Bad squares on 2204A AWG ?

Post by Clemens Johansen » Thu Apr 11, 2019 8:01 pm

I'm somewhat disappointed by the square generator in the PicoScope 2204A.
Please have a look at the attached 50 kHz sample. :The red channel is the PicoScope AWG; the green is an old Velleman generator (originally designed for Win 95 or -98. Here it is run on Win XP probabely causing the overshot).
What do you think?

The rise time specification (10% to 90%) for the generator is < 2 μs which matches your document and my testing.
