Hello all I am finally on board with you. Looks like I know most of you TEFers.
I had my first problem with a TEF 25 and/or laptop last week. During the sweep there was a significant distortion, buzz or sawtooth waveform sound riding on the sweep. I eliminated the sound system as the problem on site by using a handheld battery powered Neutrik Signal Generator that sounded clean. (Although it could be an AC power grounding thing I guess.) Called GoldLine from the site but never got through. Maybe a holiday week off.
I haven't got to troubleshootong in the lab yet but will this weekend or Monday afternoon. I wanted to go ahead and post this so I could get ahead of the game. Anyone seen this before?
Plans are to use another computer to confirm the TEF 25 and also look at the signal on an O-scope. I have tried several USB ports on the laptop with no change.
Thanks for any insight.
