Additinal analysis methods added / better peak search algorythm
try to read initial frequencies
Fixes #165 - Allows for both |Z| and R + jX display - Measurements of shunt impedance (accurate for low impedance values) as well as series impedance (accurate for high impedance values)
Added measurement graphs showing impedance measured via S21
401 sweep points
New test version
Adding support for |Z| plots with logarithmic scale and some cleanup
The various models of VNAs supported by NanoVNASaver support very different frequency ranges. Make the maximum stop frequency for each model available as an attribute so we can use it later on. The settings are based on information from: - AVNA: http://www.janbob.com/electron/AVNA1/AVNA-UsersManual.pdf - NanoVNA (v1): https://www.dropbox.com/s/0t1ms1y0uyaa90s/NanoVNA-a1-20170115.pdf?dl=1 (linked from https://ttrf.tk/kit/nanovna/) - NanoVNA-F: https://github.com/flyoob/NanoVNA-F - NanoVNA-F V2: http://www.sysjoint.com/pdf/NanoVNA-F%2520V2%2520Portable%2520Vector%2520Network%2520Analyzer%2520User%2520Guide%2520V1.0.pdf - NanoVNA-H: https://nanovna.com/, https://item.taobao.com/item.htm?id=588815021483 - NanoVNA-H4: https://nanovna.com/ - NanoVNA V2: https://nanorfe.com/nanovna-v2.html
As of firmware version 1.0.2 (tag 20210214) the output power of the TX ADF4350 can be configured via USB (register 0x42). Add support for this setting in NanoVNASaver. The SI5351 does not support setting the output voltage / power (only the maximum current which controls rise / fall time rather than output power) so we can only affect frequencies from 140MHz up. Clearly show this in the UI so there are no surprises. Because we can only detect this capability by talking to the VNA, the setting is populated during connect. *WARNING*: The automatic first sweep after connecting to the VNA will be performed at maximum power (default). Sensitive equipment should not be connect until after NanoVNASaver has connected to the NanoVNA v2 and the setting has been changed.
Resolves plotting issue as discussed in #165
Add support for setting TX power on NanoVNA v2
Fixing minimum axis label value in RI charts
Add new s21 markers for |Z| and R+jX
