Characteristics of Transient Response from Industrial Robots
One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.
Reference equipment for power calibration
How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible.
Use built-in calculations to analyze motor rotor position of Brushless DC motors (BLDC) and Permanent Magnet Synchronous Machines (PMSM) and find the relative angle between the rotor and position sensors such as encoders or resolvers
Harmonic content is a key contributor to low power quality and agency standards are written to ensure manufacturers take action to measure and control harmonics.
RTCA Inc, (Radio Technical Commission for Aeronautics) Washington, DC, is a non-profit corporation that functions as a Federal Advisory Committee to the Federal Aviation Administration (FAA). Its recommendations serve as the basis for policy, program and regulatory decisions. Sub-committee SC-135 produces the RTCA/DO-160E document titled Environmental Conditions and Test Procedures for Airborne Equipment. This document defines the test conditions and procedures for testing airborne equipment and is the standard by which Boeing, Airbus and other manufacturers require avionic components and sub-systems to be tested.
The request for lower uncertainties in power measurements are increasing,especially in the transformer industries. Their role is to ensure that the electricity is distributed in an efficient and reliable way.
This white paper describes the WT1800, a precision power analyzer that has been replaced by the WT1800E, a unit with numerous improvements including better accuracy. Please visit the WT1800E product page to learn more about the WT1800E.
To keep pace with the increasing speed of switching devices in inverters, Yokogawa has developed the WT1800 precision power analyzer with 10 times faster sampling speed and 5 times wider frequency bandwidth compared with previous models. Its basic accuracy is 0.15% and the frequency bandwidth of voltage and current is 0.1 Hz to 5 MHz (-3 dB, Typical) including the DC component. With up to six inputs, a single WT1800 unit can measure the efficiency of three-phase inverters. In addition, the high-speed data capturing mode allows the WT1800 to measure transient power. This paper describes the high-speed, real-time power measurement technologies underlying these functions.

How-tos
In this video we demonstrate the GPS data logging capability of the DL350 Portable ScopeCorder. Recording Position, Velocity, and Altitude simultaneously with accelerometers or other analog inputs is simple with the DL350's built-in features.
This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.
In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.
To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.
Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.
The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.
