Frequency counter RF 0.01 to 2.4 GHz

This is a universal frequency counter module with the possibility of displaying the real frequency or an adjustable IF frequency in the range 0 to 99.9999 MHz, and can be set to increase or decrease the IF frequency mode. There is a temperature-compensated voltage-controlled crystal oscillator (2.5ppm VC-TCXO), a unique gate control, and a precise timing algorithm (non-timed interrupt).

Gate (display refresh) time is selectable at 0.01, 0.1 or 1.0 seconds, with real-time display of the frequency value. The input channel is automatically selected as high or low based on frequency, with a decision point at 60 MHz.
