Precision Frequency Counter Meter Recorder VC3165


Always Free Shipping


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.

Question & Answer:

will this work like the Hand Portable Versions that can put an Antenna on it to get a Frequency?
e.g. CB Radio, by the Transmitter to Display the Frequency being transmitted

Yes, you could put an antenna on VC3165 to get a frequency, but it is not easy to realize, the single brought in by the antenna should meet the input feature of VC3165.
