Roger, you are indeed correct. I also appreciated Arie's comment. Gregg is also correct for the reflected signal measurement - and in saying that this is related to the V/I/phase in the DUT; indeed

Hello, I recently have problems to display Marker 1, Marker 2, Marker 3 and so on . The graphs are shown but I miss the Marker 1, Marker 2, Marker 3 . values (see yellow colour) Anybody out there who

This is a friendly group and I do not wish to get into some kind of argument with others. If I have posted something in this group which is wrong or confusing please quote what I said and tell me why

Arie, Thank you for your comment. That is exactly the misunderstanding I was referring to in my previous post. I am also on Facebook and I have seen several posts there that stated that the "S11 phase

Hi Manfred, You note that you cannot use NanoVNA Saver under Windows XP. I inherited a laptop running Windows XP from my daughter. I just tried that if I copy the NanoVNA-App to the C: / root

I don't need to "prove" you wrong. Without phase, reactance just becomes a non-dissipative circuit element that doesn't do much outside of resistive losses. One can't have a reactive component without

If you explore NanoVNA-App you will find lots of things. Right click on the graph window to find numerous options. Clicking on the text in the upper left corner of the graph window will allow you to

Roger, I didn't know about that software. I just downloaded it, but it doesn't seem to work with standard firmware, and I'm hesitant about changing to a different firmware, given that the stock one

Maybe the misunderstanding is in the fact that the reflectioncoefficient has another phaseangle than the phaseangle between current and voltage on the load. These are two different things. The

Gregg- I concur with your understanding 100%. Reflection phase with an open is zero degrees and is 180 degrees with a short. Reactive loads (inductive or capacitive) will have phase angles somewhere

Where Roger and I have differed in the past is with regards to the concept of the S11 phase as measured by the nanoVNA. While Roger has firmly stated in previous conversations that there is no

Forgot to my Signature -- Cheers, Ian Melbourne, Australia

Hi Roger et al, I am not about to admit to how many of those misconceptions I have fallen for .... publicly .... :) I have been 'safe' in the analogue, low frequency, ideal component electronic world

The use of a small piece of Teflon or other plastic between the contacts of the clothespin for doing the OPEN calibration may be a bit problematic. It will increase the capacitance between the

Was just over reading Roger’s excellent thread on using a VNA to examine discrete components. I figured I should be clear with everyone that the method I presented below is not and was never

The NanoVNA app by One Of Eleven has this feature built in. It records .s2p files that contain the S11 data that you need. You go into continuous scan mode and then click the record button. It writes

Manfred, Thank you for your detailed and informative post. Lots of good information and tips on how to measure components. I have not seen the same problem with cables up to 30 cm but I will keep what

There is some python code in the NanoVNA repo that gives examples of how to access the NanoVNA, send commands, and retrieve data. It's somewhat simpler than NanoVNA_Saver, which is also Python.

Roger, I think you basically said it all with this list of pitfalls: I can only add a little about my own experiences measuring components: When trying to measure through20cm long SMA cables and

Adnan, Do a search on the message forum for OCTAVE (similar to MATLAB) There is a lot of info on using it with the instrumentation library - that may be useful to you. ...Larry
