Hi Elia, The output of the NanoVNA is a square wave consisting of a fundamental below 300MHz and its harmonics above.You would need to take all that into account in addition to the discrete freq steps

Actually, it DOES power the RTC in addition to being monitored.? What would Vbat-Vss give you? ...? since Vss is Gnd and at 0V and Vbat-Vss is 4V max as specified, you need the diode (or two) or

Hi All, I have a question that I hope someone here can shed some light on. I do not have a spectrum analyser and was wondering if the nanoVNA can somehow be used to perform IP3 and IMD measurements of

I know what it says elsewhere in the datasheet for maximums, but I think it's not that simple for Vbat. Snippet from datasheet - 3.10.3 VBAT battery voltage monitoring This embedded hardware feature

Vaclav, Keep in mind that the ONLY stupid question is the one you DIDN'T ask. Some folks haven't learned that yet. Bruce Nebergall, K4TQL

It may actually be more beneficial to run dual OSes on that machine: XP and Linux In fact, why not run Linux as the base OS and XP in a VM or even drop XP in favour of WINE? Who knows - WINE may run

Hello Tony, The application is written in Python 3.7, and using PyQt5 5.11 as the UI library. Python is not available from version 3.5 on XP, and PyQt5 support ended at 5.5, as far as I can tell. The

I was not going to continue, but...seeing this...In the conduct of running my engineering company, I have spoken with several Li-ion charging system vendors, and especially those who supply batteries

The ADALM-Pluto is another alternative, and has the bonus of being a full-duplex receiver too. It used to sell for ?99, but is still reasonable at ?120 (

Folks, it's called _ NanoVNA _ in the Google Play store. Please do a search.? Android 5 is too old - I believe you need 7 and up for this.? As for the webapp name - there are two: NanoVNA-WebUSB and

Webapp not in play store. Android 5 support impossible?

I am really delighted with NanoVNA-saver on my Windows 10 PC.s It really is a delight to use. I have a small work bench area and I would like to also use an old Samsung Q1 ultra - an early XP small

Just FYI in case you have an older phone. And it's called WebApp, but it's really Android, so perhaps that is where some confusion comes in . 73 -- On the banks of the Piscataqua Rich NE1EE

STM32F072xB data sheet Table 21 Absolute Maximum Ratings Vbat - Vss = 4.0 V Max But it is so close to the wire I think I will change to a Silicon diode!

OK, while 'port' remains a mystery, 'scan' works as expected with edy555 0.3.1-20191021 (unlike QRP 0.4.2): $ ch version 0.3.1 $ ch scan usage: sweep {start(Hz)} {stop(Hz)} [points] $ ch frequencies |

It's Halloweeeeeeeeeen!? Buhahaha

Welcome back. Perhaps you were discussing the signature tome you choose to have appended to your contributions.

Some years ago I bought the USB-SA44B — 4.4 GHz Spectrum Analyzer from signal hound I have been very happy with it (males a great 1Hx to 4.4 Ghz sdr using HDSR with est....sa.dll. I would love a
