Hi Zack - What I am trying to do is tune a magnetic loop antenna and have the nanoVNA actively track the single lowest SWR across the range as I tune the loop antenna, that would continuously show me

Today, edy555 released a newer version of the nanovna firmware, in which it modified the following: Add format Quality Factor Fix label R+Xj to R+jX Add bandwidth command some fixes You can see beta

Hi Mark, what about this one: https://www.aliexpress.com/item/4000593819988.html?spm=a2g0o.detail. 1000014.11.1dba3346IgYDPz&gps-id=pcDetailBottomMoreOtherSeller&scm=

Hi , just to learning , why not use the short open load and thru already available on the board ? 73 de IZ1MDJ Maurizio

Update to last edy555 code: Now AntScope2 can detect NanoVNA (see my post /g/nanovna-users/message/14317), but this software must better parse info data for correct detect device. A

Solution used in the shop was U.FL adaptors to SMA, then offset the plane of meausrement buy the needed distance in picoseconds. At below 30mhz its not an bit issue. Allison ----------------- No

I think I was using Hugen's but I switched to Edy555's and it seems to be an improvement. Thanks!

Hello David, There was already a longer thtead started December last year: /g/nanovna-users/topic/rf_demo_kit_testing_tutorial/65778338 73, Rudi DL5FA

Any good VNA can be used to evaluate preamps. However, remember to consider IP3 and the max input that may yield 1 dB compression at the output. When driven too hard, the device will not perform as it

Here is the picture. LOL

I purchased an RF Demo Kit (picture attached) that uses SMA to u.fl cables to attach VNAs to a small circuit board with 18 different circuits on it. When I calibrated my H4 using one cable and using

I'm not sure exactly what you want, but my NanoVNA H4 can find the minimum value for SWR or s11, whichever is selected. Choose "Marker" > "Search" > "Minimum" and then "Search Left" or "Search Right."

Yeah, I know. I've designed a lot of preamps optimized for noise figure if the s-parameter file also includes noise optimization files. Generally, the input is not a conjugate match when the NF is

Hi David, Thank you for your answer. In between, i found the "problem". The USB port was connected to a battery powered PC. The NanoVNA's CH0 port was connected to a grounded frequency meter, powered

Hi David, Thank you for your answer. In between, i found the "problem". The USB port was connected to a battery powered PC. The NanoVNA's CH0 port was connected to a grounded frequency meter,?

Have you tried a different USB cable?

Does anyone know of a reasonably priced U.Fl calibration kit? Thanks, Mark

Hello Rudi, The performance of my device was initially very poor. It was one of the early "bad clones" without shields. The S11 at 900 MHz was in the range of -30 dB, S21 -40 dB. So i made some
