Welcome to the group! The archives of this group contain much good information including videos and a guide for the VNAs for DUMMIES. Those resources should get you going. Dave -

Hey guys just got a nano VNA. it is a "seesii, nano VNA-H. I need some help in setting it up to see the SWR on some antennas. I have gone through the various manuals and the one that came with it,

1- Would you recommend to clean all 3 elements of the matching network, as I don't know which component will go where ? Can you send me a schematic of the matching network? Possibly I can figure it

Dave, Thanks for the hint. 1- Would you recommend to clean all 3 elements of the matching network, as I don't know which component will go where ? 2- If you look at the trace between the

Yes. The TINYSA is highly useful for frequency domain measurements. As well, the NANOVNA is equally useful for impedance domain measurements. As well, an o'scope is equally useful for time and

The calibrated signal generator output on the TinySA Ultra is a great tool to calibrate or check your S meter and also very useful for determining and/or checking your receivers sensitivity. It also

Hi James , the nanovna H H4 and LiteVNA64 , whith the recent FW has the TDR function but named TRANSFORM . You can reach the relative menu , tapping the DISPLAY >> TRANSFORM >> TRANSFORM ON. In the

They are completely different instruments, used for completely different purposes.The NanoVNA is a vector network analyzer. It can be used to measure resistors, capacitors, inductors, transmission

Hi As a hamradio operator what can i do better with TinySA ultra then NanoVNA H4 ? What kind of measurement with TinySA can be really usefull for antenna, filtering .. around hamradio activity ,

The NanoVNA-F-V2 has a convenient TDR function: It has its own menu choice. Just requires settings dependent on cable speed factor and short/long cable. Quite intuitive. Firmware 0.5.4 handles

Yes. When I commented "clean" the copper from beneath the inductors, I imply no copper beneath the component(s). Yes, that will introduce a slight impedance bump in the line. However, even a bit of

I know the NanoVNA H4 has a TDR function because I've used it. It isn't called that in the menu and is a little tricky to figure out. There is a Youtube'video that describes its setup. Also message

Haven’t bought one yet but I’d like to make sure I get a version capable of the TDR addition. I’ll have to figure out how to add it if necessary after receiving it. Thanks.

Stan and Thomas.. Thank you! The menu is very helpful! Got a whole lot of learning to do, i'll be fun! -- William, k6whp -------------------- "Cheer up, things could get worse. So I cheered up

Dave, That's very interesting. That is what I came across the datasheet of the capacitors I bought. Look at the picture, I think that's what you're talking about. Unfortunately, it is not mentioned

Dave, the first photo is with the 10pf cap and at 150mhz it measures 10pf. Since you mention measuring all components, do you have any tips on getting a 50ohm match on the inductor at the desired

When constructing filters, I ALWAYS measure every component before building the filter! With that, I seldom have to do ANY tweaking with the completed filter. If your first image is without anything

Zack, Here's a link to the filter I'm building. It's not a chebyshev, there was an article in QEX about it comparing the two. https://github.com/F6ITU/k_zolotarev And the qex

Where did you get the filter design you are using? Playing around with my filter design program, I found it appears you are using a 7th order Chebyshev low pass filter, inductor input. Possibly a
