Victor Precision Frequency Counter 0.01Hz to 2.4GHz Digital RF Meter

Frequency counter that measures signals over a wide range of 0.01Hz - 2.4GHz. Gate time that is continuously varying from 100ms-10s. 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.
Features
* Switch from 110V to 220V (vise versa)
* 5W max consumption
Specifications
8digit LED display
3step function selections
Channel B input has an attenuator(x1,x20)
AC/DC coupling for low-pass filter
2 Input Channels: Channel A for 0.01Hz-50MHz ; Channel B for 50MHz-2.4GHz
Channel A (0.01Hz to 50 MHz)
* Freq range: DC couple 0.01-100Hz ; AC couple 100Hz-50MHz
* Sensitivity: "DC" 0.01-1Hz = 500m Vp-p, 1-100Hz = 80m Vrms, "AC" 100Hz - 50mHz = 80m Vrms
* Input impedance: 1 M
Channel B (50MHz - 2.4GHz)
* Freq: 50MHz - 2.4GHz
* Sensitivity: 50MHz-1.2GHz = 80m Vrms, 1.2-2.4GHz > 80m Vrms
* Coupling: AC only
* Input Impedance: 50
Resolution depends on gate time control setting
