Dear Sir / Madam,
I have been using the PicoScope 3204 for a few months but had this problems since the beginning:
a) Frequenctly, it false triggers (triggers at the right level but opposite slope). This is especially true with voltage ranges of +/- 1V or lower. The ratio of false to correct triggers is variable, quite often 50%, which makes the signal jump between the two slopes.
For the same signal, the problem goes away if the voltage range is +/- 2V or higher. Tried modifying all triggering and sampling parameters without any luck.
I have some sample PSD files, but I don't see an option to add an attachment on this form.
b) Although connected to a USB 2 port with a USB 2 compliant cable, the OS always indicates that the "device can perform faster if connected to a USB 2 port".
Could this be a faulty unit?
