    If it is for thr Audio range, you can use a software (cool edit or similar)
    to create test tones and burn them on a CD or play them with a soundcard.
    Much easier and cheaper with better quality.

    How about signal generator feeding squaring circuit (comparator) which
    generates count-down-clock which opens and closes analog switch to
    original signal (as programmed)?
