Frustration

(As I named this post I realized this is the fifth post with that title so far... I guess there's a trend.)Today I had a good day at work. I worked out beforehand. I gave blood. I solved problems, both my own and helping out other folks. Not frustrating.I get home and I run out to Fry's to grab some components and connectors. I lacked a BNC patch cable and I wanted a few odds and ends. No problems there either. Other than the chilly ride it was completely uneventful.I get home and plug the scope's input into it's function generator output on the back with my new BNC patch cable. I futz around and try stuff out... then I notice a problem.If you look close you can see that the setup for the AFG (Arbitrary Function Generator) is a 100 kHz sine at 100mVpp. (0.1 Volts peak to peak -- or 0.05 V plus and minus)If you look at the actual that's on the scope you'll see about 5 Vpp (2.5V +/-) if you look at the 2V/division graticule. I added a peak-to-peak measure that's showing 2.66Vpp reading. I cross-checked this with a multimeter that has the bandwidth and it too agrees with the reading.So I go to look over at my computer that's to the right of me and it's tilted way forward to where I can't use it. I try to move it back up to where it should be and it quickly snaps back to where it's unusable. I Google around and this seems to be a common-ish problem.There's nothing quite like problems on top of problems to rile you up.<sigh/>All under warrantee, but it's a fucking hassle.
