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 intervals. |
