PCG10 - consistent function wave output abnormalities

Hi, I just received my PCG10 function generator today from www.apogeekits.com thats ready to use right out of the box. When I finaly got the unit setup, I then hooked it up to my oscilloscope and was surprized to see all the distortion in wave output. The wave follows the selected pattern but there are always short spikes in different locations along the way that are consistent with the abnormalites in the previous cycle. I tried various wave profiles, amplitudes, and frequencies and they all have the same problem with it getting even worse at higher frequencies. Is there a know solution to this problem? what do I do? thanks.

Sorry about the problems and inconvenience with your new PCG10.
There may be LPT port communication problem the reason to the distortion in the waveforms.
You may try lowering the LPT communication speed.
In the function generator’s Options menu select Hardware Setup…
Select “Slow” LPT port communication speed.
