Bitscope (Micro BS05) and 32bit Linux

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. Stack trace: $082AF567 $082AF802 $08240105 $082BC82B $08118DBE $082BBCB9 $082B4C68 $080A4C02 $0809F582 $0809F9BF $08236436 $0809E0C6 $08091B0C $08093173 $08214D45 $081FA975 $08208099 WARNING: TLCLComponent.Destroy with LCLRefCount>0. Hint: Maybe the component is processing an event? An unhandled exception occurred at $00000000 : EAccessViolation : Access violation $00000000 $080EDB31 $0806B1C1



Try using a lower frequency.

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

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

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)
