Siglent SDS2000X Plus

[tautech]

I saw a joke earlier in this thread about screen protectors and bubbles. Just received my scope from Saelig and I removed the screen film installed at the factory that had a red tab and said remove before use. However, my screen seems to have another film installed on it and in this one I have bubbles.

Is there a second protective film that needs to be removed or do I have an issue with my screen?

See photos. Scope is brand new just opened.

Maybe 2 were installed by error. 
There is matt glass underneath so at the edge of the display use a spudger tool or similar to get under the remaining film to remove it.

I received my in middle of 12/2022 and it had the same issue. At first I thought it’s defective display, but shortly I realized it’s 2nd layer.
I used toothpick to remove it.

Thank you Martin72, tautech, and MarkusAJ for the replies. I’ll try to remove it.

[BillyO]

Hmm, mine had only one.  I suppose it's possible that 2 got put on there.

I have one of these devices as well (SDS2104X Plus). But now it just stopped refusing to boot and just hangs after doing a bunch of self tests at the SIGLENT logo. (If you are curious, youtube video here: )

Is there any reset everything or safe boot, these devices support or should I just send it back for warranty?

[2N3055]

Shutdown the scope and on next boot keep pressing Math button quickly and persistently...

Thanks that helped!

I've only heard of this with older firmware.

When comparing the 10MHz output of my reference GPSDO to my SDS2042X Plus SDS2104X Plus, there is a significant frequency deviation.
Is there a way to "tune" the internal reference oscillator of the SDS2000X Plus (similar to the DAC-value for the VCO in a SDG2122X)?

Pics please...
Can´t be said enogh.

Significant?  Mine is off by about 3Hz once warmed up.  What is significant?

It's off by about 1 Hz which for my applications is significant.
However... no matter how much off it is, the question is if there is a way to calibrate it or not.

SDS2042X Plus?  Are you mixing model numbers?  Assuming you are referring to an SDS2104X Plus or one of its siblings, is the discrepancy between your GPSDO and the output of the built-in AWG, the hardware frequency counter or the screen display frequency counter?  Or something else?  I'm not aware of any way to adjust any of those in any case and the scope does not have an external clock input.  I doubt any model without an external clock in will give you precision better than 0.1ppm.

Sorry, you are right... I mean the SDS2104X Plus - not the SDS2042X Plus.

I assume they use the same clock source for the scope and the AWG since both show the same deviation.

[BillyO]

I assume they use the same clock source for the scope and the AWG since both show the same deviation.

So, if you feed the AWG into the scope 10MHz shows as 10MHZ right on?

[rfspezi]

Correct.

Dave did a teardown here:

I don't see anything that is tweakable with a screwdriver.

Correct.

If I may ask, what application is that?  That needs   better than 100ppb timebase accuracy on a scope?

[bdunham7]

I don't see anything that is tweakable with a screwdriver.

Not likely to have a trimpot, but it may have a DAC/VCTCXO combo like the SDG2000 series that is used during initial setup and perhaps there is even a calibration routine for it that we just don't know about or have the commands for.  I doubt you could count on its mid-term stability to be better than 0.1ppm though, so I'm not sure how much closer you could get.

Can somebody confirm that the lowest start/stop frequencies for Bode plots on the SDS2000X Plus series are:
Start = 10 Hz
Stop = 510 Hz

[tautech]

Can somebody confirm that the lowest start/stop frequencies for Bode plots on the SDS2000X Plus series are:
Start = 10 Hz
Stop = 510 Hz

Stop frequency = highest your AWG can provide up to 120 MHz max.

[rfspezi]

Stop frequency = highest your AWG can provide up to 120 MHz max.

The lowest possible frequencies, not the highest are in question.

[tautech]

Stop frequency = highest your AWG can provide up to 120 MHz max.

The lowest possible frequencies, not the highest are in question.

Start = lowest.
Stop = highest.

This is used for Bode plot and analysers universally. Stop = highest.
What do you need to know ?
Start to Stop = a frequency sweep.

Edit to add:
From the datasheet:
Bode Plot
Frequency Mode: Linear, Logarithmic
Range: 10 Hz ~ 120 MHz

[2N3055]

Can somebody confirm that the lowest start/stop frequencies for Bode plots on the SDS2000X Plus series are:
Start = 10 Hz
Stop = 510 Hz

You can create scan from 10Hz to 510 Hz.
Actually, min span of scan is 500Hz.
So 10-510Hz or 2000-2500Hz etc..

You cannot create scan from 10Hz to 20Hz if that is what you need.
