Rohde & Schwarz is set to revolutionize the field of signal and spectrum analysis with the launch of the FSWX signal and spectrum analyzer, an innovative instrument designed to overcome the limitations of current measurement methods.

Rohde & Schwarz introduced the brand-new FSWX signal and spectrum analyzer, the first multichannel signal and spectrum analyzer with multiple input ports, unlocking new possibilities in signal analysis. It is also the first instrument of its kind with a cutting-edge internal multi-path architecture enabling a novel cross-correlation feature. Combined with its low phase noise for high signal purity, its spurious-free dynamic range and its outstanding residual EVM, the FSWX delivers an RF performance like no other signal and spectrum analyzer in the market.

The instrument’s wide internal bandwidth of 8 GHz allows for comprehensive analysis even of complex waveforms and modulation schemes. Combined with a high measurement speed and analysis tools tailored to the user’s needs, the FSWX brings new levels of performance and precision to signal analysis for modern RF applications – from active RF components testing to state-of-the-art automotive radar testing to complex airborne radar scenarios and satellite test in A&D applications to the latest test challenges in WLAN and cellular technologies like 5G and beyond.

Michael Fischlein, Vice President Spectrum & Network Analyzers, EMC & Antenna Test at Rohde & Schwarz, is thrilled to introduce the new FSWX: “Our team has truly re-imagined signal and spectrum analysis technology with our new FSWX. They have come up with an innovative architecture and design to empower our customers to tackle complex measurement scenarios in the evolving landscape of wireless communications and radar technology that were previously unattainable. In other words, the FSWX makes measuring the impossible, possible.” The instrument’s innovative design features include multiple input ports, cross-correlation capabilities, advanced filter banks and broadband ADCs.

Multiple input ports

The multichannel FSWX offers the ability to measure multiple signal sources simultaneously, regardless of whether they operate at the same or different frequencies. With synchronous input ports, each featuring 4 GHz analysis bandwidth, users can seamlessly analyze the interactions between diverse signals. This opens up a multitude of new measurement scenarios, for instance, phase-coherent measurements of antenna arrays used in beamforming for wireless communications as well as in airborne and automotive radar sensors.

Multi-path architecture and cross-correlation

Its advanced internal multi-path architecture allows for the cross-correlation mode, a novel feature of the FSWX. A single signal input is internally split into two independent signal paths, each equipped with its own local oscillator and ADC. With this innovative design, advanced cross-correlation algorithms can be applied in the digital backend, effectively removing the inherent noise of the measurement instrument. This feature reveals spurs not easily seen without cross-correlation. It is especially helpful when, for instance, measuring Error Vector Magnitude (EVM), a critical factor in mobile communications. The added wideband noise of traditional signal and spectrum analyzers limits the accuracy and dynamic of EVM measurements. With the cross-correlation feature, however, the FSWX provides an unobstructed view of the DUT for precise EVM analysis.

The internal multi-path architecture also offers advanced triggering options. For example, users can apply an IF or RF power trigger at distinct frequencies, as the multi-path design allows for independent frequency settings for each receive path behind the splitter. This way, the FSWX can easily reveal effects between two RF signals.

Advanced filter banks and broadband ADCs

Traditionally, for preselection in the microwave range, spectrum analyzers rely on YIG filters. Since they are known for their challenging frequency response, YIG filters need to be bypassed for wideband signal analysis. The FSWX, however, employs broadband ADCs in conjunction with filter banks that span the entire operating frequency range, allowing for pre-selected signal analysis while eliminating the need for YIG filters. The filter banks provide high precision, optimizing instrument settings for specific applications and significantly reducing the risk of unwanted signal images contaminating results. For users requiring narrowband applications, a YIG filter can still be added optionally.

Innovative firmware applications

The FSWX also provides innovative firmware applications such as the CrossACT (Cross Application Control and Triggering) firmware feature. It synchronizes various measurements across different input channels, allowing for simultaneous analysis with multiple tools. This capability simplifies comparisons, such as determining whether the higher harmonics of a radar signal directly impact the EVM performance of a 5G signal.

The Linux-based operating system of the FSWX provides a high level of security and long-term support, essential features for users in security-sensitive environments. This robust operating system ensures reliability and stability, making the FSWX an ideal choice for demanding applications.

Have you ever heard the idiom “ripping off the band-aid? With thanks to Wiktionary for the definition, it means:

To perform a painful or unpleasant but necessary action quickly so as to minimize the pain or fear associated with it.

That’s not what Apple’s doing right now with the end stages of its Intel-to-Apple Silicon transition, which kicked off five years ago (fifteen years, ironically, after its previous announced transition to x86 CPUs, two decades ago). And although I’m (mostly) grateful for it on a personal level, I’m also annoyed by what’s seemingly the company’s latest (but definitely not the first, and probably also not the last) example of “obsolescence by (software, in this case) design”.

Nearing the end of the line for Intel

Upcoming MacOS “Tahoe” 26, publicly unveiled at this week’s Worldwide Developer Conference (WWDC) and scheduled for a “gold” release later this year (September or October, judging from recent history), still supports legacy Intel-based systems, but only four model/variant combos. That’s right; four (and in those few cases still absent any Apple Intelligence AI capabilities):

• MacBook Pro (16-inch, 2019)
• MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)
• iMac (27-inch, 2020)
• Mac Pro (2019)

My wife owns the first one on the list, courtesy of a Christmas present from yours truly last year. I’m typing these words on the second one. The other two are the “end of the line” models of the Intel-based iMac and Mac Pro series, both of which subsequently also switched to Apple Silicon-based varieties. Not included, long-time readers may have already noticed, is my storage capacity-constrained 2018 Mac mini; its M2 Pro successor is already sitting on a shelf downstairs in storage, awaiting its turn in the spotlight (that said, I’ll probably cling to my 2018 model longer than I should in conjunction with OpenCore Legacy Patcher, even if only motivated by hacker curiosity and because I’m so fond of the no-longer-offered Space Gray color scheme…).

But let’s go back to the second (also my) system in the previous bullet list. Did it also seem strange to you that Apple specifically referenced the model with “Four Thunderbolt 3 ports”? That’s because Apple also sold a 2020 model year variant with two Thunderbolt 3 ports. If you compare the specs of the two options, you’ll see that there’s at least some tech rationalization for the supported-or-not differentiation; the two-port model is based on a 8th-generation “Coffee Lake” Intel Core i5 8257U SoC, while my four-port model totes a 10th-generation “Ice Lake” Core i5 1038NG7. That said, they both support the same foundation x86 instruction set, right? And the integrated graphics is Intel Iris Plus in generation for both, too. So…

A one-year delay in sentencing for (some of) the Dipert family system stable aside, the endgame verdict for Intel on Apple is now coming into clear view. Apple confirmed that “Tahoe” is x86’s last hurrah; MacOS will be Arm-only beginning with next year’s (2026) spin. The subsequent 2028 edition will also drop Rosetta 2 dynamic software-translation support, so any x86-only coded apps will no longer run. And given these moves, along with Apple’s longstanding tradition of supporting not only the current but also prior two major O/S generations, it would make no sense for any developer to bother continuing to make and support “Universal” versions of apps (dual-coded for both x86 and Arm) once “Tahoe” drops off the support list in 2028…if they even wait that long, that is, considering that the predominant percentage of legacy Intel systems will be incapable of running a supported MacOS variant way before then. This forecast echoes what played out last time, when PowerPC was phased out in favor of x86.

which Apple itself condensed down to a 2 minute summary (draw your own “sizzle vs steak” conclusions per my recent comments on Microsoft and Google’s full and abridged equivalents):

involves the Liquid Glass UI revamp which, after conceptually originating with the two-years-back Vision Pro headset, now spans the broader product line. Translucency, rounded corners and expanded color vibrancy are its hallmarks; Apple even did a standalone video on it:

It looks…OK, I guess. On the Vision Pro, the translucency makes total sense, because UI elements need to be not only spatially arranged with respect to each other but also in front of the real-life scene behind them (and in front of the user), reproduced for the eyes by front-facing cameras and embedded micro-OLEDs. But for phones, tablets, watches, and the like…again, it’s OK, I guess. I’m not trying to minimize the value of periodic visual-experience refreshes, mind you; it’s the same underlying motivation behind re-painting houses and the rooms inside them. It just feels not only derivative, given the Vision Pro heritage, but also reactionary, considering that Google announced its own UI refresh less than a month ago (Android 16 is apropos downloading to my Pixels as I type these words, in fact), and Samsung had unveiled its own in January (six months later than originally promised, but I digress).

The iPad (finally?) grows up

There is, however, one aspect of Apple’s UI revamp that I’m very excited about, but which ironically has little (but not nothing) to do with Liquid Glass. For many years now, iPads (particularly the high-end Pro variants) have offered substantial hardware potential, largely untapped by the platform’s unrealized software capabilities. Specifically, I’m talking about Apple’s ham-fisted Split View and Slide Over schemes for (supposedly) unlocking multitasking. Frankly, the only times I ever used either of them were accidental, and my only reaction was to (struggle to figure out how to) undo whatever UI abominations I’d unintentionally activated.

Well, they’re both gone as of later this year. In their place is proper MacOS-like windowing, with menu bars, user customizable window locations and sizes, and the like. Hallelujah. Reiterating a point I’ve made before (although software imperfections blunted its at-the-time reality), Apple will need to be careful to not cannibalize its computer sales by tablet sales going forward. That said, as I’ve also previously noted, if you’re going to get cannibalized, it might as well be by yourself, not to mention that tablets offer Apple more competitive isolation than do computers.

Deep learning (local) model developer access

Apple also this week announced that it was opening up developer access to its devices’ locally housed deep learning inference models for use by third-party applications. Near term, I’d frankly be more enthusiastic about this move if the models themselves were better. That said, given that we’re talking about “walled garden” Apple here, they’re the only game in town, so I guess something’s better than nothing. And longer term, Apple now clearly realizes it’s behind its competitors in the AI race and is revamping its management and dev teams in response (not to mention dissing its competitors in the presumed hope of slowing down the overall market until it can catch up), so circumstances will likely improve tangibly here, in fairly short order.

Too much…too little…just right?

By the way, I’m sure many of you have already noticed the across-the-board naming revamp of the various operating systems to a consistent “dominant model year” approach…i.e. although the new versions will likely all roll out later this year, they’ll be majority-in-use in 2026. Whatever (in all seriousness, the numerical disparity between, for example, current-gen iOS 18, MacOS 15 and WatchOS 11 likely resulted in at least some amount of consumer confusion).

Broadly speaking, while I’m not trying to sound like Goldilocks with the header title of this concluding section of my 2025 WWDC coverage, I am feeling a bit of whiplash. Last year, Apple’s event was bloated with unrelenting AI hype (therefore my title “jab”), much of which still hasn’t achieved even a semblance of implementation reality even a year later (to developer and pundit dismay alike). This year, it felt like the pendulum swung (too far?) in the opposite direction, with excessive attention being drawn to minutia such as newly added gestures for AirPods earbuds and the Apple Watch (not that I can even remember the existing ones!), and no matter that the AI-powered real-time language translation facilities are welcome (albeit predictable).

Maybe next year (and, dare I hope, in future years as well) Apple will navigate to the “middle way” between these extremes. Until then, I welcome your thoughts on this year’s event and associated announcements in the comments!

Imec of Leuven, Belgium has unveiled a gallium nitride (GaN) MOSHEMT (metal-oxide-semiconductor high-electron-mobility transistor) on silicon (Si) that achieves both record efficiency and output power for an enhancement-mode (E-mode) device operating at low supply voltage. In parallel, the firm also demonstrated a record-low contact resistance of 0.024Ω·mm, which is essential to further boost output power in future designs. Imec says that the results mark a crucial step toward integrating GaN technology into next-gen mobile devices, particularly those targeting the 6G FR3 band between 7 and 24GHz. The results are being presented at the 2025 Symposium on VLSI Technology and Circuits in Kyoto, Japan, June 8-12...
