Siglent SSA3000X and SSA3000X-Plus Spectrum Analyzers

[probe]

If you restore the serial number, you will loose the factory mode and all options it enabled.

If everything is working fine, stop messing around with it!

Yeah, you’re right (of course). I discovered that involves more than just SCPI’ing back your old number but that you have to generate a new serial number. Oh well, can’t complain really.

Again, thanks to all who made this possible. I wouldn’t have bought one with the availability of the “liberation”.

Now, that SDS2104X Plus looks mighty tasty, and I can convince myself I’ve outgrown my Rigol DS1054Z…

There was a comment somewhere in this thread indicating that the serial number that is on the back of the unit works just fine as Siglent has been mixing SSA and SVA serials anyway.  You would of course lose the licenses if you added back any serial number.

The SDS2104X+ is a mighty fine machine. I recommend it!

Brought here from another thread.....

Can someone please explain to me, what measurements are requir do for EMC? I might eventually add those to my software.

EMC testing is something I have never done, so I would need some assistance.

A wee overview is in the SSA3000X Plus manual on P134
https://int.siglent.com/u_file/document/SSA_XP_SVA_UserManual_UG0703P_E02A.pdf

The X Plus series has a dedicated EMI mode whereas earlier X EMI measurements are much more basic.
Typically their are bands of emissions that are of interest along with max permitted levels to meet the standards.
Their should be enough clues in the small EMI chapter to get you started especially with the ability to set the limit levels and the modest frequencies EMI measurements are done at.

Many thanks all for your support!

It was a long journey, but I finally received a replacement power supply last week. The SSA3021x has sprang back to live and is working as can be expected. It took more than 3 month to get the spare part. This was not due to lacking support from Siglent China, but mismanagement of my order by the Australian Siglent distributor. I ended up ordering the part online from Siglent Europe. They had this part in stock at 50% off the quoted price in Australia which included postage. It took 3 weeks from order to delivery (Netherland->Australia). Not bad under current circumstances.

On a positive note, it gave me the opportunity to add a header to the UART port and re-enabling the telnetd service for remote access running on firmware 1.3.9.7 on HW 07.03.00.

I read in the thread that i need to buy a SSA3021X+ to upgrade it to a 3.2GHz SVA like the SVA3021X.
What can the SSA3021X be upgraded to?
Sorry if i missed this info in the thread.

[tautech]

What can the SSA3021X be upgraded to?

SSA3032X

[Echo88]

As a non-RF-hobbyist im really struggling wether to get the Plus version of not, since i cant figure out wether i would really need the Vector network function in the future.
Is there any usage for it apart from measuring antennas and related RF-stuff?

[Bicurico]

It's a no-brainer. Get the Plus model. There is little price difference and the Plus model offers more functionality and a touch screen.

[tubularnut]

… and ability to use mouse and keyboard too.

[Bicurico]

Measurment-wise you get:

The basic function of the Siglent SSA3021X PLUS Spectrum analyzer and options include RF power measurement, vector signal modulation analysis, reflection measurement, and EMI testing.

For me the most significant different is that the Plus model offers analog/digital modulation analysis.

On https://www.siglent.eu/product/1140903/siglent-ssa3021x-plus-2-1ghz-spectrum-analyzer-free-tg-license you can see pictures showing the QAM Constellation Diagram and decoded Bytes map. You don't get this on the regular SSA3021X Model. I would swap my unit for the Plus model anyday if I only had to pay the difference.

Vitor

[Bicurico]

Just to reinforce it: the price difference between a SSA3021X and SSA3021X+ is about 150 Euro if I am not mistaken.

That is the cheapest "upgrade" on any of the available options!

Plus you can really hack/upgrade this device into something even more versatile: a SVA1032.

Vitor

Alright, you convinced me. The SSA3021X+ should arrive saturday

Hello,
has someone already tested the new version of the firmware (V3.2.2.5.0 - Release Date 12.03.21 ) for the SVA1000x plus? Will all options and modification remain?

best regards,

Yes, all options etc remain.

Just updated my SVA which started life as an SSA+ to 3.2.2.5, all options and upgrades appear to still in place.

Hello gents,

I think i screwed something up!

I tried the SSA3021x plus to SVA1032 cross flash, which worked. I noticed that the calibration issue was problematic, so i decided to revert back.
I have a full backup on my pc ( done with ads backup ).
After reversing the cross flash my unit now says that it is a SSA3032X plus, while it is not. Unfortunately i lost telnet ability.

Whatever script i try, i cannot get telnet access. Further, my keys for TG ( and more options ) were permanent and are now counting down from 130 hours.
My serial number is present and displayed.

I am on 3.2.2.4.0

Who can help ?

Which telnet scripts have you tried? You most probably messed the ProdID. Do you have any idea of what you inserted there or what you might have missed when editing?

I have described, in this thread, a crossflash method that is foolproof but people continue to go the long way of linux editing where the risk is higher.

They keep forgetting the that everyone is a linux geek until access is lost (in a sealed machine)...

Just received my 3021x Plus FW: 3.2.2.5.0.

I can confirm that the backup and telnet scripts work, however the unit won't accept the SVA1032X firmware versions 3.2.2.4.0 or 3.2.2.5.0.
Once the update runs, it just goes back to the update page (no restart or anything).

Does anybody know how to downgrade from this version?

Thanks!

[fugazi]

Hi All,

I had success in getting the unit back to functional. Used the UART to log in and found that i made a stupid typo in the device id.
So, no telnet script would have run in the end..

I tried to revert back from the cross flash because of the calibration issue of the Vector Network Analyzer. From there, it went wrong.
With a TTL usb cable i was able to login and restore the mistake. I am still in PRO mode and i will not revert to the SSA, too much risk ;-)

Big shoutout to TV84!

I found a LabView driver for the non Plus SSA3000X instruments, so thats a good start programming the SSA3015X Plus even though some functionality is missing (like THD).
Now trying to setup the tracking generator there seems to be one SCPI command missing in the documentation… I cant find how to store the trace to ref command thats needed before I activate the normalization. Has anyone a tip?

Hello,
after upgrading my "SVA1032X" to 3.2.2.5.0.r8, I experience some issues with the VNA, SA not tested so far.

1) When being through the calibration procedure (e.g. 1-port-cal) the "apply calibration" is "on", but garbage is shown on the screen. Cal status is "C?" - see Pic 1. After Switching it to "off" it seems to be working, see Pic 2 of the calibrated load. But it shows "---" in the upper left corner for the cal status.

Did I misunderstand something or is this a bug - somebody else run into the same issue?
   
   
2) If I switch on e.g. 10000 points for the VNA stimulus the calibration is only performed and working with max 751 points. Unfortunately are some values in between not - or not correctly - approximated. See pic 3 & 4 which are showing the same 50 Ohm load at identical frq. and span, but with 751 points vs 10000 stimulus. Pic5 is zoomed into 0.1-200 MHz .

3) Maybe I am missing there something, but if I use "User1" as cal-kit, the delay I enter seems to be ignored.


Thanks,

Juergen

Hello,

I suggest you to post to the sibling thread on the SVA https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/725/

1) When being through the calibration procedure (e.g. 1-port-cal) the "apply calibration" is "on", but garbage is shown on the screen. Cal status is "C?" - see Pic 1. After Switching it to "off" it seems to be working, see Pic 2 of the calibrated load. But it shows "---" in the upper left corner for the cal status.

Didn't understand what was on the input ports during those measurements. However, it remembers the bug in "pro mode" being discussed in the other thread for release 3.2.2.4

For the other two points, I will check on my unit.

[DL4JY]

Hi,
what I found out to 2) :  If you change the no. of points in the calibration menu (when asked to apply the open standard) by touching the points (751) on the screen to e.g. 10000 - calibration will work for the number of points selected. However, it jumps back to 751 point frequently.

Regarding the PIC1&pic2 attached, they show the same 50 Ohm load, used for calibration.
