It is a high-resolution multifunction intelligent frequency counter based on microprocessor.
Features include frequency, period and equal-precision measuring. Also, 3 step function selection,
work state, unit and eight-digit LED display. All function depend on a single CPU. A crystal controlled
temperature circuit provides constant compensation for temperature change thereby reducing measurement
errors typically caused by temperature drift. The CH.B input has an attenuator(X1,X20), &AC/DC coupling for
The instrument measures signals over a wide range from 0.01Hz to 2.4GHz. The gate time is continuously
The instrument provides high performance stability, & function at a low cost.
