Hello from Romania Dave! Long time follower here. ( : Thank you for the awesome content! and the 'Made in Romania' shout-out, and also thank Rohde & Schwarz : )
Siglent and Rigol make some good stuff for the price. I think Siglent is good. I have the SDS 1104X-e and I still think it's the best bang for the buck scope anywhere. I doubled the bandwidth with a hack posted on the EEVBlog forum making it as good as the 1204X-e. It's not "great" at anything but good for everything if you know what I mean.
In my first proper engineerig job there was plenty of excess equipment after the firm downsized. the front covers were great when the scopes were in storage. No risk of damaging the screens.
The logic analyzer HDMI connector is a Type B "dual link" HDMI connector. It is the HDMI equivalent of dual-link DVI, though it was never used in any products.
If you use the front cover as intended, you aren't using the scope or whatever for its intended use, best use for the cover is as a tray for drinks etc.
I got see this scope back in August of last year and was so excited to see it hit the market. This is a really amazing instrument, and I'm so glad that you were able to review it :)
Guaranteed there are at least 15 R&S UI designers and firmware designers listening to every word from Dave, and there will be a few firmware updates out soon for this, "Dave Fixes" as updates.
@@EEVblog Absolutely, you are the best test engineer around, looking for all the edge cases, and even if half of them are only a "funny that" you do get a lot of those test cases, as you do the things most users will do, just a lot faster. Just be thankful nobody has yet sent you a Therac25, that bug was a doozy....
50:00 I’ve been evaluating the MXO4 in my lab, and what the single event color palette does is to basically nearly invert the intensities, so it reduces the intensity of frequent events and increased the very rare ones so they stand out.
I rather like face plates like that. We've had a few devices do the old rapid & unscheduled self-disassembly stunt a few times and it's nice to have faceplates on equipment not in active use just in case.
2:00 Yes I am a front cover fanboy. I had one fabricated in aluminum to protect my Phillips oscilloscope in transit. Its plastic cover shattered, protected the scope but revealed a need for a stronger cover. If you never take the scope anywhere it probably is not useful or necessary.
The front cover piece made me laugh. I don't have the patience or organisation to take a cover off and on before and after use. RIP Hameg. My first scope in college was a 15MHz? HAMEG 205 CRT scope. I ate only baked beans for a month to be able to afford that sucker.
700MHz passive probe, or really "there probably is a signal there" probe, at 700MHz you better only be probing the output of a TV transmitter at 100W power output, to hope to get a decent signal without too much loading., 100R at 700MHz, really going to load things down.
What's odd is when you added peak to peak for a second time at ~27:00 it showed you a duplicate measurement instead of recognizing that it was already there. Basic bug that they really should fix
Hi, firstly need to say that - a lot of inspiration from your videos and channels during last 7 years. Thanks for you job!!!!! Second one - WHEN You will get a R&S MXO5 ????
Wow thanks that was an awesome review very in-depth you cover a lot of key points definitely one to having a lab I was happy to hear you mentioned they have higher end stuff as well yes for those of us to get into specialized work but it is an amazing piece of technology hopefully there will be resolutions for those crashes it's the only thing that holds me back many times in considering software driven tools keep up the awesome work❤
@@youssef8955 Well then it is probably not true that you are "never going to get one". At the time I was a student, there was some quite unaffordable equipment that by now is in the dumpster of for which alternatives exist that cost $100.

Does it have "waterfall" display mode of the FFT? Or even an "SDR" mode? (FFT mode with a tunable small bandwitdh window that gets demodulated in narrow-band modes like AM, FM, SSB)
We can count our lucky stars that a lot of high-end scopes are used in environments where devices aren’t allowed to have internet access. Otherwise I think we’d already have everything subscription-based. I will say that I wouldn’t mind it if the manufacturers started offering software options as cheap, time-limited “rentals” instead of sales.

They already all support time-limited demo licenses, so this would be purely a marketing change.
A great device! But where is the 12-18 bit resolution??? You show a device that is advertised with it, but you don't check what resolution it really has... In the signal that was recorded at 46:42 in the range +-5V, one sees later in the enlargement a noise of approx. 10mVpp. This results in about 10 bit resolution. But the device was set to 18 bit! I.e. the noise should actually be smaller by a factor of 256.
R&S are not known to overhype their specs. In fact they are usually slightly conservative. So I doubt they would jeopardize their reputation by overhyping that.
@@lolilollolilol7773 At 55:50 Dave has shown the specs. For example, at 100 mV/div, a noise of 747 uV is given. A screen is 10 div high = 1 Vpp = 316 mVrms. 316 mV / 747 uV = 423. If I haven't miscalculated, that's less than 9 bits then....
@@Elektronik-1 There is a big difference between ADC resolution, effective number of bits and effective resolution. Your noise floor consists of many noise sources, ie quantization noise (ADC), thermal noise, jitter noise (clock). If your thermal noise would be down in the 14 bit region but you had a 12 bit ADC all you'd see would be quantization errors. It can be quite the advantage to have ADC noise magnitudes smaller than the thermal noise! Looking at most 8-bit scopes they as well have about 5-6 bits of effective resolution. Just compare some of those datasheets and look for the "RMS noise floor" As always, AD has a nice Appnote for that; search for "Understanding Noise, ENOB, and Effective Resolution in Analog-to-Digital Converters" (also, for the 10V/div range it's more like 10.8 bits of effective resolution :P )

And now go and compare this with other scopes that have 12 bit, 10 bit or 8 bit ADCs: ENOB is always 2-3 bits smaller than ADC resolution. Effective resolution is smaller as well, though not so much.
when I bought my old TEK it came with the cover. handy when I travel with it. agree with Sean BZA too. they are listening and waiting for you to find a bug in it.
New stuff , yep always. They will probably fix it and send an update out. As you mentioned this isn't a cheap machine to start with. I like it myself but no way i could afford one. 15 yr old Tek 3054B here.
How many MHz in a scope is necessary for which type of real world signals. Examples: Serial, I2C, MMC, Ethernet, PCIe, DDR5, 6GHz Wifi, high freq RF stuff. What signals are people actually measuring that they need $8000 scopes ? and how close can you come to being able to do stuff compared to the $1000 or $200 scope. ( Or if you did a video like this already, lmk! )
I have a 25k€ for WiFi application from R&S and I ordered this one for general purpose application. The needed bandwidth depends on you signal shape. For e.g. for square wave you need about 10 time the frequency of you signal to get a good representation.
Cardboard wouldn't provide nearly the same protection as foam, especially since it's meant to be reused. It's not eco-friendly-- it's a higher risk of shipping damage (much greater possible ecological impact) + cardboard has limited reuse
Channeling my inner Tron voice: "That is one big door screen." Regarding the front covers: Put me squarely in the "uses them as trays" camp. I think I only own 1 of them and it's lying on top of a box somewhere, helping a pile of random cables and other cruft balance precariously in a pile that's just awaiting a magnitude 0.0003 earthquake to tip over... an event which would necessitate me spending a whole 5 minutes cleaning and straightening to recover. But anyway....
What kind of scope would you recommend for a millwright? I don’t need anything super fast, in fact I’m looking for an hybrid between a graphing multimeter and an oscilloscope. Maybe an oscilloscope with super deep memory? But I need lots of channels I think. For checking things like quadrature encoders. And the other day I was troubleshooting a CNC lathe and the manual had a 12 channels timing diagram for the turret tool change sequence.
I'm forever spoiled by the Teledyne LeCroy WaveRunners we have at work for basic tasks... Would love to have one of these R&S at home, looks like a decent scope!😅
@@GeomancerHT He is definitely not being paid. And I'm not sure he gets to keep it, but I guess he does, given how much free promotion they get for free.
@@lolilollolilol7773 australia laws are very direct on this, it's called being paid in "species" not in cash, also if he is linking to the scope website and such, he is literally promoting it. Don't want to be hated by anyone so I will leave the subject, not my problem.
You have had the MXO4 for about 12 months now, Are you still happy with it? Did R&S fix the waveform update/s problem which occurs when you add a frequency measurement?
We do have the MXO4 and MXO5 in the lab for testing at my work. The scopes are superb, and the memory depth is insane compared to what we currently have. But that stops once you want to save a waveform to an external storage medium for further analysis or documentation purpose.. It's slow, like reeeeeaaallly slow, it took me more than one hour to save a waveform the same size as we do on our current 20 year old oscilloscopes in less than 2 min..... I know, it's unusual to need a signal over that long of a period (up to or more than 1s) but we do actually need to document / archive the whole length of the signal, customer request ... :/
Hi Dave, Just on that 700Mhz passive probe, Rigol has RP615A 1.5 GHz 500 Ohm passive probe, not sure if it is really possible to achieve this bandwidth on passive probes. These probes come as standard accessory with Rigol MSO8204A not sure if you have done review on that or could do one? Thanks
Is the R&S MXO 4 new? I'm just wondering since you compared to the Keysight MXO3000 series which is pretty dated by comparison. Even MegaZoom-IV is pretty old. And I believe Keysight has models with bigger screens like the 4000X and 6000X (although not much bigger). Still -- both are good scopes. I wouldn't complain about having either on my bench.
Yes, the MXO4 is quite new, but comparing it to the Keysight is still fair because Keysight hasn’t come out with anything new since then. They’ve just started updating the model numbers from -T to -G, the only difference being that the -G versions include most of the software options in the base price.
I wonder if they're doing an FFT for the frequency measurement and that's causing it to take a dump. The "fast" in FFT is relative.... Hmm.. the spectrum analyzer certainly is.
I think if you work with robotics and kinetic stuff there's always a chance some projectile that aimed itself at the eyeball misses the target and hits your prised 9G toy!!! so I guess in that case it might be helpful to cover the screen while you don't use Osci?
A would be unhappy with a scope having boot-up time like this one. Seriously, modern hardware and software tend to exhibit laggy behaviour as a normal and desired expirience.
The boot-up doesn’t bother me as much as the laggy UIs. Keysight is the only one to get this right at the moment. (And Rigol, who seem to copy Keysight, which here is a good thing.) The lower-end R&S models (RTB2 and RTM3) have atrociously laggy UIs, despite having very competent acquisition hardware. The latest Tek models are ok, but still have slowdowns at times. Same with LeCroy.
Scratch the surface Dave. I learn lots watching someone who knows what they are doing poke around a new scope. I point a browser at the RTB2004 then I can have as the screen as big as my biggest monitor. Awesome out the box feature (with nothing to install) and would make it easy to screen capture. I assume this has that.
Hello from Romania Dave! Long time follower here. ( : Thank you for the awesome content! and the 'Made in Romania' shout-out, and also thank Rohde & Schwarz : )

18:35 When you dragged the measurements around there was an option to dock them to the left side, presumably the same is also true for statistics tab.
Would I put the front cover on? I can assure you that if I had this scope, and I had paid for it myself, I would definitely put it on.
Agreed. I keep the cover on my scope when not in use because I paid mid 5 figures for it. It's definitely different when it is your money.

Yes, the MXO4 is quite new, but comparing it to the Keysight is still fair because Keysight hasn’t come out with anything new since then. They’ve just started updating the model numbers from -T to -G, the only difference being that the -G versions include most of the software options in the base price.
Wow! Thank you you this review. This is a great scope. I really love my RTB2004 But bigger is always better.
I do love the front cover for my HP 1740A, a scope you know too well,
I wonder if they're doing an FFT for the frequency measurement and that's causing it to take a dump. The "fast" in FFT is relative.... Hmm.. the spectrum analyzer certainly is.
Oh Dave what are you doing!? We don't turn it on; we take it apart. 😁
Next video probably.
What is the screen refresh rate? As the visual waveforms can only update as fast as that really.
It's the waveform update rate that matters. The collection of that data can be presented the screen slower.
17:29 the Greek letter σ is lowercase sigma
I use that front cover as a mobile tray at our lab
Nice jobby!
Eevblog, beautiful .
Those probes cost more than twice my entire scope and probes! 😅
More than 100s of my'ne!
A tad pricey.
I think if you work with robotics and kinetic stuff there's always a chance some projectile that aimed itself at the eyeball misses the target and hits your prised 9G toy!!! so I guess in that case it might be helpful to cover the screen while you don't use Osci?
A would be unhappy with a scope having boot-up time like this one. Seriously, modern hardware and software tend to exhibit laggy behaviour as a normal and desired expirience.
FFT functionality is impressing, btw
The boot-up doesn’t bother me as much as the laggy UIs. Keysight is the only one to get this right at the moment. (And Rigol, who seem to copy Keysight, which here is a good thing.) The lower-end R&S models (RTB2 and RTM3) have atrociously laggy UIs, despite having very competent acquisition hardware. The latest Tek models are ok, but still have slowdowns at times. Same with LeCroy.
Is there a giveaway? 😅
Scratch the surface Dave. I learn lots watching someone who knows what they are doing poke around a new scope. I point a browser at the RTB2004 then I can have as the screen as big as my biggest monitor. Awesome out the box feature (with nothing to install) and would make it easy to screen capture. I assume this has that.
Yes, the MXO4 supports remote control via a browser (nothing to install)
So where'd the comments correctly pointing out that this should be clearly labeled as sponsored content all vanish to?
Every scope should have a front cover, as should other cool instruments too 🙂
She's a beauty! Though I think I'll stick with a used CRO on eBay and put the savings into a new car (and maybe a downpayment on a house)!
@EEVblog - Dave: send old scope to us less fortunate. i'll buy 200 tickets in the lottery
If you get bored with that 'scope, I'll pay for shipping to get it here to Colorado, USA. :)
If the Nx single feature becomes too much of a burden I can take it from your hands 😉.
You sir have obviously hacked the web cam in my shop since you know my nightly test equipment worship ritual.
And the 8K USD price is just for the small 200Mhz version - this is a 26.000USD version. Amazing unit! just can't get any better..
I'll wait till the Hantek version comes out. 🤣🤣🤣🤣
Will this oscilloscope be enough for an Arduino Uno??? /s
I like it I think I need it time to break out the check book lol.
There are companies that make Windows based scopes???
Yeah, lots of older high end scopes and other equipment like Spectrum Analyzers used Windows on them.
After seeing a mouse curser on the screen, i want to see it play doom
