The system power management interface (SPMI) protocol is one of the more important enablers of longer battery life in mobile devices. And since we just released support for SPMI decoding on our MXO series oscilloscopes, I thought now might be a good time to produce a short technical introduction to SPMI as well 🙂 https://lnkd.in/eFTDSmaa

Just a reminder that my webinar "Serial Protocol Fundamentals" is coming up this Thursday, July 11th, at 2:00 EST. If you're interested in a gentle introduction to the three most common low-speed serial protocols (UART, SPI, I2C), please register using the link below! https://lnkd.in/e4naj-dY (Bonus points for decoding the UART message exchange in the picture 😉 )

UART, I2C, and SPI have been the backbone of low-speed serial communications since the 1980s and are still very widely used today. If you're interested in learning more, I'm presenting a webinar on all three next month! https://lnkd.in/e4naj-dY

Do you recognize this connector? Despite being older than many of the people using it, GPIB is alive and well, and it's still supported even on our newest test and measurement instruments. If you're interested in learning about how GPIB is used for remote control and test automation, please see my latest video "Understanding GPIB" on the Rohde & Schwarz YouTube channel! https://lnkd.in/eBMmSGRw

When I was studying engineering, I supported myself in part by working as a translator, so localization of content is something that I both personally understand and strongly encourage. 🙂 Some of my videos from the Test and Fundamentals video series on YouTube have already been translated into multiple languages (such as Spanish and Japanese), but if anyone has any suggestions about additional languages we should consider, please let me know!

Only a week and a half to go before my May 21st webinar "The Role of Amplifiers in High Power RF Component Characterization." In the spirit of international understanding, I decided to include both a yardstick and a meter stick in this photo of our ultra-compact SAM100 system amplifier 🙂 https://lnkd.in/eRgh9WYY

Characterizing high power RF components doesn't just require an amplifier: it requires an understanding of the different types of component tests (burn-in, etc.), the types of measurements made on amplified signals, and the importance of different amplifier specifications or settings. I'm presenting a webinar on this topic next month, so if you're interested in learning more, please sign up using the link below! https://lnkd.in/eRgh9WYY

The Test and Measurement Fundamentals videos are now featured on the Microwave Journal University page! https://lnkd.in/exC9tgQE https://lnkd.in/ePSd9dmw Both the links take you to a list of selected videos from the Test and Measurement Fundamentals playlist on the Rohde & Schwarz YouTube channel. (And they chose some of the best ones 🙂 )
