Fiddling with my CWAV AX clone, I see that there is a lag of about 6 us between the analogue channel and the digital channels in PulseView. Analogue is behind.
(Or around 4 samples at 500 kHz / around 2 samples at 200 kHz). Maybe a "user definable offset" can fix this.
It's assumed that the skew is a property of the hardware in the capture device
(very probably the ADC). The software reflects the samples in the very way
they are available from the FX2's perspective.
It's uncertain how generic an issue this is (applicable to _any_ mixed signal
acquisition device? to arbitrary input files as well?). I'd suggest to
capture to disk, and optionally postprocess the analog part of the capture,
before loading the file for subsequent inspection. This might be as simple
as dropping the first few bytes of the first/only analog chunk, and padding
the last/only, to "shift" the analog trace by a desired amount of sample
