2.5 GHz Frequency counter
This project describes a very powerful frequency counter.
Very simple construction which everyone can build.
6 LED display will present the frequency with 1kHz resolution and
RS232 communication to computer is available as option.
The software has also been implemented with some smart functions,
for calculating frequencies in receivers where IF is 455kHz or 10.7MHz.
I present schematic, PCB, components and window software.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
