    hi, all
    as you knoe , rf signals level as input are so low ,if i want to
    build a frequency counter that can work for rf signal and ordinary
    output of signalgenarator , should i use different inputs?
    what are the tipical inputlevel of trade frequency counters?
     
  2. My Phillips one is selectable. And as one would expect, there are
    different required minimum input levels depending on which frequency
    range you use. The lowest range is 5mV so that's the sort of level you
    want to be aiming for in a home-made job, I guess.
