I looked at the case, I had similar thoughts, but I would have holes for the coax cables to connect to the NanoVna and also an extention to mount whatever test board you are using, in my case the

That is cool. 1. Do you have pics to share to show? 2. Are you going to make any to sell, for those of us without 3D printers? (Yes, there are still some of us out there)... [image: photo] *Bob

What’s the thingiverse number? Thanks, -rick, K7LOG

I just don’t have exact measurements to verify the fitting for the other models. Sent from my over-rated IPhone 7 Plus. Any Mis-spellings or grammar errors are due to my IPhone auto correct feature.

On my own PC and with my nanovna firmware 0.8.0 or dislord's current one and with my nanovna v2 0.3.6-rc2 works more reliable as v0.3.4 and a lot better then v0.3.0 but some quirks seems to exist, but

Git Hub shows 0.0.3.6-rc2 is the latest version of NanoVNA Saver Should I be staying with the 0.0.3 version? or moving to the 0.3.3.6 version? KEoZUW John

I'll note that unwanted shunt-capacitance can result in errors (that increase in frequency) when measuring large impedances using "configuration 3" in the Copper Mountain doc. This same shunt

Thanks Darrell I'll take a look. I've been putting off designing one for myself so this may save me some time...

FYI - In the current source code the internal on-chip vbat divider is always enabled. There is an option where the divider is switched on/off before/after the actual vbat measurement via ADC1_17

This measurement technique was addressed many months ago in a prior thread. https://coppermountaintech.com/measurement-of-electronic-component-impedance-using-a-vector-network-analyzer/ You can now go

The Vbat, at least what I see in the sources for H4, is being sampled such the Vbat voltage divided by 2 (internal on-chip divider, most probably disconnected when not in use) is converted via the ADC

Just FYI, I designed a protective case for the H4. It is a bit oversized to allow additional SMA connectors to be left on to prevent abuse to the connectors attached directly to the circuit board. The

Dear Clifford, I've studied Dunsmore's publication (thanks for the link!), as I can understand it is more about the way to enhance the U7's input (I'm referring to the 3.4.2) network, namely, the

There have been several threads in the various nanovna forums about the value of applying engineering to these devices. For the record: You statements are incorrect, except, perhaps where you imply

Nice write-up of the measurement problems. Rings a few bells. Now with the nano, I measered several resistive loads (47 to 10k) using S11 en S21 in the HF range a few weeks ago. For high impedance

Excellent! Thanks very much, Pete. 73, Jeff, k6jca

Hi Jeff, Here's the paper: Showed up below as Challengesandsolutionsforimpedance When I did the complex algebra it was a good refresher. 73, Pete

It was a bug releases between v0.3.0 and v0.3.2 fixed in v0.3.3 https://github.com/NanoVNA-Saver/nanovna-saver/issues/202 73 Holger, DG5DBH
