| You want? You go out and buy one! Forget building one for that range. Stop dreaming - get real :lol: Klaus | |

| high-frequency counters As tanveerriazs' post shows, you can build a frequency counter to cover this range if a suitable prescaler is used on the front end. Finding appropriate test leads is another matter that deserves close attention, as does the PCB layout of the prescaler section. Schematics leave out some important details, physical layout is critical at these frequencies. | |

| You need a prescaler or freq. divider, but before you do that you must first insert the analog signal into an schmitt trigegr (hope spelling is rigth). After that use windowing theory and latch the reading. Glenjoy | |
