Smart-device app for source-measure unit (SMU) instruments
IVy, which is the first app developed for SMU instruments, extends Keithley’s Touch, Test, Invent design philosophy to offer benchtop Series 2600B instrument users a fast, easy-to-use touchscreen tool for characterising 2- and 3-terminal devices. By using the power of smart mobile devices, IVy transforms the Series 2600B into a powerful instrument that enables users to visualise, interact, and share measurement results more efficiently, while helping them gain a deeper understanding of their devices’ behaviour.
Unlike other instrument apps, IVy is more than just a tablet/smartphone version of a front panel. IVy uses a smart device’s built-in display (pan/pinch/zoom/swipe), computing (interaction with the instrument), and communication (WiFi, email, etc.) capabilities so users can visualise measurement data, interact with the instrument, and share results – all without programming. The IVy app is designed to help instrument users "learn faster, work smarter, and invent easier." It helps users gain deeper insight into their device under test (DUT) performance by allowing them to toggle quickly between test modes, observe a DUT’s response over time, and analyse results interactively by using fingertip control. IVy is compatible with any Android (V 4.0 or later) smartphone or tablet and the latest release (V 3.1.0) of the Series 2600B firmware (available at www.keithley.com).
IVy’s design provides for simultaneous control over the source level (using an on-screen slider) and monitoring of test results (on the smart device’s graphical display). This capability makes it easy to analyse I-V characteristics, DUT stability, response time, or drift in a circuit visually. Changes in DUT performance are reflected instantly on the graphical display, and further analysis or troubleshooting is simplified by pinching, zooming, or scrolling. IVy also simplifies the process of sharing test results by using built-in smart-device capabilities such as cellular, WiFi, Bluetooth, email, or other apps such as Dropbox and Google Drive.
The Keithley Series 2600B SourceMeter SMU instruments are available in both single- and dual-channel models that combine the capabilities of a precision power supply, true current source, 6½-digit multimeter, arbitrary waveform generator, pulse generator, and electronic load in one integrated instrument. They offer resolution of up to 0.1fA and dynamic range of up to 3A or 200V.
The IVy Android-based app will be available for download at no charge from Google Play later this autumn. Visit www.keithley.com/ivy to receive early notification of its availability or for additional information and pricing on Series 2600B SourceMeter SMU instruments.
