    Hi all,

    I have a signal which I need to measure during fabrication. The signal
    is a 2.88 MHz crystal and I need to know the signal level and

    A scope is a great device to do this but I really only need a display
    with frequency and signal level.

    A frequency counter would do the trick for the frequency measurement
    but can not locate one of these with a signal level indication.

    Any thoughts?

  2. Two thoughts:

    1/ Crystal oscillators work or they don't. Why is amplitude an issue?

    2/ If there is some possibility that any given circuit oscillates but
    perhaps at too low of an amplitude, you could come up with a simple
    attenuator for the input of your counter that would not allow the
    sub-standard signal to produce a stable reading.
