pro-
cessing which makes automatic capture and recording possible.
The M1 includes an AC-90 power adapter.
