Dave tries out the new DS1054Z firmware from Rigol that is supposed to fix the 5us delay jitter issue, and the AC Trigger Coupling jitter issues.
Have they fixed it, or is there still a problem?
What caused the 5us jitter issues to begin with, Dave also investigates the ADC PLL based sample clock with an e-Field probe and the Rigol DSA815 spectrum analyser.
Did Rigol also change the PLL coefficients?

I've used that PLL before, and it's pretty important that the two L1 and L2 filter inductors are mounted at 90-degrees angle from eachother, at least when they are close to eachother. You will notice this on Figure 26 of the datasheet, how the inductors are rotated. I noticed how they are sitting right next to eachother on the Rigol board. This will account for some of the phase noise.

@user-oy8cs5pu8b Жыл бұрын

Is it a good way to desolder inductor from pin 9 (5:31) and turn it parallel to ics case? It can be connected between pin9 and pin8. Is it critical that gnd path will differ between L1 and L2 pins inductors?

Man by far this is the best video yet. I must admit it was mighty impressive from Rigol's side, they are filling a gap in the scope market value per unit and yet staying out there with the client as issues turn out. That is very cool after market attention to detail.

For what it's worth, I got my DS1054Z about 4 weeks ago and had some some jitter with the AC-trigger-coupling but mucho mucho jitter with the 5us delay. I updated the firmware (from original 00.04.02.SP3 to 00.04.02.SP4) and the AC-trigger-coupling jitter is still there (a little) but the 5us delay jitter went completely away! Excellent, excellent video Dave. I'm a new viewer.

Sounds somewhat similar to an issue I had with an analog devices DSP that would at certain temperatures begin to have internal PLL jitter issue. It took forever to chase that down. In the end the problem was insufficient decoupling capacitors on the power rails for the DSP that was running at it's max frequency. The problem would only show itself when we put the product in a thermal chamber to verify its function over our required temperature range. There was only a narrow temp range where it would jitter.

Wow great content! Thumbs up for showing the waveform before and after the fix. However I'm not so sure that after the fix their clock is as unclean as you say considering that you picked up the signal remotely from the tracks around the loop filter. Even under those conditions we saw 37 dB SNR. To get the real figure you would need to electrically connect to the chip output with proper termination.

@tubical71 9 жыл бұрын

That´s why we only get 37dB SNR, as rigol failed to set the termination and/or the right trace lenght in order to get a propper SNR in first place. If you look to the signal prior to the new firmware, it was even worse....And this is as good example why HW-design is important, as you simply can´t solve those problems right by SW-tewaking only. If they had used a single smith-diagram for that trace lenght/termination issue/reflection rejection, they would have known this prior to a single trace routed the wrong way, or having the wrong component value within that curcuit between pin 7/24 at 05:34.....

I do not agree here, as if rigol had checked the overal RF output, they would have spotted their awful clocking source by themself. Not to be detected by the customer, but this is how pretty much every company solves their problems nowadays. When i worked as a design engineer some ten jears ago, i done some prototypes, reworked it (or them), until they met the design center values. This takes time and money, but if you need to put out rock solid working units to (co)operate with some others you need to be sure, that your thing is working 100% within its specs.

@heinzk023 9 жыл бұрын

TubiCal It is quite simple to say: "How stupid could they have been not finding that PLL glitch". My experience from working at a software company is that this is most often the result of mulitple unfortunate accidents, maybe even quality issues with the parts used (caps, resistors). And for every glitch that makes it into the final product there are 100s they have found early enough. And we must not forget that RIGOL products are low cost, they can't afford to rigorous QA regulations as in medical or aviation products. They were lucky being able to fix it in software - to some extent.

@tubical71 9 жыл бұрын

They need to test their products according to meet the FCC and VDE specs and there are many, many tests according to RF as well including electromagnetic emission and its propper shielding, they must have gone trough this with their eyes closed, not seeing this bad clock. As a bad clock design is usually a source for huge and/or high RF emission as well... Just take a look at the upper harmonics of that clock when Dave shows the spectrum of the original clock signal´s E-field the H-field might be even worse.... Sorry i do not see any evidence, to proove something in order to forgive rigol anything here, as they are a company which their #1 reason is to make money.... If they, at least, have something like a minimum quality test and/or some final inspection, they had spotted this issue right away themself anyway....

I can't count the number of times I've left the faraday cage with that thing set to single trigger, leaving the last sweep up for quick reference, reworked some aspect of my circuit and have come back to a pretty plot of the instruments noise floor. It's a real pisser. I'm also a bit sore about the lack of log frequency scale...considering the broken HP it's replacing costs $9k used I guess I can't complain too much. It's also a lot more portable so it can be moved out of the cage and onto the bench for near field probing and such.

PLL is everywhere, even my 30-od year old direct drive Pioneer turntable motors use PLL to keep the speed steady, it's surprising that for the age of PLL, they didn't check it properly to make sure they were timing it right, it's like a clockmaker building clocks and not actually checking to see if they actually keep time properly...

Dave, the spurs of the PLL output may look a little bit odd compared to your idealized frequency domain "spike". A few years ago, AnalogDevices published a great set of notes relating "Timing Jitter" & "phase noise". That SpecAn, display may have rather ugly spurs, but in applications where they matter, spurs can be filtered out.

@sbreheny 9 жыл бұрын

In addition to the loop filter components, the remaining issue could be related to power supply noise. 68kHz sounds like it could be from a switcher or from the display. Often the power supply quality and the bypass cap selection and placement are supercritical for synthesizer ICs.

Well they are half way there then. I suspect the best thing for rigol to do is release another update that includes a menu item somewhere with a list of varying tweaks, that should encompass the tolerances of the filter parts, across the affected scopes. Thumbs up to rigol though. I wouldn't like to see a major recall to repair them, as the profit margin is so slim, it may make them think twice about making and releasing affordable scopes in the future, as one bullsup and there goes what little profit there was in it.

For me, i can see here a good example of "not-so-well" engineering/designing process and without any further inspection of the PLL behavior and/or output probing at all. I think, they probably went like: hey it´s running so up to the next....If they had have a look at this, they had noticed that by the very first probe;) RF-Suff is not that easy, as all traces act like an antenna in these high frequency range if they are not of a specific lenght with respect to the frequency used on them....always use a "smith-diagram" first, to see if your trace is acting like an antenna...after that is done you know if they do need termination, or just nothing due to correct trace lenght. As if they are not properly terminated they will result in a poor harmonic damping, or even amplify them, if you have it all goofed up....

I received my new ds1054z this morning. It has the updated software installed, which is good. I'm a touch unsure whether the board has been updated though, the first time I started it up it reported board version 0.1.1, I checked this video to see if that's the version of the board on your scope (it is). But then I turned my Rigol on again to double check, and it states version 0.2.2. Rebooted, and 0.1.1, reboot, then 0.2.2, reboot then 0.2.2 again - It looked like it was going to alternate for a while there. So I'm not sure if the board has been updated or not, but it looks like there may be a bug reporting the board version number.

@nsjohnston 9 жыл бұрын

It seems to be reporting version 0.1.1 consistently now. I have unlocked all the features on it, so maybe that has cleared up whatever was causing it to report the board version as 0.2.2.

Well its actually firmware, they are changing the pll setting registers, so, you can think they are actually changing the way this piece of HW is behaving, many reg are like programmable resistors, capacitors, dividers .. etc etc .etc, they are changing registers / setting on a chip that is built into this HW. since the host processor init this PLL at the start (I assume), you can change the FW of the host processor to do a different thing at the start with this PLL chip. This not solved in SW domain, but tweaking the HW, programmable HW.

@teardowndan5364 9 жыл бұрын

In modern hardware, tons of parameters are programmable even when the component itself does not run code. If you take a tablet or phone for example: the flash memory, SoC, power management IC, broadband chips, touch-screen controller, display controller, backlight controller, etc. all have countless registers or even embedded microcontrollers allowing programmers and hardware designers to tweak their behavior by software/I2C/SPI/whatever. As long as there are no fatal physical design flaws like wrong pinout, excessive power supply ripple, grossly incorrect component values in analog circuitry, etc., many defects can be addressed by software. In Rigol's case here, the question is whether those PLL register tweaks will help the vast majority of people across all possible component tolerance variances out there. The line between software and hardware in modern hardware is blurry since so much of the hardware's behavior depends on programming bits by software.

@JamesReedy 9 жыл бұрын

I'm with Dave, they probably bodged the PLL loop filter values or got the wrong parts in there somehow and are doing a decent job of masking the error by fiddling with the PLL setup register values. As long as it's a stable fix, it's a stable fix. Hopefully if it is the wrong values it's consistent across a given SN range and will patch them all up accordingly. That said the issue is showing up to varied degrees from one example to the next in terms of peak to peak jitter. That could be component tolerance within the nominal range of the incorrect parts, it could be an indicator of just how unstable of a condition the PLL is operating in or it could be the right parts and the wrong register values. However as Dave pointed out, that clock looks like hammered dog doo doo. ADI has some really decent clocking solutions, I don't think a properly setup ADI PLL is going to have that awful a jitter spectrum.

At 21:08 Dave goes on to say the clock's hardware is creating too much jitter so this video is showing a hardware problem being fixed using software, not the ideal solution but a realistic one due to the expense of a recall. The problem with these lower cost electronics is any hardware problem like a failed chip requires an end user to replace the entire unit all too often when just out of warranty. Here is an example where the next model up is a better and safer buy IMO.
