New Rigol DS1054Z oscilloscope

[kerrsmith]

I received an email (in the UK) yesterday and was told mine was arriving today, they had a batch flown in directly from China and were sending them out straight away.

All these units will have new firmware in them I was told on the phone when I called to check about the knows bugs and that the scopes are now fixed regarding the AC coupled trigger mode and the jitter issues.

This post from the jitter thread implies things might be different than what you were told.

[kerrsmith]

Yes, I have just read this - I put a similar note in this thread as that one just in case someone was not reading all the threads (there is a lot to read if you start from the beginning of all the threads).

My scope did not arrive today as the courier decided to leave in their depot all day and not deliver it unfortunately (after emailing me to say it was going to be delivered today and to make sure I was home to sign for it).

Once it arrives (Monday hopefully) I should be able to see what firmware it has.

I will have all weekend to get excited now - I have been waiting ages to get a new scope (maybe I will spend the time reading the user manual)...

I finally got my DS1054Z. I of course want to unlock the extras but I can't find any site with the code generator that is still alive or has a working generator.

rigol.3owl.com is down, so is another site, and goroot.ca does not produce a working code.

I have tried to find links and references here on the forums, but it is an ocean to swim. Any help please?

BTW, my software version is 00.04.02 SP3, Board version 0.1.1

I can confirm that. Mine arrived yesterday. The code generator does not work for 00.04.02 SP3. The jitter problem seems to be solved by this firmware version.

[Lightages]

The code generator does work, eventually. Try closing the web page and retry the code generation again. It generated a different code for me after the 5th try and it worked.

I have not had time to test the jitter problem yet.

The http://gotroot.ca/rigol/riglol-103d/ mirror site is also still up and running.

Working:
http://gotroot.ca/rigol/riglol/

There is source code on the bottom of the page. In the zip you can find html+js and compiled version for windows or linux. It better to have off-line version just in case.
Keygen should work on new firmware. Keys not depend on FW, I think.

That's the same board and firmware version in the DS1054Z I had, and it had the jitter problem.

Based on the testing over in the jitter thread from a bunch of users, we know the severity varies.  I'll bet you got one where the PLL isn't as unstable.   (Assuming, of course, Rigol is being honest and consistent with their version numbering...)

You can do the sample clock test to find out if you're curious.

But if you can't see it and it's not interfering with the type of testing you want to do, I guess it's you're lucky day.

Did you ever apply the beta FW? If so, did you bad results like poida_pie and me?

I loaded the beta, but I didn't have results like you two.  Besides ending up with a randomly locking keypad on boot, I got this with the beta:

I thought it was fixed at first, but if you read on we determined it was not:

Well, after some more testing it seems that I was wrong.

Thx @Lightages for your feedback! I tried with another generated code and all worked fine.

@MarkL: I was not that lucky after all. My initial tests were only for frequencies upto 1MHz. Today I tried again on a signal of 10MHz and the jitter was clearly visible after I switched the trigger coupling to AC. I have attached a picture of the signal on the DS1054z and the same signal on my analog scope. I will do some other tests on higher frequencies and post the results.

[beNative]

ok, I did now some more tests on frequencies > 5 MHz.
In general it seems that the jitter problem is not gone, but it isn't quite as substantial as what was reported earlier in this thread by other users. On my DS1054z which arrived last friday I did not notice the jitter issue when tested on frequencies up to 1MHz.
Today I hooked up my poor man's frequency generator, a AD9850 board which can generate frequencies up to (a noisy) 40MHz.
First some pictures of the rigol with/without AC trigger coupling + signal on my analog scope @10MHz and then the same with a (noisy) signal of 40MHz.

As you can see @10MHz I have jitter with both DC/AC trigger coupling. Maybe the first is just noise generated by my AD9850 board but it is not visible on my analog scope supplied with the same signal.
At 40MHz I saw almost no difference between both settings on the Rigol. On the analog scope the signal did also show up quite noisy.

@MarkL are these results consistent with your findings about the source of the jitter problem? Let me know if there are some other tests I can do to help.

The problem I was referring to is the 5us jitter.  The AC coupling jitter has more consistent behavior scope to scope, and should be correctable with new firmware.  Take a read through the jitter thread in blog #683, and if it's not clear what the difference might be between the two, watch Dave's blog #685 on AC trigger coupling.

What I meant by you being "lucky" is that the 5us jitter is dependent on component variations and your PLL either managed to lock, or is just not unstable enough to be visible in the time domain.  If it's working well enough for you, you're in luck (although we know temperature affects it also, so hopefully it your scope will stay that way).

A more detailed sample clock test, which is the origin of the 5us jitter, can be performed:

You can use Alessandro's program to do an FFT.

And also, it looks like your trigger might be set at the peak of the waveform, which is causing some of the randomness in the last couple of shots.

If you want to dig into the jitter issue, you might want to hop onto the jitter thread so we don't have another parallel thread going.  (Not that THAT ever happens...)

Something is either wrong in the previous setup (beNative) or mine. The 2 pictures are of a 10 MHz and a 50MHz sine wave fed to my 1054z thru a 50 ohm load. There is no difference in AC or DC coupling. The Signal Generator is a HP8664A set for 0dBm output.

Thoughts? Notice the difference in time settings.

It is not clear that your analog scope is showing the waveform after 6uSec Delay.

[avvidclif]

In response to a PM. AC or DC Coupling had no effect. However Edge triggering with AC trigger showed the following. If I go to slope Trigger it will not allow AC Trigger but goes to DC and shows a correct image.

I quit. By careful manipulation of the Trigger I can get a bad or a good image.

I don't know if there is a problem or not.

Can anyone confirm the highest frequency the hardware counter can read? It appears on my DS1054Z hacked to 100MHz reads to 112.999MHz and then starts aliasing any higher. My DS1052E will read at least to 480MHz with the tests I can perform.

The software counter reads correctly.

There appears to be no spec listed for the hardware counter.

I would not be surprised if the DS1xxxZ's "hardware" counter was done by FPGA based on the ADC's output instead of dedicated edge detection and counting hardware.

Seems to be related to the amplitude of the signal rather than a sampling problem. If you adjust the vertical so it is clipping/off the screen, it will go higher before skipping counts.

So you have tried this? I did make vertical attenuator adjustments but I never got over 112.999MHz indicated.

Does anyone know how to set the realtime clock of the unit? The reason I ask is that all files that I saved so far with this scope are dated 1/01/1980 and I couldn't find a way to adjust the date in the settings. Did I miss something?

There is no real time clock on the DS1000Z series scopes.

Really? Can others confirm this?

Yes I can confirm the DS100Z series does not have an RTC. It is one of the reasons I mostly use Ultra Sigma to capture the screen.
(That is until Marmad publishes a DS1000Z version of RUU  )

As for the frequency counter: I am almost certain my DS1074Z does not have a "real" HW frequency counter like my DS2072A has. It looks like above 100 MHz the DS1000Z counter gets lost (I first suspected some sort of aliasing wrt 125 MHz, but it seems more complex than that)
