The Siglent SDG2042X Thread

[Bad_Driver]

Some UI house keeping would be nice. I’m now a owner of 5 (edit: 6!!) Siglent devices and there is not much in common in their user interfaces. And as shown in another thread every device software looks different on the PC and behaves different as well.
Come on Siglent, that can be done much better!

If someone can provide this last RB3 firmware I‘ll be very grateful  !

 Here's my copy, downloaded October last year.

Just remove the .txt off the end of the file name.

 Drat! I forgot about the 4000KB limit.

For those who want the B3 firmware get it now. Ik think the wetransfer link expires in 7 days.
If that happens, email me directly.

I got that B3 firmware after emails with Tautech. He contacted Siglent after my bug report and they fixed it with this B3 firmware.

That's the B2 firmware, right? Your PDF history file also describes up to revision B2 only.  B3 had not been officially released by Siglent, I believe.

I am lost in the long thread. Could you please remind me which bug B3 fixes? Thanks!

Look at fig 1 in the bug report pdf: Labview error using Siglents own example. That error has been solved with the B3 firmware.
Additional error still exist in the Siglents own example and has been solved by changing something in the labview schematic - see fig 2.

 Sorry! My bad. I'm afraid I got the 3B mixed up with the B2 part of the version number.

I measured the phase noise of the SDG2042X with the internal and an external reference. The plot with the external reference  (2. picture) looks like the plot with the internal reference at high frequencies, like the external OCXO below 2Hz and has strange spurs at multiples of 2.5Hz.

As the internal reference is 2.5Hz off the external reference, this looks like mixing products from the internal and external reference. Has my SDG2042X a problem, or is the insufficient offnes of the internal reference a "feature"?

[Blue]

Dear bnz,

Can you elaborate on how you measured the phase noise.

Thanks

[bnz]

Dear bnz,

Can you elaborate on how you measured the phase noise.

Thanks

Interesting,

how long does a single PN measurement in min/hours required.

While did some minutes ago some Jitter measurements using a LeCroy SDA.

While did some minutes ago some Jitter measurements using a LeCroy SDA.

It depends 
1.) on the FFT size, which is responsible for the resolution.
2.) on how low frequencies in the PN graph you need.
3.) how good your reference oscillators are compared to the DUT (i.e. how much averaging/crosscorrelation is needed to get your curve above the noice floor).

The above graphs were made  with FFT size 4k and took about half an hour measurent time to get sub Hz readings.

Anyway, the figures are IMHO too low...

Please tell, used feq. on SDG as sine or square and levels (asymmetric symmetric). Also used OXCO brand & figures sine or square/levels.

Measure also the Square output of the siglent as this should have Jitter (plenty off) and also the used OXCO against the PN OXCO.

In addition, you do not know how the siglent uses the OXCO signal: Direct or by PLL. May also use the FM / sine modulation with a freq. of 500Hz or 1kHz and with 1Hz deviation.

The Holme-phase-noise system seems to be accurate. See the cross checks with professional equipment on his web site. Also I was able to reproduce the specs of some of my OCXOs. Moreover If I turn PM-modulaion on I get a spike of expected magnitude in the plot.

The Siglent was set on 10MHz Sine 4Vpp (HiZ). I also did a test with 11.1MHz, it looked alike (for the external-reference measurement). The OCXOs were C-MAC CFPO-2, measurement below.

No I have no idea how Siglent uses the OXCO signal, but heavy oscillation with multiples of OCXO to internal ref frequency difference does look wrong.

P.S. the dark blue trace is the measurement of the DUT. The light blue the estimated noise floor.

[bnz]

I measured the reference in/output of the SDG2042X with a scope in the external-reference setting. There are indeed remains of the internal clock:  10MHz spikes of about 10mVpp (in 50 Ohm).

So is my SDG2042X defect or is that a feature, i.e. can somebody reproduce this measurement?

[luciof]

Connected the SDG2042X's 10 MHz In/Out BNC to the scope via a 50 ohm pass-thru terminator.
The first shot is in Internal Clock mode, and the second picture is in External Clock mode (like in your test); in this case it is an input, so I think it's quite normal to see some noise from the generator's circuitry.

[bnz]

Thanks for testing it 

Well it may be "normal", but it prevents to make use of the better phase noise performance of the external clock, to some extend. It's annoying as it is unnecessary that the internal clock is powered up at all, the latest as soon the external is connected.

[hpw]

Well,

using some 20Gs scope... as 50E input

A) signal as internal looks equal, not nice square wave

B) signal as externsl looks like a 1GHz sine at 10mV

So turtles stuff at HF limited..

Cheers

[bnz]

OK, I fired up the big scope ... for my SDG it looks alike my picture with its little brother.

Supported setting the output frequency after the completion of sweep
Counter add fast measurement mode
Changed the square waveform data used in square FM modulation

[SimpleXP]

Hi everybody,

I got a problem similar to the one here: https://www.eevblog.com/forum/repair/help-fixing-siglent-sdg805/, but with an SDG2042X. At some day, it just stopped booting up further the logo screen.

I already saved the boot log ouput via UART but I don't really know what the error at the end is telling me exactly...

I measured all hardware voltages, they are all as expected and the FPGA and Linux Heartbeat LEDs are blinking like they should.

I tried starting the sdg2000.app manually per nonsole but this ends in the same error, some configuration seems to be bricked.

I would like to try reflashing the firmware but I don't know how to do this via UART.

I would be really happy if I can restore this unit!

Hi everybody,

I got a problem similar to the one here: https://www.eevblog.com/forum/repair/help-fixing-siglent-sdg805/, but with an SDG2042X. At some day, it just stopped booting up further the logo screen.


I would be really happy if I can restore this unit!

Welcome to the forum.

We have recovery files to fix these.
Send us a PM with your email and we'll get this sorted for you.

In the meanwhile find a USB stick of 8GB max formatted in FAT32 with 4k clusters.

..........
And he got it fixed.

New firmware for SDG2000X models, as reported by NoisyBoy in this thread:
https://www.eevblog.com/forum/testgear/siglent-sdg2000x-firmware-hardware-software-versions/

Version： V2.01.01.37R3
39MB
https://int.siglent.com/upload_file/zip/firmware/Signal_generator/SDG2000X_V2.01.01.37R3_EN.zip

Release notes
Compatible with Rev.F hardware; if the hardware version is “05-xx-xx-xx-xx”, it will not support to roll back previous firmware version

My SDG2042x shows HW version "02-07-00-40-00", where should be the letter 'F' ?

I guess it's not compatible.

I'm guessing it's in the SN# coding.
Should have more idea after a reply from Tech support and after getting more stock of these in a week or so.
