Little Big Power: Femtoamps and Regenerative Supplies

When power systems get ridiculous… Power goes way beyond basic bench power supplies. Daniel Bogdanoff sits down with Chris Cain to explore femtoamp measurements, 100 kV multi-quadrant regenerative power systems, noise, and space-borne solar arrays in this EEs Talk Tech electrical engineering podcast! Audio: Learn more about the Keysight RP7900 regenerative power systems (RPS) and the Keysight CX3300 Dynamic Current Analyzers 0:17Recording from New Jersey with Chris Cain, who manages teams for electronic industrial products, like power, DMMs, function generators, DAQs, board test, etc. 1:15Current analyzer behind us measures FEMTOAMPERES of current. This is useful for RF and IoT systems. 4:20Chris’s most spectacular equipment failure – a new engineer put their electrolytics in backwards 6:30For extra large electrolytic capacitors people design vent holes in PCB 8:15 High power power supplies. 5kW and 10 kW power supplies 9:00Two quadrant power supplies vs. one quadrant power supplies 10:30A 100 kV power supply!? What’s that used for? Battery emulation for things like electric cars. The supply has to be able to both source and sink power, and switch between the two very quickly 12:15A regenerative power supply (RPS) rectifies input voltage and puts it back on the AC mains instead of dissipating it as heat like a normal electronic load. So, the overall cooling requirements are very different for an RPS than a normal electronic load. One of the big costs for industrial factories is air conditioning and heat management. So, a regenerative power supply is very useful because it reduces heat. 15:15Regenerative power supplies are also useful for testing photovoltaic inverters, for both terrestrial and space solar systems. 18:45Noise parameters for high power systems 20:30Power is very complex, and the systems are very dynamic 22:15Giant toroidal transformers are used for power supplies and are dynamically controlled. They also are leveraged from systems like source measure units (SMUs). 24:30Precision current measurement is very different than measurement, it often uses a triax 25:30Some systems have 5 or 6 wire measurements to help with guardbanding

Little Big Power: Femtoamps and Regenerative Supplies

5G, Beamforming, & MIMO

5G means business. With wired speeds coming in over the air, designers are turning to new wireless techniques like beamforming, MIMO, and advanced tower synchonization designed to pump you full of bits. Find out more as Daniel Bogdanoff sits down with Brig Asay and Joe Haver to discuss the changing wireless ecosystem of tomorrow. Audio: Video: 1:004G was sub 6 GHz, but 5G is much higher frequencies (24 GHz, 28 GHz, 39 GHz, and above 50 GHz) 2:154G test strategies: simple source and a middle-of-the-line signal analyzer. There were also some combo boxes that were both signal sources and signal analyzers. 4:005G testing requires more powerful setups. There are still generators, but they have to be more powerful. FR2, 100 MHz, 200 MHz, 400 MHz wide bands make things more complicated. Chambers and OTA (over the air) testing and MIMO systems make things much more complicated. And, a 5G system has to cover all of these ranges. 5:30MIMO for 5G – MIMO means “Multiple Input Multiple Output” Beamforming is also being implemented. Designers need to be able to test and see all the 5G signals at once. 7:00 Beamforming explanation and discussion – essentially beams can be directed with constructive and destructive interference to send signals to UEs (user equipment). 5G beamforming significantly increases the power delivered to a UE. Want to try it? Try “Build a beam” here: https://www.keysight.com/main/editorial.jspx?cc=US&lc=eng&ckey=2800374 10:005G brings wired-level speeds to wireless systems, which will open up brand new markets that haven’t even been defined yet. 11:155G security 12:00Are 5G bandwidths a challenge? A wider carrier channel means more interference and a lower effective number of bits / SNR (signal to noise ratio). So, the wide 5G bands require a more robust design. This is especially true for distance. Even windows are potentially a challenge with 5G frequencies, so beamforming becomes critical. 15:30Testing 5G with a signal analyzer / spectrum analyzer – is it doable? Sorta… How do you look at four distinct bands at one time? 18:00The UXR oscilloscope can actually look at multiple bands at once at 0.5 EVM (error vector magnitude). 20:00Why does 5G have so many different frequencies and bands? Isn’t that excessive? 21:00Will 5G make it where I can get rid of my home internet provider? 22:00Beamforming from a cell tower is pretty easy, but it’s much harder for a handset. So, there are systems that propose 5G downlinks, but 4G or 3G back up to the tower. 23:00Multiple towers can talk to the same handset AT THE SAME TIME! Multiple towers can provide the same packet at the same time to the same UE to increase the power. This means they are all working on the same clock as well. 25:00There are a number of ways to synchronize multiple cell towers at the same time. GPS is common, but there are a number of other feasible technologies. 27:00Brig has to get in his “vicious Keysight plug” for the mmWave extension on the UXR that lets an oscilloscope behave like a signal analyzer. It also uses a 1mm connector on the front end. 31:45Stupid question: if you had to describe 5G using five words that start with “G” what would they be?

USB 3.2 took 10 Gbps and doubled it to 20 Gbps It’s USB4 not USB 4.0 and not USB 4 (confirmed) 10:00With USB4 you must implement USB-PD (USB Power Delivery), but in the past it was optional.USB4 brings a doubling bitrates, you must use Type C connector, and must be backwards compatible all the way to USB2 13:30USB 3 and USB 3.2 had a lot of alternate modes, but USB4 implements a tunneling mode. With tunneling allows you to send packets of USB, DisplayPort, or PCIe inside of the USB protocol. This means you don’t have to run it as an alternate mode, which requires extra silicon. 17:00The silicon is often prototyped before a spec is actually released, so that the spec can match reality and be possible to build. 18:30USB4 is already being prototyped and tested. At the USB workshop-plugfestUSB plugfests are very secret, and company names aren’t used. They use a “test ID number” instead of company name, and the attendance is very limited. In many cases, only Keysight and the company testing their device are allowed to be in the room while the testing is done. 21:00A “Compliance Test Spec” describes how you test a device against a specification. Because, you can’t test for every single thing in the spec, but you can test a subset of things to verify performance. 22:00 Will USB take over everything? It depends on the other organizations and specifications groups. There are other ecosystems and organizations like VESA (DisplayPort) and HDMI that are autonomous. But, both HDMI and VESA have a USB Type-C mode that allows the protocols to work over a USB Type C connector 26:00USB4 implementation is very complex! The different speeds that could be used are pretty complex. USB4 is advertised 40 Gbps, but it’s actually 20 Gbps x2. 30:15It can be 5 Gbps, 10 Gbps, 20 Gbps, and run at x1 or x2, and it can also do alt modes. 31:55Are there any main competitors to USB4? What about the lightning connector from Apple? 35:30There’s evidence that there will be a USB4 native display, and some high end USB4 monitors already exist. 36:30USB4 is coming, and if you want to be on the leading edge you better get started now (and why)! 38:20 – stupid questions:When will see USB5? What’s the lamest way someone could use USB4? If USB4 is truly universal, shouldn’t it go into space?

One Protocol to Rule Them All!?

USB Type-C brings a lot of protocols into one physical connector, but is there room for oneprotocolto handle all our IO needs? Mike Hoffman and Daniel Bogdanoff sit down with high speed digital communications expert Jit Lim to find out. 0:00 This is Jit’s 3rd podcast of the series 1:00 We already have one connector to rule them all with USB Type-C, but it’s just a connector. Will we ever have one specification to rule them all? 2:00 Prior to USB Type-C, each protocol required it’s own connector. With USB TYpe-C, you can run multiple protocols over the same physical connector 3:00 This would make everything more simple for engineers, they would only need to test and characterize one technology. 3:30 Jit proposes a “Type-C I/O” 4:00 Thunderbolt already allows displayport to tunnel through it 4:30 Thunderbolt already has a combination of capabilities. It has a display mode – you can buy a Thunderbolt display. This means you can run data and display using the same technology 6:30 ...

The Huge Challenge of Testing USB 3.2

USB 3.2 testing is darn hard! We talk compliance test specs, USB 3.2 testing BKMs, and pre-spec silicon. Guest Jit Lim sits down with Mike Hoffman and Daniel Bogdanoff to talk about the new difficulties engineers are facing as they develop USB 3.2 silicon. https://eestalktech.com/wp-content/uploads/2018/08/The-Huge-Challenge-of-Testing-USB-3.2-Electrical-Engineering-Podcast-33.mp3 Agenda: In the last electrical engineering podcast, we talked about how USB 3.2 runs in x2 mode (“by two”) This means there’s a lot of crosstalk. The USB Type C connector is great, but its small size and fast edges means crosstalk is a serious concern. When we test USB, we want to emulate real-world communications. This means you have to check, connect, and capture signals from four lanes. For testing Thunderbolt you always have to do this, too. Early silicon creators and early adopters are already creating IP and chips for a spec that isn’t released yet. 2:00 They’re testing based on the BKM (Best Kn...

USB 3.2 + Why You Only Have USB Ports On One Side of Your Laptop

USB 3.2 DOUBLES the data transfer capabilities of previous USB specifications, and could mean the end of having USB ports on just one side of your computer. Find out more in today’s electrical engineering podcast with Jit Lim, Daniel Bogdanoff, and Mike Hoffman. https://eestalktech.com/wp-content/uploads/2018/08/USB-3.2-EEs-Talk-Tech-Electrical-Engineering-Podcast.mp3 1:00 Jit is the USB and Thunderbolt lead for Keysight. 1:30 USB 3.2 specifications were released Fall 2017 and released two main capabilities. USB 3.2 doubles the performance of USB 3.1. You can now run 10Gb/s x2. It uses both sides of the CC connector. In the x2 mode, both sides of the connectors are used instead of just one. 4:00 The other new part of USB 3.2 is that it adds the ability to have the USB silicon farther away from the port. It achieves this using retimers, which makes up for the lossy transmission channel. 5:00 Why laptops only have USB ports on one side! The USB silicon has to be close to the connecto...

One Protocol to Rule Them All!?

USB Type-C brings a lot of protocols into one physical connector, but is there room for oneprotocolto handle all our IO needs? Mike Hoffman and Daniel Bogdanoff sit down with high speed digital communications expert Jit Lim to find out. 0:00 This is Jit’s 3rd podcast of the series 1:00 We already have one connector to rule them all with USB Type-C, but it’s just a connector. Will we ever have one specification to rule them all? 2:00 Prior to USB Type-C, each protocol required it’s own connector. With USB TYpe-C, you can run multiple protocols over the same physical connector 3:00 This would make everything more simple for engineers, they would only need to test and characterize one technology. 3:30 Jit proposes a “Type-C I/O” 4:00 Thunderbolt already allows displayport to tunnel through it 4:30 Thunderbolt already has a combination of capabilities. It has a display mode – you can buy a Thunderbolt display. This means you can run data and display using the same technology 6:30 ...

The Huge Challenge of Testing USB 3.2

USB 3.2 testing is darn hard! We talk compliance test specs, USB 3.2 testing BKMs, and pre-spec silicon. Guest Jit Lim sits down with Mike Hoffman and Daniel Bogdanoff to talk about the new difficulties engineers are facing as they develop USB 3.2 silicon. https://eestalktech.com/wp-content/uploads/2018/08/The-Huge-Challenge-of-Testing-USB-3.2-Electrical-Engineering-Podcast-33.mp3 Agenda: In the last electrical engineering podcast, we talked about how USB 3.2 runs in x2 mode (“by two”) This means there’s a lot of crosstalk. The USB Type C connector is great, but its small size and fast edges means crosstalk is a serious concern. When we test USB, we want to emulate real-world communications. This means you have to check, connect, and capture signals from four lanes. For testing Thunderbolt you always have to do this, too. Early silicon creators and early adopters are already creating IP and chips for a spec that isn’t released yet. 2:00 They’re testing based on the BKM (Best Kn...

USB 3.2 + Why You Only Have USB Ports On One Side of Your Laptop

USB 3.2 DOUBLES the data transfer capabilities of previous USB specifications, and could mean the end of having USB ports on just one side of your computer. Find out more in today’s electrical engineering podcast with Jit Lim, Daniel Bogdanoff, and Mike Hoffman. https://eestalktech.com/wp-content/uploads/2018/08/USB-3.2-EEs-Talk-Tech-Electrical-Engineering-Podcast.mp3 1:00 Jit is the USB and Thunderbolt lead for Keysight. 1:30 USB 3.2 specifications were released Fall 2017 and released two main capabilities. USB 3.2 doubles the performance of USB 3.1. You can now run 10Gb/s x2. It uses both sides of the CC connector. In the x2 mode, both sides of the connectors are used instead of just one. 4:00 The other new part of USB 3.2 is that it adds the ability to have the USB silicon farther away from the port. It achieves this using retimers, which makes up for the lossy transmission channel. 5:00 Why laptops only have USB ports on one side! The USB silicon has to be close to the connecto...
