Hi, we recently got a Keithley 2611B for I-V measurements of an LED devices. However, it is my first time to use a Keithley 2611B. I need entry level tutorials on how to connect the rear panel to my device to run the basic I-V test. For instance, which port on the rear panel should I use? What kind of cables should I use? 

Best,

Qing

I suggest you examine the Quick Start Guide, User Manual and Reference Manual, in that order.

All those can be downloaded from tek.com:  Manuals for 2611B SourceMeter

Quick Start Guide attached to post.

The instrument is shipped with a mating connector and hood/strain relief for making a cable for the SMU channel.
This connector has simple screw terminals to receive your wires from the LED device.

Both the User and Reference have section on DUT connections with pin identification for the connector, etc.
For LED device, recommend to use 4-wire connections.

If you do not want to fabricate a cable of your own using the supplied mating connector, consider the 2600-BAN cable.
Check that the sheathed 4mm banana connectors that it presents are compatible with your LED connection requirements.
There are numerous banana adapters to clip lead and similar on the open market (Pomona, Mueller, etc.).

How are you planning to operate the instrument?  Manually or software?  Does the SMU need to coordinate with any instrument such as light meter, etc.

If just wanting the SMU to do IV curve and not wanting to write any software, consider the KICKSTARTFL-IVC application module of KickStart.
You can connect the 2611B to the PC on USB, LAN or GPIB and use KickStart.  RS-232 is not supported by KickStart and 2600B.
