Run analyzer on an analog channel

I'd like to be able to simply select an analog channel to run an existing protocol analyzer on. It would effectively convert the analog data to digital data and run the analyzer as-is, support for analyzing analog data would be even nicer but a much bigger change obviously. Ideally it would be possible to specify the 0 and 1 thresholds for this analog-to-digital conversion (with hysteresis and/or glitch filtering), so that you could analyze signals that are at voltages other than 1.2V/1.8V/3.3V more accurately.

"I am trying to write a low level analyzer to decode an FSK radio signal that is down converted to 100KHz. I was able to build the SampleAnalyzer project and was able to start working with it. I want to work with it as an analog signal instead of a digital one. I was able to modify the AnalyzerSettings to select the channel I want but when I do it automatically adds the channel as a digital one. Is there a way to select the channel as analog?"

High-speed CAN is a good application for this. The physical layer is a differential pair with an offset around 2.5 V.

I would like to use this feature to decode an ARINC 429 commercial avionics bus. The physical layer is differential and looks like this.
