Introduction
In addition to a traditional integrating ADC, the Model 2461 Interactive SourceMeter also features a
fast-sampling ADC. The fast digitizing ADC of the Model 2461 allows the instrument to take
measurements at high speed, with capabilities similar to an oscilloscope. This allows you to capture
data at up to one million samples per second and store up to 5 million readings with timestamps. This
feature allows simultaneous current and voltage measurements without any additional hardware, and
offers 18-bit resolution, providing for high accuracy, even at high speed. The fast ADC of the Model
2461 allows this instrument to be used in a broad range of applications, such as negative bias
temperature instability (NBTI) testing and transient thermal analysis.
This example application demonstrates how to use the Model 2461 Interactive SourceMeter
instrument to generate extended operating range, high-power voltage pulses (up to 10 A at 100 V),
and capture both the current and voltage waveforms of high-power pulses. This technique is useful
for testing and troubleshooting the transient response of high-power devices.
Equipment required
One Model 2461 1 kW Pulse Mode Interactive SourceMeter

Instrument
For front-panel connections, use four insulated banana cables, such as the Keithley Instruments
Model 8608 High-Performance Clip Lead Set (one set included with the Model 2461; you will
need another set)
For rear-panel connections, use one Model 2460-KIT Screw-Terminal Connector Kit (provided
with the Model 2461), or you can use one set of Model 2460-BAN Banana Test Leads/Adapter
Cables (with appropriate connections to the device)
One GPIB, USB, or ethernet cable to connect the Model 2461 to a computer
