Precise scope for power

The new instrument, according to Hafeez Najumudeen, Yokogawa Europe's product marketing manager for power meters and analysers, test and measurement: "Builds a bridge to get the best out of both instruments....to deliver a true test and measurement revolution." With a view to addressing Yokogawa's two focus markets of renewable energy and energy conservation, the PX8000 brings oscilloscope-style time-based measurement to the world of power measurement. The new instrument has 12-bit resolution with 100 MS/s sampling and 20 MHz bandwidth. 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 basic accuracy down to ±0.1%. The PX8000 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. Up to 16 different waveforms – including voltage, current and power – can be displayed side-by-side, giving engineers instant "snapshots" of performance. A history memory function automatically records up to 1000 historical waveforms which can be recalled and redisplayed at any time.
