    I bought a used Subject scope 10 years ago and really never used it,
    except to try it for simple tasks. It was probably beyond what I needed,
    but I knew the seller and the price was right. Time to sell it.

    I'd like to know if it actually works before selling it, but have long
    forgotten whatever I needed to know on how to operate it. I have
    function generator, and plugged the BNC connector from the scope into it
    yesterday. I was unable to get any signal on the scope. I know the
    generator works. What are the simplest steps I need to perform to get
    some signal displayed? The gen is a BK Precision 4011 5MHz.

    If it's anything like the TEKTRONIX 465B that's sitting on the workbench
    behind me as I type, when you switch it on, does the "power" LED indicator
    light up? If so does either of the volts/div range switch LED's on
    channel 1 or channel 2 light up? If not, switch on push-button marked
    "ch1" or "ch2" and twiddle the respective "position" knobs until the beam
    comes into view. Or push the "beam find" button. Either way, when you've
    got a trace on the screen, make sure the timebase range selector is set to
    a range appropriate to the frequency you're providing from your genny, and
    the volts/div range selector is set appropriate to it's amplitude.
    HTH.

    Cheers,
    Pete.

    Also make sure that you switch sync to 'auto' so it displays a trace
    regardless of receiving a signal or not. In addition to the suggestions
    above, use the horizontal position control if the trace is mispositioned.

    Some sciopes also have a 'component tester' mode which disables most of
    the other controls, but I doubt this is a problem with your model :)

    Let us hear how it worked..
