content: The new Keysight/Agilent 3000T Oscilloscope is released today, and Dave has a world first review of it.It's a replacement for the existing 3000A X-Series, and is essentially the same in many ways, so only the differences arecovered in this video.A lot of features from the 4000 X-Series have filtered down, and some things are now standard.How does it compare to the Tektronix MDO3000?Original 3000A review here:4000 X-Series review is here:

There is no reason not to add faster components even if they will just be used to boot the system and run the UI when they want an astronomically high price of $13,000+ for their scope.For that price, it should be performing additional functions like virtualized hosting + a SAN

content: I'm intrigued by the touch interface. When I use my non-touch scope, I'm constantly looking back and forth between the screen and the keys/buttons section. Using touch appears to be a lot faster and intuitive. For those who have experience with these scopes, I wonder what percentage of time they use the touch interface vs the keys/buttons?

content: Quote from: Tek_TDS220 on January 08, 2015, 02:45:57 pmFew words from my experience with scopes at work:Tek TDS 3000 Series: 70% Blind operation of knobs. After few years daily use of always the same few functions it's like 10 finger typing.Tek MSO 5000 Series: Although this scope sits most times in the cabinet it requires oftenly switching views from display to knobs. It's all a matter of habit. This scope comes with resistive 10 inch 4:3 touchscreen, stylus included. Compared to the finger friendly UI from the DSOX3000T Series fromHPAgilentKeysight the Tek MSO is quite difficult to use without stylus in menus.Tek TDS 460A: Seldom use, although it's placed next to me at my work bench. But feels like TDS 3000.R&S RTM 2000 series: I feel like an idiot that can't even ride a bicycle. It's quite far away from my Tektronix habits.

content: Quote from: Razor512 on January 08, 2015, 02:26:05 pmAdding a 'Core i7 4790K' would achieve precisely nothing, because the Infiniivision X-series scopes don't use Intel processors. Nor do they run any flavour of desktop Windows. Windows Embedded Compact (formerly CE) is a totally different operating system.

I'm surprised Keysight didn't get called out on such an obvious marketing wank...And when we're on the topic of bandwidth: why not a comparison of a 1GHz signal being measured with the MDO3000 and the 3000T usingthe supplied probes? The Tek comes with 1GHz probes compared to the 500MHz ones Keysight provides. What difference does this make in practice? Surely a topic worth investigating!

After all, that was the whole intention of these scopes from the get-go - build in the hardware and then enable once market pressures force you to.

content: Quote from: jpb on January 08, 2015, 10:07:12 pmAs you say, same thing happened 15 years ago. The sad thing is that HP became run by money men and women who had no idea how to run a business consistently, always looking for short term monthly and quarterly gains, they thought that being an accountant or a "banker" was enough without having to have a clue about the business.The HP brand today is junk, particularly after their EDS takeover and more recently the pissing contest with Autonomy, it's become a race to the bottom. This is quite unlike Agilent who managed to maintain their reputation, as I hope Keysight will.I am no fan of rebranding, and find the continual supposed added value from the branding, M&A and strategy MBA wankers to be nothing short of money for old rope in almost all circumstances. I am sure I'll still be referring to Keysight and Agilent as HP for many years yet, keeping the memory of the good years, when reputation was everything, and the bean counters and bankers remained behind their desks and steered clear of the boardroom.

content: I wonder if there will be any more firmware updates for the 3000x now that is in out. As for the cost being the same as the 3000x, yes it is currently the same but I think they just bumped the price of the 3000x. Net result, (if I am correct) is that it is more expensive than the 3000x of a few days ago.

The 'ultimate scope' upgrade was a great offer, but now (I presume) they're back to charging hundreds of $$$ for each and every serial protocol decoder, the whole range just became much worse value

They have a new product that they think trumps the competition so they think they can charge a motza for it.The MDO3000 though is a real threat with their now free spectrum analyser. I haven't look at Rigol's or others in that price range, but it's probably a battle of those big two.

content: My guess re "Keysight" is that a fair bit of their PROFIT comes from Military/Defence sales; the low to mid price section of the market I suspect has very little profit margin.To me the name 'smells' of a marketing study merging Key as in security and Sight as in the sense of either predicting or gunsight both with strong military type associations.The touch screen looks nice but I won't be looking to upgrade my DSO3054 until they have an order or two more memory points, being able to look in detail at both mS and nS timescales from the same triggered event would be handy. The MTBF figure is a little reassuring as I presume a lot of hardware is common with the 'old' 3000 series.

content: All the way back on p30 of the 37 page (!) data sheet, it notes the 8" screen has a resolution of 800 x 480.They also continue to benchmark against similarly-priced Tek, when I suspect their real competition is much less expensive Chinese brands.My guess is keysight will gradually lean towards high-end stuff. As US .mil spending wanes, and Chinese .mil expands, they may lose that too.Still stumped that Keysight doesn't do just the box, and couple it to a tablet with a decent display, a la Samsung Galaxy Note 12.2

content: Now what would be interesting would be an "Acquisition Box" and then a separate "Remove display AND physical button/knob front panel". So pretty much take the front panel off the scope and let you carry it around leaving the acquisition hardware on the bench. That would be pretty cool.That could be third party hardware too. Just make an API for the actions and anyone can make a rotary encoder knob board.

content: It's crazy to pay $5k and up for low-res touchscreen instruments. Particularly when iPad/Galaxy displays are amortized over millions of units. Make the acq box look like the bottom and right hwlf of the scope, and cradle a world-class touch display in the upper left quadrant. I love the XGA in my 7000 series Agilent, and would never downsize nor down-res.They are making apps to control the scopes from tablets anyway.Enough room on my 12.2 Galaxy to display both high res scope and plenty of other stuff (34461a/SDM3055 multimeter charts/5162 AWG display). Not to mention connectivity etc built in.While Tek and Keysight play Chevy and Ford, the Toyotas and Hondas (think 70's, when their qualities were still hit and miss) are gobbling up the low end, with sights on moving up. History does have that habit of repeating.

Maybe it's time to work on that. Easy enough to boxcar/rolling avg to get into 12-bit territory. These displays can't even do 10-bit.Help us old guys with bad eyes out. BIG screens with Lots of resolution.ETA: Same goes for DMM/AWG/ SA and so on. EVERY instrument over $500 should have the ability to use a bigger display. DVI/HDMI/WiFi or BT to a tablet, etc. Stop making us squint!!!

content: Big screens are a delight to work with. I had a 17" display driven from an Agilent 80something (1GHz Infiniium) on a repositionable arm and it made poking around circuits so much easier. I could probe and glance at the display without moving my head, critical when trying to keep probes on eeentsy tiny components. Not only that, other engineers or techs can see waveforms without crouching over the person doing the work. Try it! It is liberating!

content: Bringing the advanced maths and segmented memory as standard is nice, they were features hard to convince people of the value of but are a pleasure to use.The front end boards are still stratified into 100-200MHz, 350-500MHz, and 1000MHz variants so the slightly increased sample rate probably isn't much of a change.

It is a bloody toy for a bloody rich kid who wants flashy colors and two strippers on some shiny pole, and that isn't with all the functionality included even. You have to pay for the extras. Bloody yarn balls, they keep low balling suckers in the nut sack!!!! and they ask for more?I don't know about you guys,but I think I can look up some hardware for the same specs with lower price tag and it doesn't have to be from the mainland either.

content: The starting price for the 3000T series in Germany is Euro 2700 for the two channel version and I think this is a reasonable price for a professional scope.http://www.datatec.de/Oszilloskope-Probes/Oszilloskope-Keysight/Keysight-InfiniiVision-Oszilloskope/Keysight-3000T-Oszilloskop-Serie/index.htm

content: MSOX3024T with all licenses ~13K Euro. Better try to get a used 4 channel MSOX3024A with all licenses for a third of the the price.I admit, I had my prejudices with the touch screen. During Daves video I thought sometimes "nah - don't need it" and sometimes I though "well, quicker as with the regular knobs and buttons".But then - at the end of the video (at 35:30) - Dave reaffirmed my prejudices by showing the screen of the scope(see screenshot attached) and now I know: no, I DO NOT WANT a smeared and smudgy screen covered with fingerprints and dirt.I know enough people who do not care - many seem to even never clean their glasses. Brrrrr. But I do care - I want a clean screen. My mobile phone can be cleaned quickly by wiping it at my shirt or trousers, the scope will need a dedicated peace of cloth laying around and will need some time to be cleaned.But in a few years, when they finally invented grease repellent screens, I probably will be interested....

content: I can stream 4K HD video from YouTube, I can't imagine video over ethernet would tax modern technology that much, even with a requirement for low latency. Even simple RLL compression would massively reduce scope display bandwidth.Whilst I totally agree that "retina" type resolution would be a waste on low resolution applications like 8-bit oscilloscopes, I do think that they provide the potential for a clearer and more usable graphical interface. Applications such as frequency domain analysis and data logging trend trackers can also benefit from the resolution.

content: Quote from: HighVoltage on January 10, 2015, 09:25:23 amwe have a MSO-x 4000 And the screen is a joy to work with. bigger screen means you see more from the data.Quote from: Pinkus on January 10, 2015, 03:06:05 pmAs a user of a 4000 with touchscreen i can say that with normal analog work I don't use it a lot. with the wave-gen I don't use anything else. I believe it is possible to do it with the knobs. also when using serial decoding and measurements functions I use it sometimes. And if it is on you don't see the fingerprint as much.

content: Quote from: EEVblog on January 08, 2015, 09:40:03 pmActually I was just joking, but your response is ridiculous. I haven't seen any explanation why the review wasn't released on this channel. All I know is you released it on the 'supported' channel and that there is a jitter issue. When are you going to release the review on this channel?

content: Quote from: Fungus on January 08, 2015, 01:15:07 pmDave said it will be the same price as the older MSOX3000A modelQuote from: mfeinstein on January 08, 2015, 05:51:39 pmA few but not worth it IMHO. Smart probes, bandwidth, touch screen, better fft features and a few options already included.Keysight took their sweet time engineering the MegaZoom. It was superior to anything else on the market. Now that competitors catch up, Keysight is unlocking features and making easy one-ups because they have reserves. But, I guarantee that after there is a clearly better scope from Rigol or Techtronix, Agilent will release the next generation ASIC and scopes based on it. They are just adding wank as long as they. I'd wait for the real deal - they're just milking the cash cow with no real effort as anyone would.Pity they had to change the main board and the FPGA, if they had just wacked on the touch screen, it would have been a really easy hack. But still there is room for both soft and hardware hacking.I hope they'll upgrade the DSO2000A soon. I'd like to see serial decoding on the logic channels. That's the greatest shortcoming of the 2000

content: I am very surprised at the 250kh MTBF, I would have thought that the electrolytic caps. in the PSU would fail well before that.

content: MTBF of 250khrs does NOT mean that the scope should last for an average of 250khrs.The actual probability that any one particular scope will survive to its claimed MTBF is merely 36.8% (e^-1). in other words, 63% will fail by those 250khrs. MTBF calculations do not apply when wearout, whether caps in psu, encoders and whatnot, is involved.
