Measuring oscillator jitter
In digital electronics, jitter is a particularly insidious form of noise, to be understood, measured and where possible mitigated. Jitter is short-term, generally considered less that one second, deviation from the design intent. It consists of timing fluctuation in periods or transitions within cycles. An eye diagram tells the whole story. While vertical closing of […]

VIDEO: Power Measurements With Markers In The Tektronix RSA306B Spectrum Analyzer
A Tektronix RSA306B PC-based spectrum analyzer is connected to the output from a Tektronix RTSA V3 Demo Board in order to demonstrate power measurements in the frequency domain. Hi and welcome to our 71st Test and Measurement Video. Today we’ll continue our demonstration of the Tektronix RSA306B PC-based spectrum analyzer connected to the Tektronix RTSA […]
Measuring Ebers-Moll model parameters in transistors
If transistor circuits are to be of any use or amenable to diagnostic procedures, we must be able to model them. Even the best electronic test equipment is useless if we don’t know what to look for in the circuits under investigation. Transistors characteristically have multiple modes of conduction. We can view these phenomena in […]
The challenges of HIL testing and ADAS
Engineers running hardware-in-the-loop simulations face difficulties associated with how to devise sensor signals that truly exercise advanced drive assistance systems. DAVID A. HALL, National Instruments Corp. More than 50 years ago, in 1959, the Cadillac Cyclone XP-74 concept car featured two modified aircraft radars designed to alert the driver about oncoming traffic. Today, an automotive […]
Thermal Imaging camera handles quick temperature checks on PCBs, small electronics
Newark element14, the Development Distributor, is now shipping the new FLIR ETS320 Thermal Imaging camera, designed for quick temperature checks on printed circuit boards and other small electronics in the laboratory and accurate quality assurance and factory acceptance testing. Heat can be an important factor in understanding how a system is functioning and the FLIR […]
Thevenin and Norton help interpret measurement results
Engineers are often tasked with making sense of what initially looks like a tangle of wires, electrical energy sources, and components. Before attacking such situations with scope probes, it’s good to recall a few basics. Thévenin’s Theorem states it is possible to simplify any linear circuit to a single equivalent circuit composed of a single […]
Zuken Announces XJTAG DFT Assistant for CR-8000 PCB design suite
Zuken and XJTAG have entered into a partnership to enhance Zuken’s CR-8000 with a design for test (DFT) capability that will improve test coverage during schematic entry. The capability is based on XJTAG’s DFT Assistant, and will be available later this year as a free plugin for Zuken’s CR-8000 Design Gateway users. CR-8000 is a native 3D product-centric […]
Low-Cost Vector Network Analyzer covers up to 6 GHz
Saelig Company, Inc. has introduced the Pico Technology PicoVNA 106 Low-Cost Vector Network Analyzer – an economical USB-controlled, professional-grade 300kHz to 6GHz Vector Network Analyzer (VNA) with excellent performance, portability, and affordability. Despite its small size and low cost, its full-function, minimal-error, ‘Quad RX’ four-receiver architecture supports both 8- and 12-term calibration without the uncorrectable […]
