VNA Tools

Hi, no you cannot enter those values directly in VNA Tools. You've to convert those impedance

Hi, I would do it like that: >> a a = 0.8147 + 0.6324i 0.9058 + 0.0975i 0.1270 + 0.2785i 0.9134

Hi Michael, Excellent, many thanks for your help. Best regards James On Monday, January 9, 2023 at 3:

Hi, can you please upload your calibration standard definitions which you used. I'm pretty sure

Dear Michael and VNA Tolls developers, Thanks for all your support in this group. I my opinion, as

I would like to explain that with the following example in MATLAB. For reason of simplification I

1. You need Visual Studio code, see https://code.visualstudio.com/ 2. You need CPython, see https://

Dear Claes, cable influences are not an easy topic and how to minimise them are discussed in detail

Thank you very much Michael, the problem is solved after installing NI-VISA. On Wednesday, November

thank you. modifying the analyzedrift script worked great! On Monday, November 7, 2022 at 4:57:25 AM

Hi, this a bug introduced in VNA Tools V2.6.0. Cable files created with VNA Tools V1.7.0 to V1.8.2

Hi, see the VNA Guide, Appendix G.3 https://www.euramet.org/Media/news/I-CAL-GUI-

Hi, you could write a text file with 3 columns (frequency, value and uncertainty), see https://www.

Thank you, this is helpful. I did have the Small Unc Limit set to 0 from the training. I'm using

Hello, When characterising a test port adapter, does it make a difference whether one calibrates

I have seen latest Version 2.5.7935.30849 can support Frequency Conversion Calibrations(3.9.1 Scalar

I keep making incremental progress on this methodology, Michael, but progress nonetheless. Using

Hi, this is bug introduced in V2.5.2 of VNA Tools. There is workaround for it, see see https://groups

Hi, LRRM_Opt_01.calcfg needs QSOLT_01 as start values for the optimization. LRRM_Opt_01.calcfg is

Good news, Michael. I was able to save the impedance states as databased standards and refer to them

This could be due an unhandled exception when VNA Tools loads the user.config file: Unhandled

The power sensor and the VNA sweep is measured with Metas.Instr.Driver.Vna.VnaHelper.

Hi, The fix works. Thanks for the suppport. Regards Claes RISE, Research Institutes of Sweden tisdag

Hi, this is not possible at the moment with a GSOLT calibration. This is a limitation of VNA Tools.

The Linearity tables are empty for your defined VNA. See Database / VNA Device / Linearity. See an

Thanks, Michael. 'LoadSParamDataAsStruct' works fine. On Monday, April 4, 2022 at 11:35:24 PM

Thanks Michael for the script. Works perfectly fine. Best regards Simon Michael Wollensack METAS

Hi, your conversion looks right, see https://www.wolframalpha.com/input?i=D%5B20*log10%5Bx%5D%5D
