Keysight, Intel certify EM simulation for 18A process technology
Keysight Technologies, Inc. announces that the RFPro electromagnetic (EM) simulation software, part of the Keysight EDA Advanced Design System (ADS) integrated tool suite, is now certified by Intel Foundry for design engineers targeting Intel 18A process technology. The new EM simulation capability, together with process design kits (PDKs) for the Intel 18A circuit and physical designs, enables radio frequency integrated circuit (RFIC) […]
Why does the Fourier transform provide apparently inaccurate results, and what can I do about it? part 2
A bare-bones implementation of the Fast Fourier Transform helps illuminate how to extract frequency information from input data samples. In part 1 of this series, we reviewed the discrete Fourier transform (DFT) and manually calculated one DFT shown in Table 1. Table 1. Manual DFT results DFT input Complex DFT |DFT| 3 12 + j0 […]
Review: Electronic bug and hidden camera detectors
Do you want assurance that cameras embedded in everyday devices don’t spy on you? Then you should check for cameras, SD card slots, and Wi-Fi-connections. We reviewed two devices that help you find those lurking spies. While discovering a hidden camera in an Airbnb, VRBO, or hotel is rare, there have been reports of travelers […]
What is phase noise and how can I measure it? part 2
Phase noise requires more than one instrument unless you use a phase-noise analyzer.
AOC 2023: Exhibits show the latest in military wireless
Washington — The Association of Old Crows (AOC) held its 60th annual convention in Washington during the week of December 11, 2023. EE World was there on December 12. Here is some of what we saw in the exhibit hall. AOC is a defense-oriented conference that focuses on military wireless communications. In addition to product […]
How to test the automotive SENT protocol
Oscilloscopes and dedicated software can help analyze SENT data. In “What is the automotive SENT protocol?” we looked at the Single Edge Nibble Transmission (SENT) protocol, as defined in accordance with the Society of Automotive Engineers (SAE) J2716 standard. We reviewed the SENT message frame, which includes a synchronization/calibration pulse followed by a status nibble, […]
What’s the difference between a USB oscilloscope, spectrum analyzer, and digitizer?
USB oscilloscopes are highly versatile instruments. With the right software, they can perform functions usually reserved for spectrum analyzers and digitizers. In some cases, however, special instruments are needed for optimal results. This FAQ compares the functions of oscilloscopes, spectrum analyzers, and digitizers with USB interfaces. They are called USB devices because they connect to […]
