Connecting the IR-USB cable
You can use the IR communication link (IR communication port, located at the 
rear panel) and the Keysight GUI Data Logger software to control your LCR meter 
remotely. Hence, you can only perform data logging operations in the Keysight 
GUI Data Logger application with the LCR meter connected via the USB- IR cable 
to the PC.
Ensure that the Keysight 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 Keysight GUI Data Logger Software Quick Start Guide and Help for 
more information on the IR communication link and the Keysight GUI Data Logger 
software.
