Model 2651A High Power System SourceMeter® Instrument User's Manual Section 7: Increasing SMU current sourcing ability
Equipment needed for this example
To run this test, you will need the following equipment:
•
Two Model 2651A High Power System SourceMeter
®
Instruments
•
One Series 2600A System SourceMeter
®
Instrument; for this application, Series 2600A System
SourceMeter
®
Instrument refers to any of the following instrument models: Models 2601A/2602A,
2611A/2612A, or 2635A/2636A.
•
Two TSP-Link
®
cables (Keithley Instruments part number CA-180-3A)
•
One GPIB cable or Ethernet cable to connect one Model 2651A to a computer
•
Additional cable and connector assemblies as required to make connections to the device under
test (DUT) (for example, Model 2651A-KIT and Model 2600-KIT); see
(on
page 7-4) for a schematic of required connections
NOTE
The Model 2651A High Power System SourceMeter
®
Instruments must be at the same firmware
revision.
Set up communication
The communication setup is illustrated in the following diagram. GPIB is used as an example, but this
application can be run using any of the supported communication interfaces for the instruments. A
TSP-Link
®
connection enables communication between the two instruments. Commands for the
Model 2651A SMU #2 (node #2) and the Series 2600A SMU #3 (node #3) are sent over the TSP-Link
interface.
