Yokogawa Launches First Precision Power Scope

By DE Editors

Yokogawa Test & Measurement has released its first Precision Power Scope, the Model PX8000.

According to the company, the PX8000 brings oscilloscope-style, time-based measurement to power measurement. The new instrument has 12-bit resolution with 100 MS/s sampling and 20MHz bandwidth. 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 5A 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.

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 can be displayed side-by-side.

The PX8000 is powered by Yokogawa's isoPRO technology. The instrument also supports the capture of power waveforms over specific periods of time and cycle-by-cycle trends through the definition of start and stop "cursors".

The unit makes it possible to simultaneously measure the harmonic components of voltage and current waveforms as well as the harmonic distortion factor. Harmonic measurements take place in parallel with conventional voltage and current measurements. Harmonics up to the 500th order of the fundamental can be measured.
