Hello, this is my first post.
I read everything (probably with understanding) and decided to act..
I have brand new SSA3021X Plus with firmare 3.2.2.5.0.
I followed the post #1619
1. Initial backup of SSA3021X Plus with SSA3000X+_backup_11411.ADS - OK.
2. Telnet access for SSA3021X Plus - OK
Backup main directories - not OK.
I wanted to understand your words properly, so I used chroma's built-in translator,
but the translator in the command lines was creating errors
from aryginal line:
"cp -R /usr/bin/siglent/usr/backup /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup"
after translation, I got an extra space in the destination directory:
"cp -R /usr/bin/siglent/usr/backup /usr/bin/siglent /usr/mass_storage/U-disk0/SA-backup".
Of course, I didn't notice it. With the help of ^c and ^v I sent these commands to SSA.
I received many error messages.
Most messages were of the type: "cp: can't create symlink ...",
and some: "cp: recursion detected, omitting directory..."
I don't have the entire log from putty .
I checked bakckup and on the device that the following directories are empty:
/usr/bin/siglent/usr/backup and
/usr/bin/siglent/usr/usr.
I updated the firmware to 3.2.2.5.1R1
I restored the factory settings
This did not change anything.
I think I broke something.
Device seems to work well, what should I do next?
If some files are missing how to restore them?
In the end, of course, I want an SVA.
best regards

I just saw a video where an ssa3000 is shown working on a computer screen and the truth is that it has been quite depressing. Does easy spectrum always work like this or is this the exception that proves the rule?
The image is at the moment 44.15

But the directory /usr/mass_storage/U-disk0/SA-backup does not exist, so the cp command should have shown an error "cp: usr/mass_storage/U-disk0/SA-backup is not a directory" immediately...

Thanks for the support. I will order a chip from Aliexpress. In my country I did not find. I have no intention of writing to Siglent to have them sent to me. I probably won't answer. Hot air is like a mother tongue to me. I have dozens of refurbished video cards and thousands of phones in my life. I could make a video but there is already one on YouTube. My SA is SSA3021XP
There are other threads here on RF input damage/repair including one from the Asian chap that did the video near the end of the thread linked above. If I get some time I'll try to find it again and link it here.
Looks similar on my instrument - maybe the dip between 0-5kHz is a little bit lower..
Hello
After successfully repairing the RF input, I want to compare the TG at low frequencies. Can someone take a screenshot of mine?
I think in the area around 9khz it should straighten the line to -20dbm.
I checked the RF input with an external tracking generator and the line becomes horizontal after 9khz. And with the built-in generator, this is what is obtained in the picture.
I didn't follow the whole discussion, but you should know that the instrument specifications start at 9 kHz. So it's normal that the line is not horizontal.
IMHO this is splendid performance for a SA in this price category
Today I repaired my SSA3021XP for the second time. The repair was much easier than the first time because I already had experience and I used low temperature solder.

Wow...
You have a talent... Damage the input of the spectrum analyzer twice is already a high level of talent
only because Mouser is offering volume discounts on parts you don't need to replace the frontend every day ! 😉
Have mercy with the PCB.
BW RBW not working
SSA3021X+/hacked SVA
FW 3.2.2.5.1R1
all options enabled
as per TV84 instructions
when BW pressed during NVA mode, the option is greyed out , only default IFBW 10KHz
it works in SSA mode
Anybody has the same problem ?
did I do something wrong ?
