What do you mean with native serial? RS232? Doesn't the UART in-out pins work at 3.3V levels?

Ok , so I put GND ,RX, TX DIRECTRLY TO RS232 INTO A computer , I was wrong ?
Not all computers work, my own main machine garbled it completely actually so that does happen
1. Check your pinouts and post pics of your pinouts to both sides labeled
2. Check 115200 8N1 is set
3. Sanity check your terminal uart does indeed actually work
4. Use a different computer if uart works but still cant read the device
If you have a scope that can decode uart, attach it to the lines, you can confirm that it is indeed actually putting out correct data
Doing all of this should lead you to finding the issue

I manage to make him alive ! the problem was the interface : so I put a ttl to translate from SSA to computer.And now I will start again with the update. Thank you all my friends. you are so smart, thank you.
Good news iulisan, glad you've got your SSA3021X Plus working again and upgraded too
I'm not especially gifted in all this, but have successfully upgraded my SDS2120X Plus (this went well) and more recently the SDG2042X (some difficultly since I am using a MAC) with the help of folks here. Now considering the SSA3021X Plus, which seems at another level of difficulty.
Is it possible to upgrade the SSA3021X Plus without having to go thru all the issues you've encountered, especially having to get inside the instrument and use the UART?
Best,
I took the plunge and tried the cross to the SVA1032 from a new SSA3021X Plus following the details from #963. Long story short is the Model Number changed to SSA3021X Plus, but only SA and MA are highlighted under Mode, VNA and DTF are not highlighted. Under SA use the top frequency range is still 2.1GHz. Still only the TG is Permanent.
System Info
SW1 2.2.1.2.5
SW2 20191022-5
SW3 000000D4
HW 00.00.00
The SSA has SW version 2.2.1.2.3r1 initially and after a failed attempt at the cross I updated the SSA FM to 2.2.1.2.5
Any suggestions on what to try and help is appreciated.

Follow this updated process that someone compiled from our various back and forth

The SSA has SW version 2.2.1.2.3r1 initially
As your SA was originally delivered withQuoteThe SSA has SW version 2.2.1.2.3r1 initially
Once you have it up and running your HW may be missing the connection between the tracking generator and the input. So if your VNA results shows abnormal graphs and it cannot be calibrated you will have to open up your box and insert a short SMA jumper(approx 5 cm/2 inch needed with 90o connectors

Good news, looks like the SSA3021X Plus has been transformed into the SVA1032X
It appears the SMA cable is installed also

Thanks to to Elasia, tv84 and Emo for all the help

Best as I can see mawyatt's settings and after a Preset to clear mine here's what a real SVA1032X looks like in the same Smith chart mode. FW = latest dot 8 version.
Maybe rig up a 50 ohm resistor on a cable and LF sweep it in Smith R+jX mode and see if it returns a result near the center of the display.
