Hi Larry, that's curious. Have you tried turning it off and on again, as they say? :-) On the face of it, that looks exactly like what would happen if the device was connected, and thus found, when

YES! Thank you for the Rescan function, Rune. However - it's throwing errors looking for COM12: 2019-09-27 07:45:32,042 - NanoVNASaver - INFO - Startup... Settings:

Thank you for the massive effort you have put into this software! I have had zero problems running previous versions with Windows 10, but this latest version AVG seems to think there could be a

qrp.ddc, Thanks for confirmation( #1831 ) and additional advise.

Bug was confirmed and fixed in edy555 (ttrftech) commit 0b885f2. Beware older versions have a bug in S21 calibration. Carlos

Hi all, did someone of the group measure the initial charging current of the battery when almost empty? My NanoVNA draws 900mA while connected to a 5VDC power supply! The current drops down to 850mA

If you carefully remove the for plastic screws you will have access to the screen cover. Simply peel it off and reassemble

Or use a Standard 5v USB Power Pack! Enough choices Up to 25Ah

I am in complete agreement. That was the point of my post. Unless the velocity factor is a lot more consistent than I would expect, that's all you'll be able to do with *any* TDR. And for practical RF

It's a tricksy little thing...the screen protector film is frequently UNDER the front bezel. You need to take the front bezel OFF before you can easily peel the film off using the handy green tab. 73,

So you removed the plastic film that is on the screen? Mike WY6K "... somewhere in the distance, there's a tower and a light, broadcastin' the resistance, through the rain and through the night..."

My screen tab is on the protective screen.

I don't understand all the theoretical limitations associated with different FFT sizes; but from a practical use point of view if my $50 device, as a additional throw-in, can measure a 65 meter length

The 900 MHz upper limit implies a sinc(t) width of 2.2 ns. A 256 point complex to 512 point real FFT will provide a long enough trace to reach the end of a ~50 m cable. The screen pixel count is not

Erik Congrats with your Call 73's Erik ON8DC

Rather than larger, I was hoping for wireless (Bluetooth), perhaps by ESP32, using a smartphone or tablet for display and complex calculations without USB and ground loop concerns.

Hello, Allow us, please, to inform you that, after: [15] : /g/nanovna-users/message/3147 we just uploaded our well-formed mathematical expressions of full-one port vna measurements

I'm talking about OUTPUT impedance of CH0 (don't confuse with INPUT impedance). I didn't hear that it is possible to measure output impendance with another VNA :) You're needs to measure amplitude on
