Additional Touch Operations
The operability of the touch panel has been improved. "Time / div" can be set by pinch / out. Also, you can flick the waveform display contents.
Advanced Filtering
In addition to low pass frequency filters and line filters, the WT5000 features advanced filtering capabilities that provide unprecedented control to analyze even the toughest of waveforms with precision.
- Synchronization source filter: Instead of synchronizing to zero crossings, users can select any specific point of the synchronization source signal.
- Enhanced frequency filter: Allows users to simultaneously measure fundamental and switching frequencies without influencing any other parameter.
- Digital Parallel Path filters: Supported by a high frequency anti-aliasing filter, two separate line filters for normal and harmonic measurements ensures accuracy without aliasing in wide band and harmonic measurements. Users can limit the number of harmonic orders to eliminate attenuation in low bandwidth measurements.
Advanced Harmonic Analysis
Evaluate and compare input and output harmonics of inverters, motors or power conditioners up to the 500th order. The WT5000 allows users to not only measure harmonics and power simultaneously but also offers side by side comparison of harmonics from two different input sources.
The effects of noise and aliasing are minimized by antialiasing and line filters with Digital Parallel Path technology allowing simultaneous power analysis of wide band and narrow band components.
Harmonics Regulation Test
Combined with the /G7 option and IEC Harmonic /Flicker measurement software, the WT5000 measured harmonic data can be saved into a PC and tested according to IEC regulations. To support large equipment over 16 A/phase (IEC61000-3-12) the CT200 current sensor model can be used.
- Harmonics: EN61000-3-2, IEC61000-3-2, EN61000-3-12, IEC61000-3-12 and JIS C 61000-3-2
Numeric and Waveform Synchronized Data
The waveform data is streamed without any gaps up to 2 MS/s and is synchronized with the numerical data. Abnormal findings in numerical data can be directly linked and be evaluated in the waveform data. For example, one can find numeric parameter variations caused by the influence of imposed high-frequency noise.
Custom Triggers and Computations
Define and use event triggers and custom computations as per application needs. The event trigger function allows users to set limits to capture readings that fall within or outside a specific range of power, current or other parameters. Users can also define and use up to 20 different expressions for custom calculations. Data that meets the trigger conditions can be stored, printed, or saved to a USB memory device.
Electric Vehicle Development
Overview
Between 16 to 18% of the total charge of an electric car is consumed by electric drive system losses.

Overview:
Why should you be concerned with your product’s power system voltage and current harmonics? From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, compliance is an absolute requirement for entry into global markets. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced. During this webinar, attendees will gain knowledge on the inner workings of harmonics, learn best practices for accurately measuring harmonics, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.
