The Yokogawa PX8000 Precision Power Oscilloscope brings together Yokogawa’s world-leading expertise in power measurement with our long heritage in oscilloscope design to deliver a true test and measurement revolution: the world’s first precision power scope.
With the launch of the PX8000, R&D professionals need no longer compromise on their need for high-accuracy time-based power
measurement, a need that conventional power analyzers and oscilloscopes were never designed to meet.
As more and more innovation focuses on energy consumption and the integration of electronics into power-based systems, so more and more engineers are demanding accuracy and precision from their power measurement
R&D teams everywhere are coming to terms with the need for new levels of precision in power measurement. With pervasive microprocessor control and on-going pressure to reduce energy consumption, the lines between electrical and electronic engineering continue to blur – and the need for a new class of hybrid measurement is emerging.
Traditional power measurement instruments cannot provide accurate time measurements; oscilloscopes are not designed to measure power. The Yokogawa PX8000 is the world’s first precision power scope, bringing oscilloscope-style time-based measurement to the world of power measurement.
The Yokogawa PX8000’s time-based accuracy brings a new dimension to power analysis. It can capture voltage and current waveforms precisely, opening up applications and solutions for a huge variety of emerging power measurement problems.
Yokogawa PX8000 Precision Power Oscilloscope for Transient power measurements and analysis
The Yokogawa PX8000 has a number of innovative features that support the crucial measurement and analysis of transient power profiles.
Yokogawa PX8000 Features:
| Simultaneous power calculation | Provides simultaneous voltage and current multiplication to give real-time power sampling. |
| Cycle-by-cycle power trend measurement | Trend measurements between waveforms can be calculated by mathematical functions (up to four million points). |
| Specific time-period measurement | Supports the capture of power parameters over specific periods of time through the definition of start and stop “cursors”. |
| Specified time-period waveform measurement | Supports the capture of waveform parameters over specific periods of time through the definition of start and stop “cursors”. |
| X-Y display and phase analysis | Supports X-Y axis displays as standard. It can also display lissajous waveforms of input and output for phase analysis. |
| Capturing sudden or irregular phenomena | An always-active History function automatically records up to 1,000 historical waveforms. |
| Long-period data capture and analysis | An accompanying PC application called PowerViewerPlus can be used to capture waveform data for further analysis. |
| FFT analysis | Features arithmetical, time-shift, FFT and other computations that enable users to display waveforms with offsets and skew corrections. |
| Simultaneous harmonic measurement | Makes it possible to simultaneously measure the harmonic components of voltage and current waves as well as the harmonic distortion factor. |
| Multifunction snapshots | Up to 16 different waveforms- including voltage, current and power, can be displayed side-by-side, giving engineers instant snapshots of performance. |
| Detailed transient analysis | Supports the measurement of all power waveform parameters between precisely defined start and stop cursors. |
| Trend calculation | Built-in functions for the direct calculation of variables, such as root mean square (RMS) and mean power values, to enable the identification of cycle-by-cycle trends. |
| De-skew compensation | Automatic de-skewing function eliminates offsets between current and voltage signals that may be caused by sensor or input characteristics. |
| Powered by isoPRO technology | Offers industry-leading isolation performance at the highest speeds. Delivers the performance needed to develop high-efficiency inverters that operate at high voltages, large currents, and high frequency. |
