Hack of Sigllent spectrum analyzer ssa3021X?

[analogRF]

Successfully modded on FW 1.2.9.1 with no issues. Follow post # 428 (or # 460 which is the same...)
However, there are a couple of things which I hope this is the right thread to discuss it

How does your 1Hz/3Hz RBW look like? I mean how do they behave?
Look at the attached photos I got for 100MHz CF and Span of 1KHz.
Clearly these RBWs are just digital filters (not actual bandpass filters like those old agilent SA which didn't go below 1KHz or so)

So it seems 1Hz and 3Hz RWB are just "heavy" averaging methods. But the noise floor is just a flat line. Is this the right behavior?

Also note that the flat noise floor is a couple of dB HIGHER for 1Hz RBW than 3Hz?!

Can someone confirm this? I have tried other center frequencies and it is the same

of course your span should be very small otherwise it will not accept 1Hz or 3Hz (sweep time will be out of range)

another issue is a small bug I guess, at power up, at the bottom line it shows center frequency (left) and stop frequency (right)! instead of showing the span (I use a USER defined power up state with CF and span)
can someone also try this?

thanks

EDIT: If I choose "Last" state as the power up state, again after turn on it shows center frequency and stop frequency rather than span. I think it should be fixed in the next firmware

EDIT: dug around a bit more and found the answer (kind of) in other threads. according to Siglent this is normal. you need to have input signal at those RBWs and then you will see the correct (somewhat) behavior. But the small bug (showing CF and stop freq together) remains

I have posted this observation few months ago in the Siglent support
thread in this forum.

No one seems to care about this realy.

Received today my SSA3021X and it has the SW1 version 1.2.8.5a with HW version 07.03.00.
By going thru the topic it seems it can be upgraded without too much of a hassle.
But that is for the IT expert of course....

Would there be any of those experts willing to remotely assist with this upgrade?

Tnx!

I can crash my SSA3021x when entering e.g. "868"+"Enter" immediately after it has booted.
After that it does not resond to any key anymore and the display stops updating.
The only way to get it working again is to powercycle it.

Is that bug a result of hacking it or is this "normal"?
SA is running 1.2.8.5a FW version.

I managed to do the SW upgrade to 1.2.9.1 without problems.
Furthermore I tried to get the hack done following #428 and #541.
The result is that the SA is still showing the original version with only the (already free) TG active.

When looking at the folders I see:
SA backup
nsp_data_b
NSP_sn_bandwidth.xml
nsp_data_bx
NSP_sn_bandwidthx.xml
NSP_trends_config_infox.xml

SA-firmdata0
nsp_data_b
NSP_sn_bandwidth.xml
nsp_data_bx
NSP_sn_bandwidthx.xml
NSP_trends_config_infox.xml

I assume because the original files without the "x", the hack didn't take place yet.
How can I remove the original files in both folders.
nsp_data_b
NSP_sn_bandwidth.xml

Thanks for advice!

My Telnet adventure worked out well in the end....phew 
I managed to remove the files without the "x" on the end by means of the rm command.
After reboot the SA came back with all options permanently active.

I am wondering if i should change the root password of the device? After all it is a public know password.

Of course my LA is not accessible from the I-Net (protected by firewall) and it is not an interesting target for a hack (as most of the time off).

But you never know. Has anybody tried changing the root-password already? Using the passwd command?

P.S:
I got my unit yesterday and flashing latest FW and applying the hack was straight forward - thank you!

You'll be able to change it for that session BUT, once you reboot, you'll get the original as the CRAMFS is RO. (If I remember correctly.)

Folks,

I have a SSA3021x w/ v1.2.8.5a firmware (HW 7.03).   It's already modified.    If I want to upgrade to 1.2.9.1, do I need to reverse the modification process before applying the upgrade?    Or can I just update the firmware with the patch already in place.    I've read the the last two pages of posts but it's not entirely clear.

It is, just one page further back in reply #490.

Hi,

I have a SSA3021X which I upgraded to 1.2.9.1 and then modified to get all options. I did this in beginning of July and it worked very well (with all options enabled) until today. Now when I switch it on, both TG and Mode key are lit, then it shows the Siglent Logo, then after some seconds TG and MODE are switched off and ... that's it, i.e. Siglent Logo stays on screen, no measurement screen occurs.

Of course I did try to login via network, however the device does not request an IP from my DHCP. So it is NOT reachable via network too.

Any suggestions on what to try ? Are there any undocumented key combinations which allow to reset, get a console, or something ?

Please help, I'm stuck. The device seems to be bricked...

Thanks
Chris

You can connect the serial port (console) and investigate the boot process.
From your description it could be a NAND-memory error. I had similar symptoms on my analyser after a firmware update.

A restore/flash of a NAND partition would be possible.

Now you need to navigate on page 9 and try the same steps

I did rebuild once my SDG2000X using sdcard repair...

Hello all,

Thanks for your help in advance.
I just bought a SSA3021X, the software is 1.2.8.5a. When i telnet, it say connection refused.
Does any one have the same problem and how can i login the machine?

Thanks

Read.
First this:

and there follow msg links and read more, all what you find.
There is not free lounges. It need work. It is, as usually, first brain (read, study, try understand), then muscle (connect to machine and make what needed).  If you just start "try this and that and test if you have just good luck" only you get is big hassle or even "bricked" SSA..

Hi, thank you very much.
By some reason, my putty put the port of 22. Now all working fine

Hi,
Sorry for my newbie question, but it's the first time I connect a device to pc through the Ethernet port.
I have an SSA3021X with the following config:
SW1: 1.2.8.5a
SW2: 20170512-1
SW3: 000000D1
HW  : 07.03.00

Unfortunately it doesn't seem to connect to my laptop (I have Win10).
The procedure I followed:
connected the SSA ethernet port directly to my laptop Ethernet port through the cable,
the SSA static IP address is 10.11.13.220
Submask: 255.255.0.0 (same as my laptop ethernet card)

Control panel shows "unidentified network",
If I try to ping 10.11.13.220 from CMD I get:
connection timed out,
4 packets sent, 4 packets lost (100% lost)
same thing with PuTTY.

On the rear of the instrument both LEDs are lit (green and orange)

What am I doing wrong? 
thnx

Welcome to the forum.

I strongly suggest that you get your firmware up to date to the current version: V1.2.9.2a
All the later FW versions are here:
https://www.siglenteu.com/service-and-support/firmware-software/spectrum-analyzers/#ssa3000x-series

Each version comes with a changelog file and installation instructions.

Hopefully that will fix any connectivity issues you have.

BTW, this is the main thread for these spectrum analyzers:

Connecting the PC directly to the DSO through ether requires a crossover cable. Are you using one?

I have never seen this level modern laptop what accept win10 and still need crossover cable. Mostly today these have AutoCrossOver. AutoCrossOver have been available 20 years and today most machines have it.
But yes of course all is possible.

Your subnet mask... do you really need network for up to 65534 IP's when your whole network is one PC and one SSA.

I think class C network is well enough for 2 machines private "network". (direct cable between laptop and SSA)
Subnet mask 255.255.255.0   (this accept one octet of addresses for hosts because last 8 bits in mask are zero)
And it is private network so is it quite common to use example 192.168.0.x
and x  between 1 - 254  (address 0 and 255 do not use)

In some cases also firewall may have role with problems.

If your laptop really do not have AutoCrossOver LAN then you need cross over cable. If it have AutoCrossOver then both cables can use.

[tv84]

My crossover suggestion was based on the " both LEDs are lit (green and orange)". I assumed solid lit.

My crossover suggestion was based on the " both LEDs are lit (green and orange)". I assumed solid lit.

There is so many kind of lights..  example my PC redorange is constant and yelloworange is blinking when trafic and SSA green continuously and yelloworange blinking when trafic. There is not tight standards for these lights. In some cases led color also tell speed... 10/100 or 1000

But how ever I will recommend class C network in this case.
Class C IP addresses range from 192.0.0.x to 223.255.255.x.
Default subnet mask for Class C is 255.255.255.x

@pri:

One example:

Download puttytel.exe  (select right version for you) here https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

It do not need any kind of installation, just run

But first:
This is only for direct connection so that PC LAN port --- cable --- SSA LAN port

Set your PC LAN and SSA as in images and run puttytel.exe and enter address as in image and open it and you see puttytel console as in image. If not then your LAN do not work.  Check that your PC do not restrict this communication or if your cable is ok. Sidenote, in this case this default gateway is just dummy... but some systems are happy if there is something and also in some other cases subnet IP address range bottom is nice to use for this.

Images do not need explanation and perhaps if these are clear for you still they may help some other peoples.
(of course there can use more common 192.168..etc what are many equipments "default" but example my system have some other things also so 222 sure do not make collision...

Just like 1, 2, 3, 4,....  and then enter what need...

(you can set puttytel (telnet client) so that it do not forget every time all and also good practice is set it so that it keep log about all what have done with console so that if something goes wrong you can inspect log.... or show log to some other people if need some help)

It worked as you suggested!

Is this message still valid to upgrade vers. HW 7.03 ?
