Yokogawa Meters & Instruments Releases PX8000 Precision Power Scope

Yokogawa Meters & Instruments Corporation announces that it will release the PX8000 Precision Power Scope on January 15. A world first, the PX8000 Precision Power Scope combines power-analyzer and oscilloscope technologies to offer a new dimension in time-based power measurement.

Drawing both on Yokogawa’s world-leading expertise in power measurement and long heritage in oscilloscope design, the PX8000 Precision Power Scope brings oscilloscope-style time-based measurement to the world of power measurement. The PX8000 precisely captures voltage and current waveforms, opening up applications and solutions for a huge variety of emerging power measurement challenges. With the launch of this instrument, R&D professionals need no longer compromise on the need for high-accuracy time-based power measurement – something that conventional power analyzers and oscilloscopes were never designed to meet.

The PX8000 has 12-bit resolution with 100 MS/s sampling and 20 MHz bandwidth. This means that it 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 (higher values are possible with external current sensors), with a basic accuracy of ±0.1% of reading.

The PX8000 has built-in functions for the direct calculation of derived parameters, such as RMS and mean power values, to enable the identification of cycle-by-cycle trends. It also supports the capture of power waveforms over specific periods of time through the definition of start and stop “cursors.” This is particularly useful for the examination of transient phenomena and the design of periodically controlled equipment. To ensure that such equipment complies with energy standards, it is vital to measure power consumption across a range of modes, from “sleep” to full activity – and all the transient states in between.

This new instrument is powered by Yokogawa’s isoPROTM technology, which offers industry-leading isolation performance at the highest speeds. Designed with energy-saving applications in mind, this delivers the performance needed to evaluate high-efficiency inverters that operate at a high voltage, current, and frequency, while achieving the measurement accuracy, stability, and repeatability that Yokogawa is known for. Easy to use and with features that will be familiar to users of Yokogawa’s existing families of power analyzers and oscilloscopes, this instrument has a short learning curve.

Applications for the PX8000 cover everything from renewable power to advanced robotics. Any situation where power consumption is at a premium – which means almost anywhere power is consumed – can benefit from the introduction of its precision measurement and analysis capabilities. Typical applications include inverter and motor testing, reactor loss measurement for inverter boost circuits, transient response measurement for industrial robots, wireless charger efficiency measurement, and voltage and power measurement for electricity distribution systems.
