Как пользоваться AnyDesk для удаленной работы?
AnyDesk – бесплатное средство для управления удалёнными ПК, ближайший конкурент TeamViewer и Ammy Admin. Создано по принципу: скачал, запустил, подключился и работай. У приложения миниатюрный однооконный интерфейс без запутанных меню. Соединение устанавливается в пару кликов. Доведённый до совершенства код работает практически без ошибок.
В статье покажем, как пользоваться AnyDesk: настроить, установить соединение между ПК и устройством на Андроид. Разберёмся с основными функциями программы, вопросами, возникающими в процессе эксплуатации приложения.
Changing your display.
For my next blog post, I want to measure one of my Ultra-Wideband Spiral Antennas. For this, I am only interested in S11 measurements for the time being, but it would be nice to show SWR also.
Click ‘Display Setup …’
I will choose VSWR for the lower left plot.
HexAndFlex 300MHZ+ Circularly Polarised Spiral Antenna.
Now lets have a quick look at how this compares to a professional grade VNA. I initially tried using the NanoVNA saver to import a Touchstone S2P file from a proffesional grade VNA, but i didn’t trust the results, so I used QUCSstudio to import them both.
Using QUCS studio to compare touchstone files
Top Tip – QUCS studio can read your touchstone files and make them part of an electronic simulation. It can also automatically calculate a matching network for any given frequency.
This was a quick test and I really didn’t take too much care to isolate the cable from the antenna. At lower frequencies(below the 300MHz design frequency) the cable is not as well isolated from the antenna. To make better measurements of this I would want to add a balun, or some ferrites to the cable to help isolate the DUT(Device Under Test) from the cable.
Что делать, если не получается в AnyDesk отключить запрос на подключение?
Закройте AnyDesk, если программа запущена, затем нажмите на иконке ЭниДеск правой кнопкой мыши, в открывшемся контекстном меню нажмите на “Запустить от имени администратора”.
Далее выполните все действия, описанные выше. Проследите, что пароль вводится латинскими буквами.
Раз AnyDesk запущен от имени администратора, то в меню “Безопасность” не будет пункта “Разблокировать настройки безопасности”. После чего должно активироваться в AnyDesk автоматическое подключение.

I want to communicate with my nanovna directly with an ascii terminal on my MacBook but I don’t understand how to accomplish that. I tried installing an ascii terminal on the Mac but I can’t seem to get anything to connect. I assume that the nanovna needs to be running but I don’t know exactly what serial port to use and how to make the nanovna establish a connection.
Thanks
John N4OEEverything works fine on my linux box but when I tried to install nanovna-saver on my Mac I get this runtime message. Anyone have any ideas? I want to use my nanovna to collect data at the feed point of an antenna and my linux bos it too big to move out to the antenna.
Thanks
John N4OEIs there a document describing the NanoVNA-Saver SOFTWARE concept ?
I did not find much about HOW it interfaces with NanoVNA in github.
Flow chart / block diagram would be nice.
In pseudo codesetup serial – word length, baud rate etc…
send data via USB (serial?)
verify NanoVNA “signature”I had installed all of them before I tried to run nano….
Paul, I had problem on win7 64bit because the virtual usb driver was unsigned and windows would not allow it to run. The driver in question can be located: “C:WindowsSystem32driversusbser.sys”
I downloaded the utility “dseo13b.exe” free on the internet to create a signature for the usberser.sys driver: try: https://www.filecroco.com/download-driver-signature-enforcement-overrider/

Peter, Thanks for your response. When I try to run nanovna-saver-v0.2.2-1.exe in cmd window I am getting the following message:
C:UserAdmin>nanovna-saver-v0.2.2-1.exe

[376] Failed to execute script nanova-saver
=================================
Have you had the same error message or something else?- April 5, 2020 — 11:01 am Peter Kirk
Paul, probably the driver signature issue causing the python script to fail.
1) Connect your nanoVNA to the usb port and make sure the nanoVNA is turned on.
2) Windows should generate a sound if it detects the presence of your device (you may see a driver msg in lower right of screen)
3) Open your system device manager and check for a driver error in the PORTS (COM & LPT)
or under VIRTUAL COM PORTS
4) If you see the following driver error: STMicroelectronics Virtual COM PORT, then you probably need to sign the usbser.sys driver as per my previous post. (make a back up a copy of the original usbser.sys for piece of mind)
cheers- April 5, 2020 — 11:26 am Paul
Device manager shows the PORTS (COM & LPT) and STMicroelectronics Virtual COM PORT with No error message (“This device is working properly”).
The error message I quoted in my previous message appears regardless I have Nano-VNA connected or not to PC…
I asked a friend of mine who does not have Nano-VNA meter but has win 7 (64bit) installed on his PC to downloaded and run nanovna-saver-v0.2.2-1.exe. And he was successful. So maybe there is something wrong with Win 7 config on my PC?- April 5, 2020 — 9:39 pm Peter Kirk
For Windows 7, it does require Service Pack 1 and Microsoft VC++ Redistributable you should download both 32 and 64 versions.

I have problem with running nanoVNASaver on win7 (64 bit) – cannot start. Where can I get any support?
I don’t suppose this software is available for Mac OS?
- October 5, 2019 — 9:46 pm Timmy
Click on the github link and READ, and follow the instructions for “Mac OS: Homebrew” ?

Ok, thanks very much.

50 Ohm measuring
I am aware that the Ohm values are not precise to the 4th digit, but the differences should be OK. Unfortunately the difference CH0 input to the 50 Ohm load is in the opposite direction from 50 Ohm, it is about 3% mismatch. That is compensated by the calibration.
From company SDR-Kits you can buy a very useful Testboard. Fortunately the documentation can be downloaded from the web page, so you are able to make a home made version. See the picture below.
.
With the very useful Python software nanoVNA-saver you can calibrate more detailed, e.g. with 505 points instead of the standard 101 points. See below a diagram of the 50.0 Ohm Load in the Testboard, calibrated with 505 points.See the diagram below. The S11 Return Loss was improved at 900 MHz by about 10 dB.
For an easier finding of the Calibration Setting fields have a look at the Calibration window on the right.
For a better remembering of the Calibration File Name I put it in the Notes field.
In order to enter Calibration standards settings, you have to remove the mark in the field Use ideal values.
In the field Saved settings it is good practice to set a name, in my case Testboard.
With a click on the button Save the settings are stored for the next use.
At the next use select at Saved settings in the name field the name of your settings. Then click on Load.
In nanoVNA-saver version 0.1.3 it happened to me, that after clicking on button Load, no settings appeared in the fields. Clicking on the two fields made them visible.
