Znb read from existing channels

[jenshnielsen]

@QCoDeS/core This enables reading channels that are already mapped on the ZNB from a manual user config. This is sort of a stop gap solution because we cant fully setup everything with the driver yet.

So I would much prefer to have this done in a proper way but I think this is good enough to be useful. And I have a hart time seeing how we would get enough bandwidth to implement all the functionality needed to setup more advanced channels on the ZNB without relying on using the front panel. @QCoDeS/core What do you think?

[astafan8]

I agree with the incremental approach here due to the complexity of the instrument.

Big thanks for reworking the notebook!!!

Minor comments on the notebook:

• perhaps it can be executed with a new db file so that there is no long list of measurements at the top of the notebook))
• in17 - not full_trace but trace_mag_phase if understand it correctly?
• in40 - is the warning there by intention? it does not seem like so.

[Dominik-Vogel]

I think that looks very sensible. If you feel in the mood for it you could add an example for the trace_mag_phase parameter.

@astafan8

• Yes, fixed
• Yes that parameter changed name at some point and the notebook was not updated
• Added the rf on and cleared the warning. I don't have the instrument any more. So I did not rerun

@Dominik-Vogel There is an example of that in [17] as far as I can see
