Static Power Analysis
Short records, acquired under steady-state operating conditions, can provide fast updates of mean value power quantities in the Numerics table. Power quantities can be calculated on a line frequency AC period, a variable frequency PWM output period, or over a very short time period, such as the device switching period.
Dynamic Power Analysis
Long records permit capture and analysis of long periods of time. Touch a Numerics table cell and create a per-cycle "synthesized" Waveform of the parameter over time. Zoom+Gate adds further value for dynamic analysis. Correlate complex behaviors to other control or power system waveforms, and debug power conversion system problems faster.
Zoom+Gate
Zoom your acquisitions and Gate both the Numerics measurement table and the per-cycle Waveforms to the zoomed area. Gain deeper and faster understanding of complex drive and control system behaviors.
Harmonics Analysis Option
Apply a discrete fourier transform (DFT) harmonic filter to acquired voltage and current waveforms. Harmonically filter Numerics table results more accurately than brute force hardware filters. Display per-order Harmonics in a table along with up to 9 spectral waveforms. View per-cycle THD values over time.
3-phase Vector Display Option
Two simultaneous vector displays permit visualization of three-phase system voltage and current. Vector information can be harmonically filtered and is compatible with Zoom+Gate to show vector changes during dynamic or long acquisitions.
Waveform Transformations option (THREEPHASEdq0)
Support for two simultaneous αβγ (Clarke) and dq0 (Park) real-time transformations with X-Y plot capability available for d vs. q and α vs. β components.
Intuitive, graphical user interface
An easy-to-understand user interface guides the operator through setup and analysis. Setup capability is provided for any combination of single-phase or three-phase system input/output.
