Mirror your NanoVNA or LiteVNA screen
- Plug the analyzer into this computer's USB port and turn it on.
- Click Connect and pick it in the list.
The page picks the fastest method your analyzer supports. Remote desktop streams only the parts of the screen that change and lets you click and drag on the mirror to use the analyzer's touch screen. Screenshot polling copies the whole screen over and over, limited by the analyzer's USB speed (about 500 KB/s).

Older firmware, or Remote desktop unchecked, falls back to screenshot polling (about 3 frames/s at 320×240). Polling pauses the analyzer's sweep briefly for each frame.
Works in desktop Chrome and Edge. Only one program can use the port at a time, so close NanoVNA-Saver or any other program using it first.
