Network Analyzer - Smith Chart

[amiclaus]

Based on reviews, some people might prefer using the Smith Chart for data visualization.

Is this a reasonable feature that can be implemented?

Looking at the schematics and network analyzer code I would suggest splitting this into two different instruments:

• a Vector Network Analyzer for two-port measurements with a Smith Chart display
• transfer function plotter for the already implemented behavior with logarithmic charts

The VNA could put the hardware into the DAC calibration configuration in order to make the connections neater and avoid needing to figure out which ADC is connected to which port. Just did the math, that would limit it to about 1Mhz. Additionally it would necessarily work as an impedance analyzer, just a little bit of math on the reflection coefficient.

That being said, I would appreciate an option to use that calibration path for measurements; but that might be a separate feature request.
