PX8000 Named Hot 100 Products
12/4/2014

Yokogawa Corporation of America announced that EDN has named Yokogawa’s PX8000 Precision Power Scope as one of the “100 Hot Products of 2014.” The 2014 EDN Hot 100 highlights the electronics industry’s most significant products of the year based on innovation, significance, usefulness, and popularity. 


The PX8000 brings oscilloscope-style, time-based measurement to the world of power measurement. It can capture voltage and current waveforms precisely, opening up applications and solutions for a huge variety of emerging power measurement problems. The new instrument has 12-bit resolution with 100 MS/s sampling and 20MHz bandwidth. This means that the PX8000 can be used for accurate measurement of inverter pulse shapes, which can then be used to fine-tune inverter efficiency. A choice of input modules covers voltage, current and sensor measurements at voltages up to 1000 V RMS and currents up to 5 A RMS, with a basic accuracy of ±0.1%. Higher currents can be measured with external current sensors. 

The PX8000 can be configured to evaluate single phase and three-phase electrical systems. The PX8000 provides true power measurements with ISO 17025 or NIST Traceable calibration data, and incorporates a number of innovative features that support the crucial measurement and analysis of transient power profiles. It provides simultaneous voltage and current multiplication to give real-time power sampling, supporting both transient measurement (as standard) and numerical values averaged across the sample period. Up to 16 different waveforms – including voltage, current and power – can be displayed side-by-side, giving engineers instant “snapshots” of performance. Powered by Yokogawa’s isoPRO™ technology, the PX8000 offers industry-leading isolation performance at the highest speeds. The isoPRO™ core technology, designed with energy-saving applications in mind, delivers the performance needed to evaluate high-efficiency products that operate at high voltages, large currents and high frequency. 

Typical application sectors for the PX8000 include inverter and motor testing, reactor loss, measurement of inverter boost circuits, transient responses of industrial robots, wireless charger efficiency measurement, and voltage and power measurements in electrical distribution systems.

Bill Gatheridge, Product Manager for Yokogawa’s Power Measuring Instruments, says the development of the PX8000 is part of the Yokogawa commitment to provide electrical power measurement solutions for the design, development and testing of electrical products. The PX8000 goes beyond what any other power measuring instrument can offer, as it addresses many of the requests that current users have asked for many years. It has also been developed to reach new applications which were not around a few years ago and also to anticipate new challenges in years to come. “Of the many thousands of products announced during the past year, the EDN Hot 100 are the products that especially caught the attention of our editors and readers. We are pleased to share the tradition of showcasing these technologies as we celebrate the 21st anniversary of this program,” said Rich Pell, Executive and Chief Technical Editor, EDN.
