Scope-based diagnosis of three-phase motor drives
Ordinary oscilloscopes can view basic parameters in modern motor drives, but operational insights generally require specialized power analyzers. Variable frequency drives (VFD) generate carefully controlled pulse-width modulated (PWM) waveforms to modulate the speed of industrial ac motors. Often, the motors involved are three phase. Three-phase ac induction motors (ACIMs) are widely used though they are […]

Wi-Fi 7 front-end modules target automotive, IoT apps
New RFFE modules are designed for Bluetooth, Wi-Fi 6E, and the next-generation standard, Wi-Fi 7. The modules are designed for a wide array of device segments beyond smartphones – including automotive, XR, PCs, wearables, mobile broadband, IoT, and more. “With Qualcomm Technologies’ new products, we are extending our RFFE leadership into automotive and IoT, helping […]
Measuring power choke inductances
The inductance of power chokes changes with current level. Conventional small-signal-measuring bridges are out of their depth here! Hubert Kreis, ed-k • Alan Lowne, Saelig Co. Inc. With the exception of air-core coils, all power inductances show a saturation behavior; their inductance drops with rising current. The core materials can lose permeability and then behave […]
Voltage level translator for SIM card interface circuits
The HL5301 is a subscriber identity module (SIM)/smart card level translator that provides the level shifting and IEC61000-4-2 electrostatic discharge (ESD) protection for SIM card ports. The HL5301 device integrates two unidirectional level shifters for the RST and CLK signals, and bi-directional level shifter for IO, and ±8kV ESD protection on all SIM card contacts. […]
Audio measurements for product development
It pays to know the fundamental parameters that quantify the performance of sound equipment. Daniel Knighten, Audio Precision Quantitative, objective audio measurements have a role to play not just during design validation and as a manufacturing quality control tool, but during all stages of product development . They even come in handy during the earliest […]
Package converter technology allows use of SMT devices on through-hole PCBs
A new adapter for the three-pin TO-205AF packaged MOSFET device allows use of the equivalent product in an SOIC package to be used in PCBs developed for TO packages. The PC-SOT23-TO39-01 is mapped specifically for the Microchip N-channel logic level MOSFET 2N6901. These adapters use an Ironwood-exclusive technology that allows a highly reliable and cost-effective […]
EMI testing for IoT transceivers
A few oscilloscope measurements can give insight into sources of electromagnetic interference that garble the operation of wireless IoT devices. Examine a typical wireless device with an internet of things connection and you’ll likely find multiple RF receivers squeezed together in close proximity onto a circuit board. Cramped quarters characterize modern IoT electronics, so sensitive […]
What you need to know about error analysis in PCIe 6.0 Designs
The much-awaited next generation of PCIe makes it important to understand bit error-rate measurements. Hiroshi Goto, Anritsu Co. PCI Express (PCIe) 6.0 is being developed to meet the high-speed data transmission needs of emerging applications, particularly data centers supporting 5G. It features a doubling of data rates and other enhanced performance specs but at a […]
