home made counter scope preamp
« on: June 20, 2013, 10:47:42 AM »
You can use this circuit for you scope or counter. It is a preamp that works fairly good as a sniffer circuit.
Build in a metal box with a 9 volt battery, toggle swith and a 3 inch piece of coax as a probe. Connect to counter and read the oscilators without connecting them.
