Description
Description
WTViewerE software enables PC connectivity for Yokogawa power analyzers such as the WT5000, WT3000E/ WT3000, WT1800E/ WT1800 , WT500 and WT300E/WT300 through Ethernet, USB, GPIB or RS232.
With multichannel measurements, multi-unit connectivity and multilingual support, the WTViewerE allows users to easily control, monitor, collect, analyze, and save remote measurements from up to any 4 power analyzers simultaneously.
Furthermore, this software supports the waveform data streaming function using the WT5000.
Real-time Control
WTViewerE allows users to analyze and control remote measurements in real-time or use previously acquired data. In the online mode, users have real time control of measurements from each connected instrument, allowing them to remotely start or stop integration or collect live measurement values. In the offline mode as well users can analyze the latest acquired or previously stored data.
Multichannel Measurements
With the WTViewerE, users can simultaneously view up to 12 waveforms, 8 trends, 8 vectors and 6 harmonic bar graphs in split screen mode or zoom in using cursors for more detail on a particular area of interest. Users can also customize, save and load screen layouts as well as specify the data to be saved in CSV format. The software also allows users to create custom computations combining values from multiple power analyzers.
Multi-unit Connectivity
WTViewerE enables synchronized measurement of up to four WT instruments in any combination regardless of model, element type or optional modules.
The software auto detects connected instruments and displays a list from which users can modify wiring systems, voltage and current ranges, update intervals, synchronization sources, display formats and other measurement conditions.
With customizable split screen display of readings in numeric, bar, trend or vector formats, the WTViewerE simplifies the acquisition, storage and analysis of multichannel measurements from up to 4 power analyzers simultaneously.
High Speed Waveform Capture and Synchronized Measurement of Waveform and Power Parameters
The WTViewerE and WT5000 /DS option (data streaming) enable acquisition of high-speed waveform data at up to 2 million samples per second (2MS/s) and easy synchronized measurement of waveform and power parameters. Acquired data can be saved or output to a CSV file.
The figure on the left shows a waveform acquired by data streaming over a duration of 1 second and the details of the waveform (magnified by 100 times).
Data Streaming Description
This function streams the waveform data measured by the WT5000 (voltage/current used as the base for power calculations or motor rotation speed/torque) continuously to a PC at a sample speed of up to 2MS/s without dead-time. With the WT5000 and a PC, the user can monitor high-speed sampled waveforms or save waveform data for extended time periods.
Since the streamed waveforms are synchronized with power parameters, analysis of both makes it possible to understand changes in the noise on the waveform or in the control state. Through changes in the waveform, more detailed analysis is possible, such as how a change in the noise or control state affect the power value and each parameter.
Ideal for multichannel power measurements
The WTViewerE allows users to :
- Connect, synchronize and configure up to four power analyzers in any combination via Ethernet, USB, GPIB or RS232
- Remotely monitor, collect, and analyze live or stored multichannel measurements in a numeric, bar, trend, or vector formats
- Perform user defined computations combining values from multiple power analyzers.
- Save or load configurations, measurement data, screen layouts and more.
