Exclusive oscilloscope for power supply design

Yokogawa has made available an oscilloscope which can capture voltage and current waveforms precisely for testing power measurement problems in power supply design. This new scope features 12-bit resolution with 100 MS/s sampling and 20MHz bandwidth helping accurate measurement of inverter pulse shapes, which can then be used to fine-tune inverter efficiency. Other key features include: 1. Input modules are offered supporting 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%. 2. Can be configured to evaluate single phase and three-phase electrical systems. 3. Support 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. 4. 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”. This is particularly useful for examining transient phenomena and in the design of periodically controlled equipment. 5. A variety of functions including arithmetical calculations, time shifting and Fast F...
