Decades ago there was a huge push to green up cities by planting trees everywhere possible. A couple of decades after that there was a huge push to remove trees because of infrastructure and safety concerns. Now a few decade later we are back to putting the trees back in. I'm always for more trees but hopefully this time it's a little more long term this time.
This is as good as when the engineer from the Claude team said they load their website in such a way as to protect against hostile actions such as scraping.
Gotta love how they moved the "Create Email/meeting" buttons in Outlook mobile and stuck the Copilot button there so that you will hit it accidentally.
It's an interesting case to me. The company I work for has been shipping systems on windows since the 90's despite pretty consistent requests from customers to ship hardware on Linux. 2 years ago we started creating our own Linux distribution and this year started shipping products on it. We still ship a lot of stuff on Windows 11, but that market share is starting to shift now. 10 years from now I could see us completely moved to our Linux distro. Now, what's actually interesting is that it wasn't customer requests or efficient capital allocation that drove this. Microsoft effectively forced us to do this against our will by a combination discontinued products and handling of Windows 11 and now that we've spent the capital we won't be going back.
You can't abandon Windows because of software X, Y, Z. Over the years vendors move to multiplatform as more and more customers ask for it. These changes are slow but steady. And one day you find out that the last "must have" software is not limited to Windows anymore. That's when the dam breaks.
If you are an absolute nutcase, you could characterize a set of line stretchers and a multiplexer on a high end VNA then offset the inputs of the 4 channels on that UXR with them, take a capture and finally rebuild a 1TSamp/s signal out of the 4 results.
You have to have the 240V model of the scope to run all four channels at full rate (110GHz) though.
The older Tektronix TDS540 series did this, but at much lower rates as was common in those days though. Internally there are differential feeds from the very beautiful hybrid ceramic input boards to 4 DACs, with some clever switching so that a single input can be sampled by all 4 DACs with a suitable offset to create 4x the sample rate when running with all 4 inputs.
The calibration procedure on the scope fiddles with the time alignment to get the different DACs correctly offset so that the combined signal is correct.
The hybrid ceramic input boards in their metal cases are a thing of beauty, fragile (don't ask how I know), but beautiful.
Yup, a lot of scopes actually did this internally and some still do. It's part of why some scopes lose half their BW when you go from 2 ports to 4 ports (some go the other direction and run multiple ports on one very fast ADC), they split the digitizers. It's just very very difficult to keep it working external to the box mainly because of line drift.
Keysight at least, has a fab where they make their own ADCs. Those are something like ENOB 6, 10 bit raw up to 120GHz and are used in their oscilloscopes but can also be purchased standalone.
Oscilloscopes also have a significant amount of additional front end conditioning, probe control, channel timing, and analysis software built into them. Most of the math functions on oscilloscopes use custom ASICs that work off the raw bits coming from the 120GHz digitizer which is non-trivial even just to receive. Calling it a plastic case around a digitizer is disingenuous.
It's technically not a signal generator but an Arbitrary Waveform Generator. It provides a base-band modulated signal to the signal generator which the sig gen upconverts to the RF carrier. If you purchased a Vector Signal Generator this would be built in but you can still buy them stand alone and they are pretty common. NI, R&S, Tek, and Keysight all have product lines of them.
Another way to think about it, this would be comparable to a signal generator in the same way that an oscilloscope is comparable to a spectrum analyzer.
What you call a signal generator is what most would call an RF signal generator. Both an AWG and an RF signal generator belong to the generic signal generator family. :-)
From the article
"I agree that a toxicological investigation of this anion would be useful now that we know its identity, but I am not overly worried about my tap water,” says Oliver Jones, Professor of Chemistry at RMIT. “The compound in question is not newly discovered, just newly defined. Its presence in some (not all) drinking waters has been known for over 30 years."
Chloramine has been in broad use for over a hundred years and this breakdown byproduct was well documented over 50 years ago and detectable in water over 30 years ago. What the article is claiming as new, or a "Phantom" is that someone imaged its particular molecular structure and is now requesting funding to run toxicology studies on it. There is no current reason to believe that it is harmful since tens of millions of exposures have not indicated any reactions to it over the past hundred years.

When you look at the state of health in the world nowadays I'd have to disagree: at least one of these "no harmful" substances that we ingest is killing us.
