In the screenshot I had earlier, the version of the software appeared.
I've tried it again with a newer version of the software, mainly:
PicoScope® 6 - PC Oscilloscope software version: 18.104.22.168
Copyright © 1995-2013, Pico Technology Ltd
Model: PicoScope 6403
Serial Number: AP225/021
USB Version: 2.0
Calibration Date: Tuesday, March 22, 2011
Hardware Version: 1 1
Driver Version: 22.214.171.124
Firmware Version: 126.96.36.199 / 188.8.131.52
And initially, the waveform looks like what the file 0001 has.
After taking the time to write this post, maybe 2-5 minutes to ensure I had everything in order. The signal generator went through a phases of instability (the waveform's amplitude was really acting up) until it started to output the desired waveform, shown in the file 0002.
The files are too big to upload here, so I've uploaded them to dropbox.comhttps://www.dropbox.com/sh/tuzgbkioy77y ... 0SigGenBug
I hope this helps.
