New Style Top Quality 0.01Hz - 2.4GHz Precision Frequency Meter Frequency Counter VC3165

DESCRIPTION :
This frequency counter (VC3165) measures signals over a wide range from 0.01 Hz to 2.4 GHz. The gate time is continuously varying from 100ms to 10s.
All functions in VC3165 depend on a single CPU. A crystal-controlled temperature circuit provides a constant compensation for temperature change, thus reducing measurement errors typically caused by temperature drift. The Channel B (CH. B) input has an attenuator (x1, x20), AC/DC coupling for a low-pass filter.
Frequency, period and equal-precision measuring.
3 step function selections : Work state, Unit and 8-Digit LED display.
