Time Domain Scan (TDS) and Real Time Scan (RTS) capabilities have been added to the Keysight N9048B PXE Electromagnetic Interference (EMI) receiver that enable real-time measurements and diagnostics for faster electromagnetic compliance (EMC) certification. EMC testing requires detailed and exacting methodologies to ensure that all emissions are accurately measured. Long test times impact test facility […]
Test and Measurement Tips
What you need to know about information theory
A lot of the testing and verification activities of EEs today centers on concepts having a theoretical basis in Claude Shannon’s (of Nyquist-Shannon renown) article titled, A Mathematical Theory of Communication, which appeared in 1948 in the Bell System Technical Journal. Shannon’s full treatise gets to be quite mathematical. Fortunately, some of the fundamental concepts […]
Antenna Array Testing – Conducted and Over the Air: The Way to 5G
5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna […]
Portable power quality analyzer decodes three-phase power problems
The Hioki PQ3198 Power Quality Analyzer can be used for assessing power usage as well as for investigating power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. Hioki portable power analyzers can measure single to three-phase lines with a high degree of precision and accuracy. New features include the ability to […]
Stand-alone module facilitates testing of MIPI-enabled devices
The SV4D is a versatile, high-performance, ultra-compact test module enabling at-speed production testing for MIPI interfaces. Capable of operating independently or within any ATE load board, the SV4D is ideal for deployment at wafer sort as well as final test or system-level test. With up to 4 MIPI transmit or receive ports each containing multiple […]
Economical real-time spectrum analyzer monitors wireless signals in real time
The compact ThinkRF R5x50 Real-Time Spectrum Analyzer series are designed to monitor wireless signals in real-time rather than via progressive scan as with most common spectrum analyzers. Real-time analysis is essential for observing intermittent or frequency-hopped signals. Sleeker, lighter weight, and quieter than their predecessor models, the R5550 and R5750 analyzers offer improved spectral performance, […]
Signal Integrity and high-speed design challenges: interview with Mentor’s Todd Westerhoff
At DesignCon 2019, I met with Todd Westerhoff, HyperLynx high-speed design analysis product manager at Mentor, a Siemens Business. Todd has over 38 years of experience in systems modeling, simulation and signal integrity. Prior to joining Mentor, Todd held senior technical and management roles at SiSoft, Cisco and Cadence. We spent time talking about current […]
On the “edge” of a revolution
New computing architectures are changing industrial applications, impacting the way measurements are made, data is collected, and how it all gets processed. Miles Budimir Senior Editor The Internet of Things (IoT) continues to influence how industrial systems are designed and built. The core of IoT systems is the collection of data at the device level […]
Understanding total harmonic distortion measurements
Most electronics engineers and technicians have a good understanding of total harmonic distortion (THD). But there are a few elusive details that come into play during THD measurements. THD is the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. Properly speaking, the fundamental frequency is […]
Free firmware brings mixed-domain analysis to MSOs
Tektronix today released new firmware for the 5 Series and 6 Series MSO mixed signal oscilloscopes that unlocks a new analysis tool called Spectrum View. A free upgrade, Spectrum View allows you to perform mixed domain analysis on the big, high-resolution displays of the 5 and 6 Series MSOs. This mixed domain capability can be […]
