Finally got around to making my limp jig and start measuring.....and of course issues.
Following Hong's thread on PETT and I'm not getting what he is showing. I get V-Fib and that's it. No smooth-two-graph response. I have sound from the speaker, appears to be wired correctly..... but just a crazy squiggle that appears to represent Phase (it seems to be centered around zero for phase)
I've clicked M+P, PN Pink, calibrated with jig connected but speaker not........
What am I missing?
