Power Supply Measurement and Analysis with the MSO/DPO Series Oscilloscopes
Power supplies can be found in many different electronic devices, from children s toys to computers and office equipment to industrial equipment. They are used to convert electrical power from one form to another for proper device operation.
A New Approach to Quick, Accurate, Affordable Floating Measurements
Engineers and technicians often need to make "floating" measurements where neither point of the measurement is at ground (earth) potential. This measurement is often referred to as a differential measurement. "Signal common" may be elevated to hundreds of volts from earth.
Ten Fundamentals You Need to Know About Your DC Power Supply
In most circumstances, a power supply output operates in either CV or CC mode. However, there are some unusual circumstances that will cause the power supply to enter a third mode called unregulated (UNR) mode.
Achieve Cleaner Power Signals by Minimizing Common Sources of Noise
When noise is present in test or characterization systems, it often leads to the question of whether the DUT is producing a noisy output in response to a stable input signal or responding to noise at the input.
Source Measurement Unit (SMU) Instruments Simplify Characterizing a Linear Voltage Regulator's DC Performance
This article discusses how to characterize some common DC electrical characteristics of LVRs, including line regulation, load regulation, dropout voltage and quiescent current. These parameters are applicable to qualifying both conventional and LDO LVRs for specific applications.
