I've now tried to install the remaining programs and examples. when trying to install the bitgen stuff (I have no Idea what it does) I get errors.

I could not actually find this bitlib anywhere. There's a bitscope-library which is installed.(2.0.FE26B)

Got triggering on channel B working after adjusting for DC offset.

Yes, it was too high. I tried again at 1kHz. Signal shape and amplitude look good now.

Try using a lower frequency.

I got one of those. 

Today, I tried to set up two oscilloscope probes.
(the frequency compensation capacitor)
I noticed the following things
in bitscope-dso:

when adjusting the cap, the waveshape doesn't change, but the amplitude does.
at 250kHz it's almost triangles regardless of capacitor setting.
50kHz looks acceptable. I am also not sure what sort of filter it has
and how to turn it off. RF mode on or off looked mostly the same.
Maybe it's an output impedance thing.
Also, I'm unable to start the clock from DSO.
Maybe it has lower Z.

the amplitudes on ch a and b differ significantly.
(have they played with the scope at the shoppe and shot it?)
Also trigger on B doesn't work. A is ok.

and I got two errors:
WARNING: TLCLComponent.Destroy with LCLRefCount>0. Hint: Maybe the component is
processing an event?


I also tried bitscope-logic and got the following:

TApplication.HandleException Index 2 is out of bounds.
