High-speed, high-current pulses from a remote interface ......... 9-4
Introduction
This example application demonstrates how to use the Model 2460 High-Current Interactive
SourceMeter
®
instrument to generate high-current pulses (up to 7 A) and measure voltage.
Making pulsed I-V measurements may be necessary to avoid self-heating effects, device damage, or
to observe the response of a device to a pulsed signal.
In this example, the trigger model controls the timing. The minimum pulse width and period may vary
depending on the magnitude of the current. If you pulse low current (less than 1 µA), you may need to
use a longer pulse width to get a settled voltage measurement. We recommend that you use an
oscilloscope to verify the timing accuracy when you troubleshoot your code.
Equipment required
•
One Model 2460 High-Current 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 2460; you will
need another set)
•
For rear-panel connections, use one Model 2460-KIT Screw-Terminal Connector Kit (provided
with the Model 2460), 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 2460 to a computer
