Power Viewer for PZ4000 (DISCONTINUED)
- Math operations of up to 4 megawords per channel
- 16 Math operations
- Math operations and X-Y display possible on any 2 channels from any two PZ4000s
- Trend display of computed values
- Save downloaded data to a file and load previously saved files Save downloaded data in CSV format (excluding trend data), as well as in BMP format
- Read floppy disks containing waveform data (in binary format) saved previously on the PZ4000
- Control up to four PZ4000s via communications (GPIB only)
- Waveform and Measured Value Display
Captured waveforms and measured values can be displayed. You can display any data that you need, zoom in on a particular portion, and draw an X-Y display for desired parameters. - Mathematical Calculation Functions
You can set up to 16 calculations (Math1 to Math16) for the captured waveform data using the same numerical computation functions as provided with the PZ4000. Even with data record lengths of 4 megawords per channel, Power Viewer can display waveforms of calculated values. - Dialog Box for Settings for Math1 to Math16
- Trend Display of Measured Values
The measured values can be displayed as trend graphs, allowing you to check chronological changes of various parameters. - Dialog Box for Trend Graph Settings
Set the data items to be monitored, such as voltage, current, and power for up to 8 trend traces. - X-Y Display
You can view an X-Y display by selecting one parameter from measured-data channels 1 to 8 and calculated-value channels Math1 to Math16, for the X-axis trace.
Setting up the PZ4000
With Power Viewer, you can enter settings on all connected PZ4000s individually from a personal computer, including the ranges, filters, record lengths, observation times, and trigger conditions.
- Dialog Box for Setting Input Ranges
- Dialog Box for Setting Record Length and Time Axis
Measured waveform data and calculated values can be saved to any drive of the computer as waveform (.wvf) files or measured-value (.fld) files that can be opened again in Power Viewer. Data can also be saved as .csv files for manipulation using spreadsheet software such as Microsoft Excel. In addition, the screen image of measured waveform data can be saved as a .bmp file.

Researchers from Universidad de Zaragoza use a Yokogawa Test&Measurement PZ4000 Power Analyzer as an alternative to measure the converter output power of induction cooktops.
In dissertation published by the University of Central Florida on its STARS website, research is conducted using a Yokogawa Test&Measurement PZ4000 R&D Power Analyzer to measure the efficiency and total harmonic distortion (THD) of microinverter operating modes.
