New Graphing Toolkit for Series 3700 from Keithley

Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, today announced the addition of a Web-browser-based, multi-channel graphing toolkit capability to its Series 3700 System Switch/Multimeter family. This new data visualization capability, which is included at no charge in the firmware for all new Series 3700 mainframes, offers users a quick and easy way to observe measurement data vs. time as channel measurements are made with the optional built-in digital multimeter, without the need for programming or any data file manipulation.

This "early look" capability makes it easy for users to gauge the progress of long-duration tests quickly, and then to take quick corrective action if measurement results are not as anticipated. There's no need to write code in Keithley's TSP® script language, LabVIEW®, or Visual Basic® programming environments and then to extract data from an instrument's reading buffer into a third-party analysis package or a spreadsheet package such as Microsoft Excel to create graphs. Series 3700 mainframes support high speed, multi-channel measurements.

The addition of the graphing toolkit capability allows users to observe the data acquired either in numerical form or in graphical form on their choice of up to 40 channels simultaneously. The acquired data can be viewed in either real-time mode or in user-defined increments. This simplifies comparing and contrasting readings on a per-channel basis, to allow identifying potential problems quickly. For example, this capability would be useful in applications such as burn-in testing, which could involve monitoring multiple temperature, voltage, and resistance measurements, then looking for trends in the measurements over the course of the test.
