Siglent SSA3000X and SSA3000X-Plus Spectrum Analyzers

No, I didn't keep my serial number.
I have xxxxxxxxxxx.
I would like to find out how to do that, if possible.
I will try to update

Happened to me as well.

The fix for me was to power cycle my unit, and then try again. After second try it did the update, and all is working.

I tried 4 or 5 times... it doesn't work...
I will try again tomorrow with clear ideas.

After 6 months, finally decided to try SVA1000X_V3.2.2.5.0.ADS on an updated SSA3021X+ that System Info said was SVA1032X, 3.2.2.4.0.r2
Everything went fine, cal files still work, 10,001 points on VNA, etc.  Only curious thing I haven't seen posted is the sw1 reports as: 3.2.2.5.0.r8 , don't remember others having the r8?

The update took < 2 minutes and rebooted 2 or 3 times.  Seemed to work correctly without another manual restart but I did one anyway after a little tinkering.

Perhaps the thumb drive used makes a difference on success.  I used an old 256M fat16 drive.  The drive had 75 other files and folders so it doesn't need to be empty.

Yes 5 r8 is the latest version although there is no mention of r8 in any of the documentation, only the V5.

Correct the USD drive does not need to be empty for FW updates and the ADS update file can be anywhere on the drive as long as you can navigate to and select it. I have one USB stick with ~20 FW files for many instruments all in a single folder for updating instruments before dispatch and we we update this folder each time new FW is released.
FAT32 is the normal USB drive configuration for Siglent equipment.

Recovery files and their auto loading process is a different matter as they must be in the root folder of the drive for the OS to find at boot to install them however it's wise to remove them once used otherwise if the USD drive is installed in the instrument they will run at every boot. Simple stuff really and no problem if we RTFM.

Wouldn't the SSA3000X-R firmware be a closer fit to upgrade to?
It also has VNA.  (although I assume too slow for any real time tasks)

One must be very careful as there are 3 HW versions in the SSA X Plus and SVA ranges, >1.5, >3.2 and 3.2 > 7.5 GHz

Yes X-R does have VNA, exactly the same as SVA1000X models and the RTSA can be tuned for a bunch of different analysis.

Some screenshots below from a SSA3075X-R we had sniffing the 2.4 GHz WiFi at a recent tech exhibition and while experimenting with eye candy to pull punters into our display buddy hendorog came up with this rising amplitude and frequency sweep snapped in this post:

The SSA+ and SVA models lack the hardware for real time analysis. If you would crossflash, the extra functions would not work and you would risk that the remaining functions would not work either.

Not sure if this one deserves a new post so I'll just post here and see what happens: I feel rather dumb but somehow in the process of playing with the newly acquired SSA3021X Plus, I managed to introduce a 15dB amplitude offset which I cannot seem to get rid of. I feed a 0dBm signal from a trusty old 8656B siggen (whose amplitude I can verify on another HP SA) and I constantly get 15dB of attenuation on the Siglent SA reading. Not sure whether I encountered a bug or not. I know for a fact that it used to work correctly and all I did was to play with demodulation analyzer.

Can anyone lend a hand, please?

Thank you!

Hit Preset and set it all up again but this time hit Save then Enter with a USB stick fitted and post the image here but be sure to have the Amplitude menu showing.

Hi Tautech and thank you for your reply. Here's the screenshot taken from vnc: https://imgur.com/a/qewpEmU

Hmmm, okay before I get my SVA1032X out can you instead use your SSA TG with a 0dB output to see where levels actually are ?
~15dB down don't seem right. 

[benishor]

it don't seem right indeed. Here's the TG view using the same cable: https://imgur.com/a/sCTmziZ

Maybe somehow you have damaged the RF input.
I'd advise you to study this thread and especially the video on P2:

Thank you, @tautech,

It seems likely that I have blown one of the RF input switches acoording to the video in the thread you linked. Is there by any chance a way to get a hold of the hw schematics? I would need to know what chips to change.

Thank you!

No chance unless you can find someone that's reverse engineered it.
HMC1118 is mentioned in the thread and if you have limited experience with SMD get some hot air practice in on scrap PCB's before diving into a SSA PCB repair.

Going way back in this thread rf-loop has mentioned his repairs to SSA RF inputs and maybe he will chime in with some wise advise. 

[benishor]

Kudos tautech,

I ordered some swiches from mouser and I will further pursue the issue once they arrive. I do have SMD hot air experience and kapton tape so that shouldn't be too much of a problem. Hopefully the switch will prove to be the broken link. I get comfort in having the same 15dB difference mentioned in the video you linked.

Thanks again, will be back with the aftermath!

I found a nice easter egg while looking at the firmware. If you open the Mode menu and type 7445368 on the numeric keypad, you can play a version of Tic-Tac-Toe with the analyzer.

I tested it with SVA1000X firmware V3.2.2.5.0.

  Nicely done! 

[oz2cpu]

one more member of the DEAD front end club..
here is mine, latest version of SSA3021X
have now no more protection diodes mounted, see the empty footprints

OMG now we go cry..

most people say -10 to -20db when the first IC is dead
but mine is like TOTALLY deaf !! 
see here new picture addedd TG is at 0dbm, full span curve

[Echo88]

Trying to follow the process described in https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3563577/#msg3563577 to upgrade my SSA3021X+ while using Windows 10.
Im stuck at Point II 5): "enter the following line exactly close to the end, just before line "/usr/bin/siglent/Aladdin &"
   /sbin/telnetd -l /bin/sh -p 10101 &"
I can open "startup_app.sh" and add the line "/sbin/telnetd -l /bin/sh -p 10101 &", but i cant understand how to save this change in the file and get back out of it to enter "sync && reboot".

Can anyone help please?

[antenna]

works on 3.2.2.4 too.  Thanks for sharing that!

7445368 spells siglent on the keypad!

[benishor]

Sorry to hear that oz2cpu, I feel your pain. Any idea on how it happened? My best bet on why my front-end fried is having the HF vertical antenna coupled to the SA during a stormy night; even though the SA was powered off, there is no relay in the input to ground it.
