Keithley offers free graphing tool for switch/multimeter
-- Test & Measurement World, 6/30/2009 9:00:00 AM
Keithley Instruments has added a Web-browser-based multichannel graphing toolkit to its Series 3700 System Switch/Multimeter family. The new data-visualization capability, which is included at no charge in the firmware of all Series 3700 mainframes, offers an easy way to observe measurement data-versus-time as channel measurements are made with the optional built-in digital multimeter, without the need for programming or any data-file manipulation.
According to the manufacturer, this early-look capability makes it easy for users to gauge the progress of long-duration tests and take corrective action if measurement results are not as anticipated. You do not have to write code in Keithley's TSP script language, LabView, or Visual Basic programming environments, nor extract data from an instrument's reading buffer into a third-party analysis package or spreadsheet to create graphs.
The graphing toolkit lets you observe the data acquired either in numerical form or in graphical form on your choice of up to 40 channels simultaneously. Acquired data can be viewed in real-time mode or in user-defined increments. This simplifies comparing and contrasting readings on a per-channel basis and allows identification of potential problems.
The new capability leverages the Series 3700's compatibility with the LXI standard by expanding upon the built-in instrument control Web page included with many LXI instruments. It comes with the mainframe's firmware and can be accessed via any standard Web browser, including Internet Explorer and Firefox.
Owners of existing Series 3700 mainframes can download a free firmware upgrade at www.keithley.com/products/switching/switchcontrolmainframes/?path=3706/Downloads.
