Yokogawa has developed a new data management software package for use with the company's model 3298 multimedia display tester
The new software downloads measurements from the handheld tester to a PC, and displays data tables, chromaticity diagrams, deviation charts and trend graphs.
It can also read data stored in the display tester's memory.
The program can be used to display data for each measurement parameter - including luminance, contrast, flicker and chromaticity - in table format, as well as saving the data to text files.
A graphing function provides easy-to-understand graphical displays of luminance and chromaticity.
Graphics such as chromaticity diagrams can be copied and pasted to other Windows programs, or printed out as hard copies.
Setting parameters can be saved to files, and memory data can be loaded into tables.
The model 3298 is a quality-of-display instrument designed to test the display screens used in modern multimedia products such as notebook computers, PDAs, games consoles and digital cameras.
The tests carried out by the 3298 could previously be made only on very expensive dedicated optical instrumentation, and the low-cost design of the 3298 makes it practicable to expand this type of quality measurement for applications in development and manufacturing environments.
