Siglent SDS3000X HD and upgraded SDS1000X HD

[skander36]

After using the LA license, it was only reduced by one day.
Then I used CAN FD and only this was also reduced by one day.
However:
If the trigger is still set to e.g. CAN-FD and you restart, this is regarded as usage and is deducted accordingly (made after the pictures, therefore not visible on them).
So always deactivate both (decoder and trigger) before shutting down/restarting the scope.

I don't understand, 3000X-HD is not crackable? Why are you making worries about trial licenses?

Why are you making worries about trial licenses?

I'm not, I was just reacting to egonotto's posts.

So it is or not? ...

[kripton2035]

it's like the 2000xHD...

[skander36]

it's like the 2000xHD...

So it it's not?
Otherwise why they were talking about the trials number remaining?

Hello,

So the bug has already been fixed with 1.0.3.3. An older version was probably installed earlier. I wonder when the bug for the SDS2104X HD will be fixed.

If we need an option at work, we have to buy it and all companies have to.
Being able to test the options sufficiently beforehand is not uninteresting.

Hello,

I just wanted to compare the noise of the SDS3034X HD with the Micsig MHO3 (in the Micsig thread). There were some strange problems. Although there was no signal, the measurement showed nonsense. Only switching the SDS3034X HD off and on again solved the problem.
During my measurement, the strange message "CALIBRATION_COMPLETED" appeared. However, the measurement was not disturbed by this. Unfortunately, I did not catch this message.

Read the manual, there might be an auto-calibration feature. Probably an option to enable/disable it somewhere.

[Martin72]

Hi,
I know this message...
It is not described in the manual and appears about 10 minutes after booting.
If this "secret" calibration has no major influence, the message should perhaps be removed to avoid confusion.

Have you checked in the settings for any type of auto calibration? I'm sure you've seen other scopes that randomly auto-cal.

[Martin72]

I'll have to see.
With the 2000X HD you could set something so that a calibration was carried out after every vertical scaling change.
But that was adjustable and short and not 10 minutes.
We mustn't forget that the 3000X HD is in a different league in certain areas, closer to the (now) former top model 6000, I wouldn't be surprised if it has the same ADCs as the 6000, just 2 instead of 4.

Hello,

the bandwidth of my SDS3034X HD is about 420 MHz.

[pasha]

Can you please make a demo video for sds3000x hd.

[Martin72]

What do you have in mind that should be shown in such a video?

a small example with bode plot performance and fft, i have never seen its interface other than introductions. thanks.

Hello,

I have now tried the digital channel. I can't get the promised 100 Mpts/ch. A maximum of 50 Mpts. With the analog channels I also don't get 400 Mpts with only one active channel when digital channels are activated.


Best regards
egonotto

PS: When I set the trigger to an analog channel, I got the promised 100 Mpts.
PS: Strangely, at 10 ms/div I have 100 Mpts and at 5 ms/div only 50 Mpts with Fixed Mem.

[Martin72]

Hi,

I got the promised 100 Mpts.

The data sheet states 100Mpts (funnily enough per channel, we have 16 digital channels), but it doesn't say anything about having them under all conditions.
However, it also doesn't say when not.
I wouldn't quite trust the data sheet:
The 1Ghz model says 800Mhz limitation, the manual says 750Mhz...
Perhaps Siglent should check the data sheet again and correct it.
By the way, Batronix now has the 500Mhz and 1Ghz in stock.

Digital traces are different to those reconstructed from the analog channels.
They are contrived from digital levels exceeded from the bus voltage settings and show no additional data.
H, L and the transitions between are just straight lines so the need for many data points is much reduced and more related to capture length.

The acquisition rate of the digital channels is "only" 1 GSa/s. The scope simply cannot collect more than 50 MPts in the 50 ms sweep time you get at 5 ms/div, I'd say. At 10 ms/div the number of captured points reaches 100 MPts, so memory size becomes the limitation at slower time bases.

Hello,

however, the same argument would also apply to 50 Mpts and perhaps 1 ms/div. But then we have the 50 Mpts and not just 10 Mpts. There is undoubtedly still a small error.

In the picture we even have 50 Mpts at 5us/div. Why isn't 100 Mpts possible?

Hello,

With segmented memory, the number of segments does not appear to increase if only one channel is used.
For example, with 1 Mpts I have 159 segments with one active channel or with four active channels. (SDS3034X HD)

That's only natural:

In full channel mode (both channels per ADC activated) and 1 Mpts per channel you use up 2 Mpts per ADC for each acquisition.
In half channel mode (only one channel per ADC active) the record length automatically doubles to 2 Mpts in order to cover the same time span (in half channel mode the sample rate doubles as well after all), so the total memory usage reamins the same, therefore also the number of segments.

[egonotto]

Hello,

I don't understand. I have always set 1 Mpts. In the case where only C1 is active, why not use the memory that is available when C1 and C2 are active?

I forgot that SDS3000X HD is quite a bit different when compared to the SDS2000X HD. The SDS3000X HD has 1 x 400 Mpts shared between all channels, while the SDS2000X HD has 2 x 200 Mpts, i.e. 200 Mpts per ADC. SDS7000A behaves the same, with the only difference that it is 2 x 1 Gpts instead.

The SDS2000X HD and SDS7000A behave like I've described, i.e. whenever both channels in an ADC are active, then the record length gets halved and the total memory remains constant.

SDS824X HD has shared memory 1 x 100 Mpts and acts as expected, i.e. a certain record length for single channel, half the record length for any two channels and a quarter of the record length for more than two channels.

For both architectures, total memory per ADC is always the same and number of History frames remains constant.

I can't check the SDS6000 right now, which has 1 x 500 Mpts and is therefore comparable to the SDS3000X HD. But even architectures with single memory are still different with regard to ADC: SDS800 has 2 x ADC and 1 x 100 Mpts, SDS3000X HD has 2 x ADC and 1 x 400 Mpts, SDS6000 has 4 x ADC and 1 x 500 Mpts.

I would expect the SDS3000X HD to behave exactly like the SDS800X HD - the screenshots above just don't show the true picture. The scope is still in Stop mode, hence any altered configuration cannot become effective. For each different setting (1, 2, 3, 4 channels active) you have to ensure that the scope is in Run mode, i.e. close the history first. Then you should be able to see the true record lengths. Furthermore, to be absolutely sure when checking the maximum possible number of frames, click on the "Frame No." field in the History and then on "Max" in the numeric input pad.
