    Has anyone here built a reasonably good curve tracer
    preferably with capability to drive FET's at up to
    200v and 5-10A? I would not mind spending the time
    to build same, if someone has a decent design already
    drawn up. Getting tired of hassling with my kludge :)

    I toyed with the idea several times. Was gonna use a PIC processor
    and do it all in software. Never figured out how to get rid of the
    thermal effects. The current state depends a lot on the temperature
    which depends on previous states. With an analog machine, the
    rep rate is deterministic and you get the same picture every sweep.

    Get the schematics for the TEK 5CT1/7CT1. You'll have to beef it up
    for 10A, but the concept is the same. 576 is even better and already
    does the high volts/amps.

    The concept is trivial. The details for all the range switching, modes
    pnp/npn/fet will drive you ntuz.

    Roger that. Got the concept down. It is definitely the range switching,
    modes, etc, that are driving me "ntuz". :)

    Thanks. Already seen it.
    Not quite what I am looking to do.
