Precision Power Scope

Fri, 01/17/2014 - 10:14am


The PX8000 Precision Power Scope from Yokogawa brings oscilloscope-style, time-based measurement to the world of power measurement. Typical application sectors 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 electricity distribution systems. The new instrument has 12-bit resolution with 100 MS/s sampling and 20MHz bandwidth, meaning 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, with a basic accuracy of ±0.1% and can be configured to evaluate single phase and three-phase electrical systems. 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.
