Is there a wiring error in the Network Analyzer manual section?

Not sure where the appropriate place to post this is, but it seems like there's an error in the Using the Network Analyzer manual page.  It looks like Ch2+ is connected to the input of the RC filter and Ch1+ to the output, so the two have been swapped.  This seems to be confirmed by the plot shown further down in "Run the Network Analyzer", in which C2 is showing the flat input while C1 is showing a response curve, even though the small diagram on the top right of the image shows C1+ at the input and C2+ at the output.

Or am I misinterpreting something there?

Hi @fizzbang

The default reference channel in the application is Channel 1 but this can be changed under Phase / Ref
It is mentioned in 2.2 "set the phase reference to channel 2" https://digilent.com/reference/test-and-measurement/guides/waveforms-network-analyzer

Sure, I realise you can compensate for it but was more concerned that there appeared to be an error in the documentation that might confuse some people.

Hi @fizzbang

Thank you for the observation.

@JColvin probably knows who the editor of this guide is.

I will see if I can schedule some time to rework the guide and associated screenshots to make the guide more intuitive (meaning using default options rather than customizing the setup in this getting started guide).
