So I have spent quite some time trying to get the SAA-2N to connect to my PC using a number of different help files. None of which worked. There are a number of missalignments to what the help files say to do and what is actually appearing.

For starters, the drivers were installed without any errors. This was confirmed by the Device Manager display not indicating a yellow triangle. When the VNA is connected to the USB port, it shows up as being on Com 8, specifically USB Serial Device (COM8).

Second, the help file says to enter DFU mode by the following path (per flow chart) "Config" > "DFU". That path does not exist in my unit. My best guess is to enter "Config" > "Bootload" but I can not verify this as it is not in the help file. Can someone confirm this?

Next, when in the bootload screen, the DfuSe v3.0.6 still does not see the VNA. Also I will point out that there is no listing in the Device Manager saying STM Device in DFU Mode, yet the drivers installed correctly. When I try to reinstall the drivers, Windows says the best drivers are already installed.

Next, when looking at the Version screen, there is no Version listed. It just says Version:
Underneath Version is shows a Build Time of June 9 2021 -17:36:19

So is there a help file that I am missing? I appreciate if anyone can clarify this procedure.

Thanks!

The SAA uses a binary programming protocol, not dfu, so I don't know what help files you are referring to.Please refer to docs that reference the SAA series of devices specifically and refer to the SAA user groups for info on programming the device.?
Search the forum messages for SAA and binary?
This topic has been covered a few times here.?

Larry,

I was able to connect on Win 10 using NanoVNA-QT and the appropriate drive
by Cypress.
