Ouch, the toggle switch between the outputs? Inconvenient to say at least. I would hope you find a better switch than this one it is to easy damaged especially in the position it is in. Will you be

Good morning GIN&PEZ; To the extent that I can contribute in some positive manner, I am certainly willing to do so under the careful scrutiny of your editorial council to prevent propagating

Shields will only show performance in a RF environment, if your lab is clean, you will not notice anything. So keep the shields in place, please. Going to become a VolksVNA. OE8UWW

I was wondering about that als

There are little sensible specifications on the raw performance. The match at port 1 is significantly better than port 2. As for dynamic range, there should be two figures for that - a system dynamic

Here are the final pre-production prototypes, and plots showing uncalibrated and calibrated S21 floor. PCB files will be released when V2 is available for order. The LCD connector can accept the 4

One thing I do not understand is why connecting the port 1 and 2 grounds together should decrease performance. Shouldn't all grounds be connected together, and all of these grounds to the chassis?

Here are plots before and after calibration.

I'm pretty sure S11 directivity is a well defined parameter. It is the (uncalibrated) ratio between the |S11| reading when measuring an ideal load and the lowest |S11| reading when measuring loads

If you could produce a set of specifications, in a *format* used by Keysight, then people with the right equipment could compare the performance of one NanoVNA-H against and the specifications, and

OK, I see there is a problem that can be solved quite easily. I have 3D printers and Laser cutters, so if you can give me till the New Year, I will work with you all to design and prototype a case

What's needed to connect my NanoVNA- to my Android phone to use the NanoVNA- Webb app? Just a usbc to usbc cable? Martin K0BXB [email protected]> wrote:

So how do you measure inductance using it? Could you tune a trap with it? How? Thanks. Martin K0BXB [email protected]> wrote:

Searching ebay.co.uk has the same issue, no cases just nanovna units themselves. I made my own metal box, so not an issue for me. Maybe the vendors have placed a .com or regional listing condition on
