[Lowfer] Post Capture Processing (was: XSR in CT)

Mike,

    Another (and easier) way to control the HP-3586C is with an RS-232-to-GPIB
external interface.  You can find them on eBay designated GPIB-232C-A  There is
extensive documentation for it on the National Instruments website and I find it
much easier to use than the GPIB XT card.  Eats up a serial port but not a card
slot ...
