Siglent SSA3000X and SSA3000X-Plus Spectrum Analyzers

[cubitus]

On the official site of siglent.eu
On the SVA1000X in the DMA options there is this screenshot:
https://www.siglent.eu/product/1150761/siglent-sva1000x-dma-digital-modulation-analysis-license-option
I never saw it on my device, do you have access to it?
Thanks

@cubitus

No, this is a screenshot of a very old firmware version. Currently, DMA is more extensive.

Often the USA website is best to dig deeper into the options:

[cubitus]

How is the first hexadecimal line generated to accept the SVA1000x firmware ?

Is it necessary to make this modification with each new firmware ?

thank you

[Bicurico]

The first line changes the FW ID and the resulting checksum.
The required hack to obtain these values is not public and they are specific for that given FW.

[cubitus]

OK so @tv84 knows how to do it...

When there will be a next firmware the 3.2.2.6 for example, will it be necessary a patched version or not?

thanks

Hi,everyone.
Thanks TV84!
I have folled Reply #1622 to crossflash my SSA3021X-PLUS.
After reboot, I using 'telnet <SVA IP address> 10101' to connect to  SSA3021X-PLUS. Unfortenagely, the console printed as follows:
Unable to connect to remote host: Connection refused
Why?

No more time to hand in homework...

To close things off:

"SSA3000X", "SSA3000X_Plus", "SVA1000X", "SSA3000R"

Summarizing the collected information :)

Script to run:
https://www.online-python.com/PX3v0J8nbs

And added to the attachment (as if the links stopped working).

Weird.
On sds3021x (non plus) with factory-enabled tg only EMI and 3032 options worked. AMK and REFL are rejected...
Any idea?

Thank You!
I've figured it out by myself, but I can't use new code at a moment. This confirmed mu guess was correct.

Added:
Yes, it worked!
Wonder why no info about this method in "hack" thread...
At least I did not noticed any,

Hi guys!

I've encountered a problem after crossflashing SSA3021X plus to SVA3032X:
Cannot connect to ftp server.
I've managed temporary activated it through telnet:

Code: [Select]

tcpsvd -vE 0.0.0.0 21 ftpd /Also before this I changed root password to connect via ftp.
But after reboot ftp, of course, is gone.

Also I've noticed that in etc/inetd.conf there is no startup of ftp service, only telnet.
I've tried to edit it with next string:

Code: [Select]

21 stream tcp nowait root ftpd ftpd /But it is located in cramps file system and therefore read-only. 

Also I've tried to upload old firmwares, but SA doesn't allow to do so. Can only upload previous version where ftp server also doesn't work.

Could somebody help me? With manual editing files through telnet or maybe other way?

Update

Adding

Code: [Select]

tcpsvd -vE 0.0.0.0 21 ftpd / -w & to startup_app.sh after telnet line solved problem.
Now able to connect to ftp using root login (by default login: root, password: ding1234, but can be changed through telnet)

Hi. I'm not expert in phyton, so I can't make the aliases work.

This is the explanation, but I really can't get that it work.

Jepp, the mistake he made was the option.
# Options:
# CAT  = AMK
# Meas = Refl
For AMK he must use CAT as an option also for Refl he must use Meas as an Option.

If he take this options everything is fine.

regards Chris

Thanks Jipo

[IAmBack]

Jipo, just edit script code and change:
- AMK to CAT
and
- Refl to Meas
in python script (in the line with all options listed).

[jipo]

Hi. I did it.
But the system messages says that the key is invalid with CAT or AMK.
With Meas, the system inmediatly says that key is invalid and I can't continue.

So, I tought that I was doing wrong. But the script worked fine with BW.

I have SSA 3021X, it came with FW 2.1.1.1
Maybe the problem is that I updated the FW.

Regards

Line from "my" script:

Code: [Select]

otheropt = ('AMK', 'EMI', 'TG', 'Refl', 'DMA', 'AMA', 'WDMA', 'DTF', 'VNA', 'RT40', '3021', '3032', '3050', '3075', 'ALL', 'Meas', 'CAT', '1HZ', '3M')Of course "Meas" and "CAT" was used (with success).
Old unit with fresh FW.

Do you have any official option license inserted?

[jipo]

Do you have any official option license inserted?

Hi. No, except that TG was activated from new.

But, I belive that the scrip works, with a little strange detail.
When I wrote the key, the system said that the key is right. Also appears the notice that the license is permanent. But when I saw the system message, the system says that the key is invalid.
Despite that, the BW got 3.2 GHz. But I was unable to know if others key are valid. I belive that they are valid since first time, even without aliases.

At this moment, all options work. I don't know if it is because the licence's time is running yet, or the permanent key is valid.

I will tell you if anything changes.

Thanks and regards.

All/any license key is only valid to one instrument and all/any option license status is displayed in the Sys Info as Permanent or trial time remaining in minutes.

The status of every license is plain to see.

Thanks for clarification. I didn't know that.

Also thanks to everybody who helped in the "upgrade" of this machine.

I have a SSA3015X+ in my haste to upgrade it to an SVA1015X I tried using the cross flash image from here:

https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3564805/#msg3564805

However I now realize this was designed for use on the SSA3021x. The flash however did install on the instrument and it boots. However the touch screen and buttons do not function. I can connect over the web interface and I can connect a mouse locally to navigate menus.

However, I can not successfully install any of the the other ADS files, or any of the telnet ADSs to enable telnet. The telnet files go to the "Updating" screen and then return to the firmware menu, but the telnet port does not appear to be open.

I've disassembled the unit and can see the serial port output. However the unit does not receive any serial port input (does an link need to be added somewhere to enable serial input?).

I will keep trying to get serial access, but any pointers are most welcome!

[new299]

I fixed the issue with my SSA3015X+ and wrote up my notes here:

https://41j.com/blog/2022/10/siglent-ssa3015x-plus-upgrade-issues/

Essentially with some fiddling I could re-flash the backup mtd partition images via uboot.

[Bicurico]

Every device has a Product ID.

The FW upgrade process matches the Product ID of the device with the Product ID of the FW upgrade file: only if they match will the upgrade proceed.

Some FW upgrades will increase the Product ID number to make it impossible to downgrade the FW.

What you have done with your hack was to change the Product ID from SSA3015X+ to SVA1032. This will of course make it impossible to revert to a SSA3015X+ firmware!

Your way of fixing it was, however, a bit crude, like using a sledgehammer for a tiny nail. You could have just edited the Product ID in the respective file and then flash the right FW.

I am glad that it worked out for you, but messing with uboot has some big risks: if you make an error (typo) or if the flash has an error, you might end up with a brick.

My recommendation is: when you f*ck up, post here and wait 2-3 days. Someone will help you. I know from my own mistakes how desperate it is to have an expensive device with a FW problem, but hasting to fix it can make things worse in no time.

Also, never upgrade, cross-grade or hack a FW, if you are not fully awake and informed on what is going on.

Cheers,
vma

I didn't see this cry for help. The poster didn't give us time. For sure a patched thing could have been crafted to solve the matter.

Nonetheless, and although with greater risk, the lesson seamed to be a good one as there is no better way for learning than doing the study ourselves.

Well done.

[dodonny]

Hello everyone.

Thanks for all the work done on this topic. People who find hack, and people who help others.

I have a SSA 3032X (not plus). With only TG and Refl valide license and official.

Never flashed, version is software is 1.2.8.1 and hardware is 07.03.00

I executed the python script with my Host ID (I had more char to put into than the numbers of "0" on the placeholder), it run great and give me a bunch of results.

I had only 4 options on my device and 2 was already officials. So have only 2 to go.

the ALL serial give me an error, the EMI worked fine but the AMK option always give me an error.

Any clue on what I've done wrong or what can I do to complet the process ?

Thanks in advance.

another one with the "thread not read" error?
