True, however, I was thinking forward as I understand a 3 channel nano receiver is under development. Further, the technique for obtaining true 2 port s data currently requires unbolting the test

TRL calibration requires a VNA with 4 receivers. The HP 8753 series, which have 3 receivers, can perform something HP refer to as TRL*. This requires a good match at the test ports - typically 6 to 10

The best way to do this is to perform a calibration then measure the properties of a very good transmission line shorted at the end. The amplitude should be constant with frequency. Errors will cause

Unfortunately setting the delay after calibration with DISPLAY - SCALE - ELECTRICAL DELAY menu. will not give good results for many connectors - in particular for N connectors. The reason is because

Some of us have commercial cal kits for which C0 (as well as C1-C3) and the delays are specified by the manufacturer. In my opinion, C1-C3 are unnecessary for the NanoVNA's frequency range, but it

The group has been focused on SOLT or so called SOLM (match) for calibration. However, for various reasons the TRL; Thru, Reflect, Line calibration algorithm would be advantageous. Fabrication of such

More on getting started, I have a laptop fine, can the Saver be downloaded to a Kindle Fire for portable use? Just a question. On a ladder in the antenna range the Kindle is a lot smaller. -- Mel,

you already can setup delay with DISPLAY - SCALE - ELECTRICAL DELAY menu. If you needs C0 settings, just explain me how to test that it works properly? I will add such settings if it really helps.

Nice enhancement.I'll add this to my Console command document, specifying your version of firmware. Regards,Larry

NanoVNA already uses STM32F072CB which has 128 kB flash and 16 kB RAM. NanoVNA uses end of 128 kB flash block to store configuration and calibration data. So, if your NanoVNA can store and restore

The speed which you set for NanoVNA COM port doesn't matter. The speed value is just not used. No matter what speed you choose, it always communication at maximum speed. :) If you have trouble with

Fantastic!!! This opens up the possibility of a whole new round of firmware-based functional enhancements for this device. Thanks for the effort. It would be great if you could upload a few photos of

yes, exactly. The price is inadequate very expensive. The real price for such board is 2-5 usd. But they sell it for 30 usd, this is crazy price for the bord with just a connectors with no elements,

I have successfully ported the NanoVNA firmware to support STM32F303CCT6. The detail can be found at https://github.com/AA6KL/NanoVNA The minimum required hardware mod is to replace the MCU and add a
