OREANDA-NEWS. Yokogawa has combined its world-leading expertise in power measurement and its long heritage in oscilloscope design to create the world's first Precision Power Scope: the Model PX8000.

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.

In addition to delivering precision power measurement to give true insight into energy consumption and performance, the PX8000 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.

The PX8000 is powered by Yokogawa's isoPRO(tm) technology, which offers industry-leading isolation performance at the highest speeds. isoPRO core technology, designed with energy-saving applications in mind, delivers the performance needed to evaluate high-efficiency inverters that operate at high voltages, large currents and high frequency.
