Connecting the IR-USB cable
You can use the IR communication link (IR communication 
port, located at the rear panel) and the Agilent GUI Data 
Logger software to control your LCR meter remotely. Hence, 
you can only perform data logging operations in the Agilent 
GUI Data Logger application with the LCR meter connected 
via the USB- IR cable to the PC.
Ensure that the Agilent logo on the U5481A IR- USB cable 
(purchased separately) connected to the LCR meter is facing 
up. Firmly push the IR head into the LCR meter’s IR 
communication port until it snaps into place (see 
Figure 1- 3). 
Refer to the Agilent GUI Data Logger Software Quick Start 
Guide and Help for more information on the IR 
communication link and the Agilent GUI Data Logger 
software.
