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


Specifications:

  • 8 digit LED display
  • 3 step function selections
  • Channel B (CH. B) input has an attenuator (x1, x20)
  • AC/DC coupling for low-pass filter
  • All functions depend on a single CPU
  • Crystal-controlled temperature circuit
  • 2 Input Channels : Channel A for 0.01 Hz to 50 MHz ; Channel B for 50 MHz to 2.4 GHz 
  • Channel A (0.01Hz to 50 MHz) 
    • Frequency range : DC couple 0.01 Hz to 100 Hz ; AC couple 100 Hz to 50 MHz 
    •   Sensitivity :
      • "DC" 0.01 Hz - 1 Hz = 500m Vp-p , 1 Hz - 100Hz = 80m Vrms
      • "AC" 100 Hz - 50 M Hz = 80m Vrms
    • Input impedance : 1 MΩ
  • Channel B (50 MHz to 2.4 GHz) 
    • Frequency : 50 MHz - 2.4 GHz 
    •   Sensitivity :
      • 50 MHz - 1.2 GHz = 80m Vrms 
      • 1.2 GHz - 2.4 GHz > 80m Vrms 
    • Coupling : AC only 
    • Input Impedance : 50Ω
  • Resolution depends on gate time control setting
