If you need good 50ohm match use a 10dB attenuator between DUT and CH1 input Calibrate thru using the attenuator and you loose a bit of dynamic range but get very good 50ohm match. -- NanoVNA Wiki:

I have a latw 2014 Macbook Pro running Catalina. Here is my command to start up nanovnasaver natively. nanovnasaver='python3 ~/nanovna-saver-0.2.0/nanovna-saver.py&’ As you can see the

Just found this: https://github.com/hugen79/NanoVNA-H/issues/20 It looks like an acknowledged design error!

I've successfully used NanoVNA Saver with my MacBook Pro using VMware Fusion and Windows 10. I've not tried anything that runs on Mac OSX directly. The MFJ 259A does some of the same basic

Thanks for your suggestions. I purchased two of these (one for a student), and both of them have the same response. Is this particular to the NanoVNA-H? Does anyone else experience this? I fear this

I am thinking about getting a nanovna, is the Mac operating system usable with them. I am expecting to use it in place of my MFJ 259A. Will it be everything I wish it would be? If I get a heads up

The differential input resistance of the SA612 is about 3kOhm. -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK

Yes - please read up on it in the forum Wiki area - there is a pile of info there you should review before posting the same question 3X in the forum messages. Look at the bottom of any forum email you

Yes it does. I have the latest updates from MS. Gary AA5I

Does this software run on Windows 10 or do you have to download more software? Loren Moline WA7SKT Benson, AZ DM41ux

Actually, it looks that this can be done and the CH1 50 Ohm to be measured just fine. Specifically fot the H4 the schematic shows that this can be done (nanoVNA switched off of course) ->

Don't do this The input of the CH1 mixer is DC decoupled so an ohm meter will measure a wrong value. -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files:

I did not test the S-A-A (V2) sub-850 MHz vs NanoVNA (bad clone), but at 850-950 MHz, the S-A-A is way beter. Also way better than Tom Bayer's VNWA. Attached two measurements from the same antenna.

Thank you for your input. I will weigh my project time and the performance of above units and see how far out I can get before purchasing anything. I really don't even mind buying both, but lately it

Received from Tindie. Dynamic range looks good.

Re: "Why would a VNA for 2-port measurements not design the second port for 50 ohms?" They ARE designed for a 50 ohm termination, how well they achieve it may be another question. I have an H4. When I
