Exclusive 2.5 GHz Frequency Counter
This project explain a very powerful frequency counter which has many useful software functions.
The software can add or subtract 3 different IF frequencies (455 kHz ,10.7 MHz and 21.4 MHz).
You have also two level of resolutions, 1kHz and 100Hz. The main oscillator can be on-board 13MHz or external 10 MHz.
The counter data can easy be transmitted to computer with RS232 cable.
