  OR  


Model: VC-3165

 

It is a frequency counter that measures signals over a wide range of 0.01 Hz to 2.4 GHz. Equipped with gate time that is continuously varying from 100ms to 10s and a maximum power consumption of only 5W.

All functions depend on a single CPU. It has a crystal-controlled temperature circuit that provides a constant compensation for temperature change, reduces the measurement errors. Its channel B (CH.B) input provides an attenuator (x1, x20) and an AC/DC coupling.

 

Features:

  • With 3 steps function selection: work state, unit & 8-digit LED display
  • Provides frequency measurement from 0.01Hz to 2.4GHz
  • Provides cyclic measurement range from 0.5ms to 10s
  • With attenuation of 20dB and input impedance of 1MO
  • With frequency, period and equal-precision measurement
  • The machine can switch from 110V to 220V (vise versa)
  • Maximum power consumption is only 5W
