Operable by touch and/or hardware hot-keys independently, the WT5000 offers a seamless and intuitive experience that makes connecting, configuring and measuring easier than ever before. The 10.1 inch WXGA touchscreen delivers excellent noise immunity even in high noise environments such as motors and inverters.

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.

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. Electric and hybrid car manufacturers therefore need to accurately evaluate motor and inverter control in order to achieve higher precision and greater efficiency.
