Thanks, I've updated mine and it works great as well! M

Thanks to all!

Sorry, should be Michael, not Mario.

Mario, - calibration does just thet - it calibrates out (ideally, of course) all the variables and takes into account delayes, parasitic LC, etc so that at the reference plane, you have an 'ideal'

Larry, If you do calibration with the adapter installed and the reference plane is at the adapter would you still have to adjust for the electrical delay? Mike N2MS

or you calibrate with standards that attach to the adapter, so the adapter is "inside" the calibration plane.

If the delay of the adapter is significant, then yes. For most of my 900 MHz work it is. For 1 MHz, it isn't. Op 14-9-2021 om 13:58 schreef Chris Pohlad-Thomas:

You can do that (I have) but the best way is to calibrate the unit with the adapters installed to move the reference plane to account for them.

I assume when everyone is using adapters they adjust the electrical delay to account for these?

I took a closer look and there are more of these interferences. They are very narrowband. If the measuring point falls farther than the filter band, they are not there. It has nothing to do with the

Hello Phil! Have You read a File Section? /g/nanovna-users/files/Absolute%20Beginner%20Guide%20to%20The%20NanoVNA Your device NanoVNA H4 (not H3) and Firmware Version 1.0.45 from

Confirming that "-H" variant works on the "Classic" NanoVNA. Just updated it after reading this thread. Compared with crystal measurements done on SAA-v2 with OjisanKobou FW. There is a little bit of

Colours can only be set through the console when connected to a PC, and the saved.? Please read up on searching the forum - it's the first link at the top of the wiki.? A search of console and color

I have just got an H3 Nano VNA its running ver 1.0.45 (Jan 2021 by @Edy555) of the firmware and when I received I was sure the Traces were all separate Colors (But I may have been mistaken) now

DELAY has to be understood here as "Group Delay". It highlights the transit time of a signal through a DUT (Device Under Test) versus frequency. It is usually currently related to transmission

Mario, The 'classic' includes all NanoVNA models from the very 1st model (and clone) up to and including the H (but not the H4). I'm running the latest 1.0.69 on my classic with no issues.

Which variant (if any) works with the Classic (Pre-H) VNA. This never seems completely clear from the descriptions - I think because there's no consistent way to describe the original unit. thanks, M

I have gotten some great input about this, but it remains a problem that such outputs as “real” and “imaginary” come with no documentation as to what they are. I have written a 1 pager that
