Frequency display help

  1. Mar 27, 2006 #1
    Hell oI am trying to find a pre-made frequency display module that I connect to a transistor for oscillation reference.
    Does anyone know a good place to get a cheap one.
    Im only a car audio tech so i need something simple.

    How high of a frequency? Some DVMs like a Fluke 87 have this built in already and is good to 200KHz.
