    How to get two Sweep and Repeat Generators in sync.

    What is the best way to make a sign wave shift frequency downward only about 10 Hertz, then repeat every .2 seconds.
    The initial frequency 3000 Hz.
    There will be 2 generators sweeping, both will be in sync (repeat at the same time).

    See attachment for drawing.

    Depends on the generator. Popular arbitrary function generators can sync their sweeps through trigger out and sync in jacks, e.g. Agilent 33220A.

    Many types of oscillators change frequency if you change supply voltage. Or you can 'bend' an RC time constant by changing a resistance somewhere in the circuit, or by applying a voltage at a strategic node. Many oscillators have their frequency determined from an RC time constant.
