content: Quote from: egonotto on September 16, 2025, 02:56:12 pmActually, these kinds of "teaser" campaigns often do attract significantly more attention (in a mathematically / statistically quantifiable way) than a simple "here it is" product launch.And, for better or for worse, it's become enough of an industry-wide expectation that if you just "drop" a product on the market, you often get the reaction "Whoa! Where did that come from?"

Or another favorite of theirs is "the most powerful ever."Feel free to add any of these:Revolutionary, visionary, intuitive, simple, seamless, powerful, extraordinary, beautiful, vibrant, and my favorite, magical.

"Stay tuned for a month we will show you something and then a blank picture.These teaser campaigns that your refering to' that should indicate that it attracts more attention.. aint those most directed at kids.. fx these pokemons, and all this other limited toys for childrenwith limited supplies.As far as I can tell it doesn't seem to resonate that positively - at least with adults, this speculative social media teaser-approach... Maybe its different with other segments fx for children or collectors and products with limited supplies...Most seem to prefer transparency & not vague baiting in a speculative attempt to create more obs.Article - New product preannouncement strategies (Keep it vague?)https://www.sciencedirect.com/science/article/abs/pii/S0969698921004136?The paper seems to conclude that "keeping it vague" was not positive for well-known brands with high brand familiarity, where transparency tends to be most favorable not least when it comes to cautious consumers,while for unknown brands, here could vagueness, hype & teasing on social media in some cases create curiosity.

I thought this forum's users are smart enough to figure this out without additional notices, perhaps I was wrong. And nobody cares if a specific person in that company was against it, at the end of the day the talk is cheap, so only actions matter. It's like with politicians - ignore what they say, but instead see what they do (or don't do).Besides, what I said is actually relevant as there is now a group of their potential/existing/past customers which would not do any (further) business with them due to company's earlier actions, no matter of they go on doing this teaser BS, or do a normal release.

Although I'm sure he can't do that publicly.I think the wording was not ideal.Now if you really want to get back at R&S for their firmware lockdown, figure out how to hack their licensing and publicize it.

content: I don't like being kept in suspense. But these teaser campaigns have at least the advantage that you can wait if you are close to pulling the trigger on a purchase.At work i sometimes get the info from distributors that it might be worth to wait because there is something new coming up. And it also happened that we got information about new testequipment early by signing a NDA.But private purchases for hobby are different of course. Would be a bit annoying to buy something and find out that 3wks later there is something much better for the similar price coming to the market.

content: Quote from: Sorama on September 18, 2025, 02:37:21 pmI'm really here as a hobbyist / ham radio operator (KO4LZ) who just happens to work for R&S - I'm definitely not here as any kind of "official representative"That said, I would like to think that I can add some value to the forum as a someone who has spent close to 30 years working for two of the biggest T&M companies, covering a very wide range of T&M instruments. In addition, I've made almost 300 videos for R&S (see link in tagline) and also produce whitepapers, webinars, etc.. So among other reasons, I use my "real name" to be upfront about who I am if I talk about R&S or suggest one of my videos in response to a questionAnd since I'm basically the apps engineer for the North American Product Management team, I try to help out folks here whenever I can, but I'm sure everyone will understand that there are things (a) that I can't publicly share and (b) that I don't know myselfI don't set our policies, roadmaps, etc. but I can pretty much guarantee that any feedback I get here does get passed on to the other members of my team, R&D, etc.As someone who worked face-to-face with customers for decades (and who was a T&M customer before that), I very much understand when people have issues, are frustrated / unhappy, etc. so I do try to use my position at R&S to help address any problems or requests that I get here.Hope that makes sense!

content: Yes, that's a bit disappointing. Nowadays, this is standard and doesn't need to be purchased separately.The Bode plot as an option is also annoying...Well, if the Bode plot can only be used with the optional AWG anyway, it doesn't matter, but then it should be sold with the AWG option, i.e., it should be included.Otherwise, it looks a bit greedy.The other options are “normal,” such as PA, LA, AWG, more memory, more bandwidth, special decoders... Other brands also charge extra for these.A quick comparison with the MXO4 reveals a smaller screen, less bandwidth, 1 channel instead of 2 channels AWG... There are sure to be more differences, and I'm curious to see how the price compares to the MXO4.In terms of bandwidth, maximum number of channels (eight), and display size, the SDS5000X HD could be considered in the same class.Its prices are known, so let's see how expensive the MXO3 turns out to be.

So every time you want to use the scope for something else, you need a trip to management, and have some goodwill and cost benefit analysis ready to make the scope do something. Annoying for everyone.R&S®MXO3-K510 is also priced at 2940 EUR (I understand it's free now). To decode UART.Vote with wallet I guess.I guess R&S doesn't understand yet, that the people in the Engineering department get roasted all the time if they want to buy something that management considers expensive. To the point where it's dangerous to your career to even suggest it.

content: Batronix has already listed them, including the promo.Just under €6,400 to get started, including VAT.Apart from the modest 100 MHz, that's not bad.https://www.batronix.com/versand/rohde-schwarz/MXO3.html

content: There are several new features related to the MXO series.- Waveform Histograms- K31, Power Analysis: 1. Efficiency, 2. Safe Operating Area (SOA)- K36, FRA: Reference waveforms on FRA curves- K510, Low Speed Serial Buses: Manchester triggering and decoding- Data and File Management: Histogram Data Export- Larger offset range at 1 MΩ between 60 mV/Div and 80 mV/Div and larger maximum offset than with the MXO5.I am curious to see if and when these improvements will also be implemented in the other MXO models.Best RegardsBernd

content: Quote from: 2N3055 on October 15, 2025, 02:21:18 pmYeah, it depends on the BWLook at given figures from HD-3 & MXO-3...So RF as ENOB & SFDR most of my interests is like to us it as a SPA with better performance as SD2K+ on 100MHz /10 bits using a custom differential probe.Also to like to increase the BW

content: Quote from: hpw on October 16, 2025, 05:27:30 amIndeed, the noise-floor is very dependent on the scope settings:For example, the noise of an R&S MXO4 is just ~10.3uV for 500uV, 1us, 2.5GSa/s, 25kpts, 50ohm, 20MHz, HD mode with 20MHz digital filter, while the official MXO4 datasheet spec is 20uV - probably R&S used longer time-base and higher bandwidth for the HD mode digital filter.It might be a good idea to check with scope owners what is the actual noise of the instruments you are considering for your particular use-case and scope settings...

content: Quote from: hpw on October 16, 2025, 05:27:30 amThank you for the tables, but I read them before. There is 2-3 times more RMS noise on MXO3 than on HD, with same BW.In fact, I have few scopes here that are better noise vise for about same margin.SFDR is also 14dB better on HD3....So like I said not close as you said.MXO3 has bigger screen and FFT is faster though.No scope will have full performance of SA for RF work. Spectral analysis on scope is useful in it's own right, but not full replacement for SA in RF. Specialized instruments always win for specialized work. Beauty of the scope is that it is a multitool.I can keep time domain window on, FFT and measurements on.I probe around the circuit and see all the signal parameters all the time.Frequency, period, duty cycle, DC Mean, P-P, RMS, AC RMS. On my scopes together with histograms and stats.And shape and spectrum.And if DC voltage looks suspicious, I break out "real" DMM that will show voltage to better accuracy and resolution for instance. Or frequency counter of a sort to better check a frequency. Or spectrum analyser to better analyse some "funny" peak that should not be there..

As calculation rounding will happen as more FFT length as like 32MSo floating point or integer usage will have different mantissas (integer or float using 16bit or 24bit or 32bit or 64 bit)Hp
