This whitepaper includes a review of differential pair properties and how they differ between tightly and loosely coupled pairs. Also a description of test set-up used to look at signal integrity through several different differential pair architectures. The results are then shown and the information is concluded. ...
Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...
Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools.
VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs...
This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This...
This in-depth white paper guides you through the choices and weighs key design considerations to help you pick the right transceiver. It reviews the most typical RS-485 ICs and explore the most common design considerations. Then it examines electrostatic discharge (ESD) protection and compare the Human Body Model (HBM)...
The explosive growth in Internet-connected devices, or the Internet of Things (IoT), is driven by the convergence of people, device and data across the web. Future growth will be strongly influenced by wearable technology as products transition from the laptop to the pocket to the body.
Activity trackers are leading...
Though they seem like minor components on a smartphone, automotive dashboard or other consumer electronic device, tactile switches have the ability to influence perceptions of quality. True or not, a bad switch equals a bad device in the minds of many consumers.
So selecting the right switch really can be crucial...
It is important to confirm the AC voltage, frequency, and phase when selecting a power supply as these differ from region to region. If more than the specified level of voltage is applied, the power supply can be damaged. If the input voltage has a distorted wave, the unit will either not operate normally or will suffer...
Most organizations do not consider production test a top priority, but it is a necessity to prevent major quality issues in the products that represent the company brand in the hands of customers.
The costs, however, can be significant and are often greatly misunderstood, especially when there’s no easy way...

It is absolutely necessary to use code-compliant power strips in patient care vicinities to minimize the risk of potentially harmful shocks. UL 60601-1 power strips with fault protection are uniquely suited for standalone use in patient care vicinities, but misleading marketing and labeling makes it difficult to distinguish...
For testing new designs of battery holders, MPD fabricated min-max sized battery slugs. The slugs proved to be a great aid to our engineering staff in several ways. First off is saving time and money by not having to shop for several brands of batteries to confirm that your design works with common batteries.
They...
Power design in data centers is getting substantial attention—particularly by facilities and engineering personnel—as organizations pursue constant improvements in reliability and energy efficiency.
At the same time, however, many IT professionals tend to spend little time or energy on the specific products...
