Hack of Sigllent spectrum analyzer ssa3021X?

[trp806mo]

Is it possible to enhance the RBW to 3Mhz on a SSA3021X+ in order to speed up the SWT with the python script for example (I prefer not to try it if it's not possible in order not to break my warranty) ?

Hello

I have Sigllent Spectrum analyzer with model number SSA3021X.
SW1 is 1.3.9.6 can i upgrade V3.2.2.4.0?

can this model upgrade from 2.4Ghz into 3.2Ghz?

Hello

NO !
V3.2.2.4.0 is firmware for 3000X Plus models.

The correct firmware is here:
https://int.siglent.com/download/firmwares/?ProId=29

can this model upgrade from 2.4Ghz into 3.2Ghz?

Oh please, yours is a 2.1 GHz model, not 2.4.

It will upgrade and the methods are in this thread, please study it.

where can i find the firmware 7.07?

thxs for replying, my current SW1 is 1.3.9.6 and HW is 0C.03.00
do i have to upgrade to the latest firmware? SSA3000X Firmware – V1.3.9.8 (Release Date 08.15.21 )
or SSA3000X_Firmware_V2.1.1.3R1 (Release Date 09.16.22 )

I found it is NOT for the faint of the heart.

Initial state: brand new SSA3021X Plus with firmare 3.2.2.5.0

No so. Currently all of this can be done by people with pacemakers or even TAH's  but many continue to not read the latest developments... this thread is only 43 pages long and most of them only repeat what has already been said obscuring important details.

The easiest path is here.

Ah yes I saw that post. However, I like to understand what I do... I was not going to hex edit a bunch of bytes in a firmware image not knowing what it does. The more complicated way is much more transparent.

I think it would be good if you could explain what this modification does. I am assuming you are changing the header of the upgrade file and its checksum, so that the SSA applies the SVA firmware, thinking it is an SSA firmware. But more details would really help!

As you say, a lot of minimalistic, 2-3 lines post, require a lot of context and are really hard to process for people new to this thread. 40+ pages is a lot of information and we should not require people to read everything to do the hack.

By posting what I did, from A to Z instead of requiring people to compile a bunch of partial information, I was hoping to give a one-stop-shop post with clear and transparent explanations. But yeah, it's likely the way you shown is much easier and simpler could just do with more explanations

Thanks for your help, definitely would not have been possible without you and others

That's exactly that and only that!    (it's in the thread somewhere...)

You did well, no worry.

Hello and Happy New Year! to everyone

I've just received my new SSA 3021X plus and I'm very happy but the firmware is 3.2.2.5.1R20 
And Unfortunately the backup SSA3000X+_backup_11411.ADS doesn't work for me
The usb stick is empty only with ads file. Maybe I'm doing something wrong or it is related to the firmware
I also try downgrade to 3.2.2.5.1R1 the screen show progress but  after rebooting the firmware is the same.

Any ideas?

P.S. I'm not familiar with linux but is it anywhere instructions how to make backup trough telnet and of what?
I've already hex modified 3.2.2.5.1R1 ads file.

[DeDe]

Regarding not working backup SSA3000X+_backup_11411.ADS - of course script will only work under following conditions;:

• Before crossflash on original SS3000X *Plus* devices with V3.2.x.y.z firmware
• Plugged in USB-Stick formatted with a single FAT32 partition
• USB-Stick should allow write access: try with File|Create Folder if you can create a new folder on your stick

Otherwise reformat the USB stick with FAT32 (not ExtendedFAT) and with MBR (master boot record).

If it still does not work after that, it will be necessary to go the way over telnet and to re-mount the mass-storage filesystem once in RW-mode.

[el_man]

Thank yo so much!

I've already tried all of this, usb stick is freshly formatted.
The device is in initial state with its firmware 3.2.2.5.1R20

How about telnet access I've succeed trough pot 10101, but and how to change the filesystem to RW-mode?

[DeDe]

I just tested it again, I think using File|Create Folder works because the main application process /usr/bin/siglent/Aladdin runs as root and therefore it can write.

So telnet to your device and execute:
mount -o remount,rw /usr/bin/siglent/usr/mass_storage/U-disk0

Then load this "pseudo" firmware update with backup script.
After you are done just restart the device once, then all filesystems are read only again.

[el_man]

Thank you again so much For the help DeDe!

I succeeded in everything and the upgrade is finished successfully
But unfortunately It seem like something is missing in VNA part maybe This VNA cable.
The Smith chart was total Mess and after adding the two configuration files na_1p na_2p it becomes more or less normal at least now is in the contour of the chart
But the port Doesn't react to any Load 50ohm Close - Nothing!

Where is this "VNA cable" and is there a fix to this?
Any other guy with same version of this firmware 3.2.2.5.1R20 Does Experience the same problem?
My unit is quite New - manufacture date is 13.12.2022 Maybe because of the unlucky date they stop putting the cables
or at lest at This date

Any help will be Highly appreciated!

Sure you connected to the right port? Port for S11 measurements is TG, not RF in.
Measurements will be very inaccurate without a calibration.

Hello and a happy new year to all

I have a problem with my "open" SSA3032x (w/o SN)  FW version 1.3.9.7

Refelection mode measurement is only able on Trace C and cannot changed to other trace No

Not sure whether this problem is caused by "open procedure at all", FW Bug or defect of my device.

Hopefully someone can help

Thanks and regards
Thomas

First sanity check is to Preset to Factory settings. How Preset operates is selected within the System menu.

...no change, problem is still present

[Bicurico]

That seems to be normal behaviour.

On my SSA3021X trace C is used and cannot be modified.

Not sure why this is, but I guess that this way the device does not touch the more commonly used traces A and B.

ok thanks

Also i found a video in the web describing reflection measuring mode.
Was also on trace c

...update to 1.3.9.7 and than make your modifications.  Further FW update not necessary because 1.3.9.8 is only for newer HW

[Zbych_]

Further FW update not necessary because 1.3.9.8 is only for newer HW

No, you can use 1.3.9.8 with old hardware.

[ThomasM...]

No, you can use 1.3.9.8 with old hardware.

...however it is not necesarry to update to 1.3.9.8 because the diffeence to 1.3.9.7 is only the compatibility to new HW parts within the Analyzer
I am wrong? Than please explain more in detail

Anyone looking to sell one already hacked?

Hi,
my new SSA3021X+ (fw: 3.2.2.51R1) is just hacked with TV84 patched SVA firmware (backup done first), same version of SSA, all went OK and the VNA module appeared in system info list as permanently activated as TG, all other are time-limited demos.

The model declared remain as SSA3021X+, I've used the script to change to 3.2GHz (3032)... activation keys are accepted only with SVA1000X model specified in the script, after a factory reset the model is automatically changed in SSA3032X+ in system info, s/n UNchanged as the original (SSAxxx...)

Then I used the 'ALL' key to enable all options, 'DFT' option appeared in the list with all other permanently activated.

My question:
IT's necessary to change the info model to SVA1032X modifying the 'NSP_trends_config_info.xml' file ?

Thanks
