content: Hey, I'm new here but just wanted to check if anyone else has encountered these RIGOL (maybe) scopes that have the product number DS1102Z-EThey're implied to be part of the 1000-Z series like the popular DS1054Z. I only saw them today and were all in either sites like aliexpress or banggood. I did find a (supposedly) Chinese RIGOL site where the product is featured and also found a Chinese shopping site where the Oscilloscope is sold and even has reviews.It's supposedly a 100MHz, 2-channel scope, a sort-of successor to the DS1102E.Obviously, I went into this more than a little skeptical but I wanted to ask if any of you that have more experience with these can verify if these are a real RIGOL product that is specific to China or is a very elaborate way of fake oscilloscopes. The site looks quite real but I could be wrong. There are legitimate RIGOL products there too. If this is real, it's quite competitively priced (even cheaper than the DS1054Z).The Chinese Rigol Site (?):https://www.rigol.com/news/news/48.htmlThe Shopping site:https://item.m.jd.com/product/100011860852.html?pc_source=pc_productDetail_100011860852AlieExpress:https://www.aliexpress.com/item/10000216624210.html?aff_platform=aaf&sk=AYNZbMb&aff_trace_key=104f80654a454cdea8720cb0fa55a40a-1589370486926-06086-AYNZbMb&dp=haj.camillesonthehill.co&terminal_id=9f29c431489747b397f78e4791920d19&tmLog=new_Detail&aff_request_id=104f80654a454cdea8720cb0fa55a40a-1589370486926-06086-AYNZbMb

content: Quote from: maseryoda394 on August 25, 2020, 07:37:35 amIt doesn't look like it's available outside China yet.It's 99.9% likely to be hackable but I can't tell you if it's as simple as using Riglol.Note: If you're not using BNC cables and direct connection to the 'scope then the extra 100Mhz won't be very helpful anyway, it will mostly expose the limitations of non-active oscilloscope probes. Maybe better to use the 100Mhz low-pass filter.(in exactly the same way that using 1x probeswithoutthe 20Mhz low-pass filter is foolish).Bottom line: For 260 Euros? Get one anyway!

content: Thank you for your reply .I already got it, it comes also with all the options unlocked and 150 MHz probes, and I only paid 215 € not even 250.I just wondered if it's hackable. to be fair 100MHz is more than enough for my current application of measuring DC TO DC converter ripple and eliminating it using the capacitance multiplier as shown in Dave's video.Thanks again.

content: Quote from: S. Petrukhin on November 06, 2020, 12:31:22 amSure, but that's not just a Rigol problem. People do that to lots of 'scopes.Another trick is to replace the knob with a bigger one, it gives better control and doesn't break the "warranty void" sticker.The GW-Instek 'scopes have a separate button to avoid menu mis-selections.I just bought a 'scope thatdoesn'tdo everything through a stupid twisty knob and it's awesome.

People moan about the vertical position response on Rigols (although I neveroncefelt it prevented me from doing my work) but even if they fix that you'll still be using a horrible twisty knob to navigate the menus.I expect that touch screens will be standard within a couple of years, even in low-end 'scopes.

It seems more likely the DS1102Z-E is a stripped down version of the DS1104Z than a stripped down version of a 200MHz capable scope.

content: As I noted the DS1102Z-e being available on german amazon, I wondered if anyone could share some experience in daily handling.My use would be a beginner to a DSO to get additional coverage of routine measurements, like jitter on some USB Power supplies etc. - and on my bucket list for the future I still have the item: Measurement of the burning time of a photographic flash by converting the light with a photodiode and measure that with an oscilloscope...(Flash duration is about between 1/10000 sec and 1/100 sec for slower studio flashheads, meaning some duration betwwen 10 ms and 0,1ms)For the price of about 260 € for Prime members including shipping, I cannot complain, and if I really would feel the need for a better scope, I would know what I have to buy and won't have much loss of value by selling it after a short time...Opinions?

content: Only make sure you never accidentally activate AC mode on that channel. The probe utilizes the 1MOhm input resistance of the scope as part of the voltage divider. If this is galvanically isolated by a capacitor, application of a high DC voltage will completely drop across the scope's DC block capacitor which may break down (actually, probably something much less troublesome will happen -- the COSMO semiconductor relay that's intalled to bypass the capacitor will zener break down and limit the voltage across the cap, most likely without any damage). But in general, this may lead to a potentially dangerous situation, especially if the DC block bypass is arranged as an electromechanical relay or a plain old switch in the particular scope in use...

I contacted Rigol, 1 year ago (October 2021) and they told me that it is a software problem...I received my scope in September 2021 with firmware version 00.06.02.The brightness problem with the 5ns timebase already existed with this version.Updating with firmware V00.06.03 did not solve the problem.Version 00.06.02 dates from October 2019, information written in the Release Notes.So the problem exists since this version and maybe even since the conception of this scope.At least 3 years after V00.06.02, Rigol still hasn't solved the problem and some people on the forum (maybe working at Rigol company) say it's a software problem!!! Easy to keep users waiting forever.But why the defect has still not been resolved for so long:First possibility: Rigol is a small company with few incompetent developers and they don't have time to solve a 3 years old bug?Second possibility: the problem is hardware with board version 0.0.1. It cannot be solved without a hardware upgrade!Regards

content: The problem is clearly visible at maximum vertical sensitivity (starting from 5mV/div.). When the second channel is turned on, both beams move upwards. To return the beams to "Zero", you need to switch both channels to the "Ground" mode and back, then both beams are combined into one "zero" line. Many people have this problem, maybe you are lucky.Yes, and at the same time, a relay clicks on the second channel. There is one more point: when the second channel is turned off, the voltmeter readings are absent, and in the first channel, when it is turned off, they remain the same as they were before the turn off.

If I get any information about this bug, I'll let you know.

I have not found similar models, which suit me, in the Rigol range.These 2 models are more expensive than the Rigol.But Santa Claus is coming soon, I am thinking.rsjsouza:The flickering/flickering of the traces was, according to Rigol, an electronic failure.Fortunately, this failure does not occur on the entire DS1x02Z-E range.I had no luck with this failure but what prompted me to return my oscilloscope was the loss of luminosity with the time base at 5ns.I still think that the DS1x02Z-E range is a good entry level at a very correct price, content of the possibilities of this device and that it is suitable for many users. Unfortunately for the use that I have, this defect is very annoying for me.

content: Hello tmntr,It's been 3 weeks since I received my Siglent SDS1204X-E to replace the DS1102Z-E that I sent back to Rigol.I bought it from an authorized Siglent dealer not far from my home, unlike the Rigol which came from Germany. This proximity seems important to me following my bad experience with the DS1102Z-E.It is difficult to compare these 2 scopes, 4 channels against 2, 200MHz against 100, and other functions that do not exist on the Rigol (hence the significant price difference).With the Siglent, there is no loss of luminosity, even during the displacement of the traces on the screen and even with the time base at 5ns unlike the Rigol. This is normal operation.The action on the buttons and encoders is immediate. The Siglent encoders have a normal sensitivity unlike those of the Rigol and mainly the one that adjusts the brightness of the screen on the Rigol. Since the years that this scope exists, Rigol could have improved it even if some defects can never be solved.Having used a digital Tektro for many years, the faults of the Rigol DS1102Z-E bothered me a lot.The Siglent has an integrated http server which allows it to be controlled and to export the traces. It saved me from developing software in C# as I had been able to do for my Rigol and my Tektro.I recognize that this Rigol DS1102Z-E has an interesting performance/price ratio and should be suitable for many amateurs who are not too demanding.So why this Siglent? How can you be sure that it corresponds to what is expected of this device?The best is to know a user to have his objective opinion. And in case of acquisition, to have a period (normally 15 days) to try it and in case of dissatisfaction to send it back and get a refund.In short, I am delighted with the purchase of this SIglent SDS1204X-E scope, I do not regret this change of oscilloscope, even with a price difference of almost 3 times.

content: Or probably just to solve the hardware defects of this scope.The loss of brightness and other problems reported in this forum by users are not software problems as Rigol and others have told me.This scope was put on the market in 2019 (date of the first version of the software) and even with the different versions of the software the defects were not solved.If for 4 years, the engineers have not solved the problem, is that they are bad? No, because producing scopes with a BW of several GHz is not easy. And if it's not a software problem, it's a hardware problem.Knowing the difference between hardware version 0.0.1 and 0.0.13 also seems interesting for users future buyers.

content: Just when new firmware comes out, they have a description of what has been changed or fixed. But there is no information anywhere about what has been improved or fixed in the latest (possibly the latest) hardware version.On the one hand, if a manufacturer makes changes to its product and this is not a correction of an old error in the board layout, but an upgrade, then this is understandable, but when three years have passed since the launch of this sight on the market and when you buy a device, you get the first version of hardware with a possible flaw in the circuit, it becomes a little unpleasant)

content: trmntr is right, a factory reset might solve your problem.On the Rigol, which I had, it was impossible to reinstall the latest version of the software after trying older versions.At each attempt to reinstall the latest software version, the scope displayed "Update was failure".To perform a hard reset, I had received from Rigol the following procedure and it worked, the latest software version could be reinstalled:"Put latest firmware on to the root directory of a jump drive formatted to FAT32. The newest firmware can be downloaded fromhttps://www.rigolna.com/firmware/.While the device is off, insert the drive into the USB port in the front. Start repeatedly mashing the "Help" button and power up the unit while continuing to press the button repeatedly. This should cause the device to try to boot from the external drive with the new firmware. If the firmware is loaded successfully, the instrument should not boot into the red screen error, but it will remain unresponsive while the firmware is installed - this can take up to a few minutes."At the end of this long procedure, the messages displayed are in Chinese languages but the button to change languages automatically appears on the right of the screen. It's good.

content: Hi!I found one bug in the operation of the oscilloscope and I would like you to check it for yourself in order to understand it only for me or for all Rigol of this series ...Turn on the device, turn on one or two channels. On the left side of the menu, select measurements for the channel, for example, Vpp. In the Measure menu where Font size choose Large or Extra Large. Go back a little now to Statistic and slowly toggle this between ON and OFF. In this case, the selected Vpp parameter will switch to the extended window and back. At some point (no more than a minute), the device freezes, stops responding to the buttons. Beam settings can still be changed with encoders, but no correct parameters are displayed on the screen.https://www.bilibili.com/video/BV1KM4y167vVhttps://youtu.be/G7CreVuakn0

I notified that if I set the trigger to auto and the memory depth is set at 600k or below, then if triggering to the LM555 output on pin 3 (the LM555 is from the attached schematic) the waveform doesn't stabilize. But if changing the trigger to normal or set the memory depth above 600k then the waveform is stabilized. Is this normal ?If I trigger on the calibration signal with the initial DSO settings (600k memory depth and auto trigger) then the waveform looks good.
