VC3165 Frequency Counter .01Hz to 2.4GHz with 8 Digit Display

The VC3165 frequency counter measures signals over a wide range of 0.01 Hz to 2.4 GHz. It is equipped with gate time that is continuously varying from 100ms to 10s and has 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, reducing 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 be switched from 110V to 220V (and vise versa)
• Maximum power consumption is only 5W

• 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
