I went to radio shack and bought a bunch of bnc jacks of various types, and attached the business end of a patch cord to one of them. I also made a homebrew probe by taking a switchcraft jack and attaching wires terminating in alligator clips to the appropriate terminals. With these 2 tools, I'm covered. Note - this is NOT what people who know what they're doing do necessarily - consider the fact that i bought my scope on ebay for 21$ (a nice, fully functional heath). Whenever I visit any of our local electronics stores, I contemplate buying some real probes, but then contemplate having a few extra dollars left over, and pass.

I finally sat down tonight at got my Tektronix to give me some
waveform views of one of my oscillators. There was more than a little
trial-and-error at first, but once I got in the ballpark I was able to
zero in on clear, static waveforms that changed shape in predictable
and expected ways, which was immensely satisfying (and will no doubt
impress my musical buddies, for whom a MOTM cabinet is already like
seeing something out of Close Encounters - this now adds that last mad
scientist touch).
And I got the onboard frequency counter working, which is a nice plus.
All this was done using a rather painful method whereby I clipped the
ground to one exposed terminal on the end of a phone cable and touched
the probe to the other. While this worked, it was not at all easy to
do one-handed, and clearly not a long-term methodology. What I really
want is to make this kind of connection permanent, ie just have some
sort of probe terminating in a phone plug that I can tap into any jack
without worrying about fiddly connections. Does such a thing exist,
either ready-to-use or in some combination of probes+adaptors?
What do people who know what they're doing do? (he said, and not for
the first time...)
Thanks!
