VNA Tools

Hi, thank you for your quick answer. Actually, this is some kind of stupid mistake, but i will learn

Hello, I have a question about S21 uncertainty calculation. VNA tools calculate automatically, but

The copper mountain driver implemented in VNA Tools was not developed by METAS. Therefore please

I'm not sure how precise value You need. You can try use 3dB atteuator with short at the end as a

Looks fine now ! However the structure I want to get rid of is in the negative times. Do you know why

Hi Cecile, > I want to check how big is the influence of Primary Calibration Standard, so I

Dear Micheal Thanks for your reply. I couldn't find time to fully try the workaround yet but for

Michael, Didn't see the update and had already modified the driver to work. I will replace with

Hi Fabian, the TRL calibration works only with two ports. Se as well Math Reference of VNA Tools.

Hi From time to time I have to measure the impedance (Z11) of devices with very differing connectors,

Hi, the attached Python script will convert the sdatb files from all "_out" folders found

The additional files allowed us to find the problem ;-) There is an issue in the root path definition

Hello, I have used VNA-Tools II "Fit Calibration Standard Model" function to analyze

Hello Erkan, Our lab using VNA-Tools II with Flann Microwave WG kit's and it working well (One

Great! Thank you very much for your help. The connection test was successful now! Best Regards Patric

Hi, you get a negative VSWR when the absolute value of your reflection is larger than 1. Regards

Hi Juerg, You are right the differences between the CMC and actual uncertainties are very small. I

Hi, your Firmware of your PNA is very old. It still version 6 branch. Keysight changes some of the

Hello %, I would like to use prerecorded measurement and simulation date to be evaluated with the VNA

Dear Jose Manuel, the new release 2.3.1 is now available from our website. Release notes: https://www

We recently got a request how the 1-port measurements de-embedding technique can be done using VNA

Hi Michael, I understand that. This was more to simplify the analysis of what I was seeing. Since the

Hello, By single S-parameter Like S11 , we can visualize the measurement uncertainty it's work.

Hello, We install recently the VNA tools version 2.2.7220.27700 , we only find the Cal Kit 85033D is

Hi, no that's not possible. At the moment it characterize the noise for all ports and takes the

Hi, thank so much for your fast response. I untestood that with VNA Tool I already installed LinProp.

Hi Michael, Finally had the time to verify this... had to use a single backslash in the path
