Combining accurate power measurements and touch-driven oscilloscope waveform viewing capability in a single instrument, the IntegraVision power analyser is intended for engineers who are designing and testing electronic power conversion systems to access dynamic views of current, voltage and power, in projects such as power inverters or converters, universal power supplies, battery systems, vehicle and aircraft power systems, lighting systems/electronic ballasts and appliances.
Keysight contends that although some available power analysers offer good measurement accuracy, they are cumbersome to use and lack the ability to characterise power consumption under dynamic conditions. Engineers have needed a power analyser to make accurate measurements and an oscilloscope to visualize repetitive and single-shot events such as turn-on and occurrences of transients.
The IntegraVision power analyser has isolated inputs rated up to 1,000 Vrms (Cat II). The instruments offer external sensor inputs and 2A(RMS) and 50 A(RMS) direct current inputs, standard on all channels. The external sensor input supports current probes and transducers up to 10V full scale.
Eliminating a separate oscilloscope in the measurement setup decreases test complexity and reduces configuration time, Keysight says; its IntegraVision power analysers are designed to quickly and interactively measure AC and DC power consumption, power conversion efficiency, operational response to stimulus, and common AC power parameters such as frequency, phase and harmonics – all with 0.05% basic accuracy and 16-bit resolution. The power analyser enables engineers to characterise power consumption under highly dynamic conditions with 5 Msamples/sec digitising rate and 2 MHz bandwidth.
Keysight believes that, “If engineers can use an oscilloscope, they already know how to use this instrument, so the learning curve is minimal. With the touch screen, power measurements are no longer time consuming and tedious.”
With the single unit, you can visualise transients, in-rush current and state changes with a high-speed digitiser that captures voltage, current and power in real time; analyse power losses in the time and frequency domains using full Nyquist-based computations; and examine waveform detail and parameters on the large, high-resolution, touch-screen display.
