Thank you, I'm sure they do. I might try the software out eventually, but I don't have the meter connected via USB; it's only connected via LAN.
I do like the graphs that come from the analyzer. It's interesting to see the frequency sweeps. It seems to me that it makes the valid test frequency range more obvious. The funny thing is that I thought it was slow, and then I remembered I have avg set to 16 still, and apparently that carried over to the analyzer. Next time I'm going to try either less samples, or no averaging and see how fast the sweep from 20Hz to 5MHz goes.
Have you seen the IM9000 firmware option? That's also interesting, with more plot types available. I don't have that option currently.
