I got tired of trying to keep track of all those little SMA calibration standards and adapters that I keep with my NanoVNA, so I made a thing! It's a small pcb that uses common 1/4" wide edge mount SM

I think the Ojisan firmware is intended for the NanoVNA V2, not the V2 plus4. --John Gord

Hello everyone. I've just bough a NanoVNA V2 plus4 from Amazon and was interested in flashing the Ojisan firmware. After flashing via normal procedure as written in Nanorfe website, the VNA stays with

No, 12k is IF used in measure. So not possible measure on this frequency or it harmonics PS in H4 possible change IF in config-expert settings menu

Where come from the 12 kHz noise? Possible to filter?

Yeah, I do it by a screen cap of the window (attached, MacOS-X). The calibration files do have the frequency range: # Calibration data for NanoVNA-Saver ! SOL Calibration ! 27-30Mhz 101 Points # Hz Sh

And of course, the software should remember where it was when it was stopped, so that it would start from there next time.

After some use I noticed a couple things which could be better in NanoVNASaver.win.x64 software. First, I posted this also to https://groups.io/g/NanoVNAV2 but after a couple of days it has not appear

There are NanoVna V2s for higher frequencies.

Hi, Should add that the nanoVNA, is not the best tool for amplifier testing. The output is square wave, so there is quite a bit of power in the harmonics. And worse for amplified testing, on once you

No advice to give on your RF ID detector, but I have spent most of my career testing high-power amplifiers with VNAs, so I can offer a few basic rules: 1. ALWAYS assume the amplifier may put out its m

Understood Don. Godwin should insure that the amplifier in use is stated on the data sheet... unconditional stabilty is met. Perhaps you can suggest cautionary steps that should be taken prior to conn

Hello Godwin. Along the same lines as Herb's post. You can try the following. Make sure the amplifier in use is specified to be unconditionally stable. Otherwise you run the risk of damage to the vna.
