How to perform cyclic voltammetry measurements
This video demonstrates how to use the 2450-EC Electrochemistry Lab System as a potentiostat to perform cyclic voltammetry from 0V to 0.6V and back to 0V using a 100mV/s scan rate.
Graphical sampling integrated into digital multimeter
Citing a market trend for more accurate low power measurements, Keithley Instruments has launched a graphical sampling digital multimeter. “The time to market pressure on engineers is relentless,” says Peter Bachmeyer, Technical Marketing Manager, EMEA, Keithley Instruments. “Typically with a digital multimer, the engineer only sees a numerical display of test results. They want more.”
Source measure unit extends applications reach
Keithley Instruments has added to its benchtop SMU instrumentation range with a capacitive touchscreen graphical user interface (GUI). It has launched the Model 2460 SourceMeter which offers users higher power sourcing (up to 105V, 7A DC/7A pulse, 100W max.) with 0.012% basic measurement accuracy and 6½-digit resolution, making it ideal for high power, high precision I-V characterisation of modern materials and high power devices.
High power interface panel improves connectivity
Trial and error is never a happy path for test engineers to follow, especially so in the case of characterising high power semiconductor devices. It can be time consuming, expensive and unsafe given the high outputs involved in testing power devices. Enhancements to Keithley Instruments’ Parametric Curve Tracer (PTC) configurations that incorporate high power SourceMeter Source Measure Unit (SMU) instruments indicate a new way forward.
App enables SMU to hook up to smart devices
Keithley Instruments has developed IVy, an Android based app that allows smartphones and tablets to interact with a Keithley Series 2600B SourceMeter SMU instrument via its front panel USB interface. IVy extends Keithley's Touch, Test, Invent design philosophy to offer users of the benchtop instrument a fast, easy-to-use touchscreen tool for characterising 2- and 3-terminal devices.
Keithley test systems win favour with X-FAB
Keithley Instruments has won orders for additional S530 Parametric Test Systems from X-FAB Silicon Foundries. X-FAB, a Germany-based foundry for analogue/mixed-signal devices and micro electro-mechanical systems (MEMS), ordered low power versions of the S530 tester for installation on the main production line at its facility in Kuching, Malaysia, where high voltage S530 systems are already in place.
Programmable DC power supplies measure standby current levels
The Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies from Kethley Instruments are also sensitive measurement instruments with the speed and dynamic range for measuring standby current loads and load current pulses that battery-powered wireless, medical, and industrial devices produce.
Speed-to-answer - differentiating instrument design
Industry studies have recently highlighted significant changes in the test market, including shrinking product design cycles (down by 13% over the last three years) and fewer dedicated test engineers with in-depth T&M backgrounds. In fact, one in five electrical engineers now working started his or her career within the last decade. By Jonathan Tucker, Keithley Instruments.
DC power supplies cover wide range of voltage and currents
Keithley Instruments has added the Series 2260B Programmable DC power supplies, which includes two 360W and two 720W models. The launch, alongside the recent introduction of the Series 2200 family, means that means that Keithley has a range of power supplies that address both low power and high power applications in research design, quality control and production test.
High voltage power supplies meet high energy applications
Keithley Instruments has introduced two high voltage power supplies optimised for high voltage device and materials testing and high energy physics and materials science research. The Model 2290-5 5kV Power Supply and Model 2290-10 10kV Power Supply are well suited for high voltage breakdown testing of power semiconductor components.
GPIB interface enhances control in multi-channel power supplies
Keithley Instruments has added two multi-channel power supplies with GPIB interfaces to its line of programmable DC power supplies. The new models address the need for greater control and communication flexibility in both R&D and production test applications, which GPIB interfaces can provide. Both the Model 2220G-30-1 dual-channel and 2230G-30-1 triple-channel power supplies combine greater output accuracy and lower prices.
GUI-driven tool upgrades parametric test system
Keithley Instruments has upgraded its S530 Parametric Test Systems. A new GUI-driven tool expands diagnostic coverage for all system instrumentation and matrix pathways, providing greater confidence in the health of the system. Additionally, users can run the system verification tool to ensure the S530 is within its published system specifications.

Power Source Meter Targets iPhone Generation
“It’s all about touch screen now,” says Peter Bachmeyer, technical marketing manager at Keithley Instruments as he introduced the Model 2450 Source Meter. Bachmeyer’s argument backed up customer research is that there is a wider spread of engineers using test instruments, and that an intuitive, touch screen instrument meets their needs.
