    that looks like one of the fixtures TEK sales engineers used to be given
    for demos,not a catalog item.
    They had some neat demo circuits for scopes.Stuff that generated "runt"
    pulses,very low duty cycle pulses,"glitches".

    Perhaps, but was it used to connect two inputs together?

    I have such a gadget. It just takes it's power from the Tekpropbe
    interface and the small box has a CMOS oscillator with some 'edge
    enhancement features' to demonstrate some of their scopes' advanced
    trigger functions.

    those are not just "inputs",they also OUTput power to what's connected to
    the 1103,that have the extra contacts built into their "BNC".
    This system does not require the extra probe power cable and LEMO
    connectors as the old 7000 series had.

    the fixture uses the 1103 DC power to generate a signal for the 2465.
    (which does not have probe power capability)
     
  5. But just verifying the presence of probe-power doesn't
    test the circuitry of the 1103's four input controls.

    Sometimes they took empty FET probe pods from stock and built generators
    and stuff into it which in turn inject the desired wave form into a
    scope inputs. Just like us guys occacionally take a ballpoint pen, scrap
    its guts out and put an "RF noise maker" into it. You'd be surprised,
    today's college kids sit there with their mouths wide open when I am
    using something as simple as a pocket size signal injector and find out
    within a few seconds which one of their amp stages ain't working. "What
    on earth is that thing?" Ok, on that one I cheated, bought it for around
    $5 from a hobby electronics place in the 70's. The days when people
    still repaired their radios instead of throwing them away.

    Of course, for field demo purposes I'd have used someting with an AA
    battery in there. Much easier to travel with. Well, maybe not nowadays
    with the new TSA rules.
