Configuring and connecting the USB interface
Select the appropriate USB class for communication from the utility menu.
• USB- TMC stands for USB Test and Measurement Class. USB-TMC is a 
protocol built on top of USB that allows GPIB- like communication with 
USB devices.
• USB- CDC stands for USB Communications Device Class. USB- CDC is a 
composite Universal Serial Bus device class. It provides a single device 
class, but there may be more than one interface implemented such as a 
custom control interface, data interface, audio, or mass storage related 
interfaces. To install the USB- CDC driver, see the USB- CDC Driver 
Installation Guide in the U3606A Product Reference CD- ROM.
Then, connect the instrument to your PC using the USB 2.0 cable included 
with the instrument.
• To easily configure and verify an interface connection between the 
U3606A Multimeter|DC Power Supply and your PC, refer to the 
USB/LAN/GPIB Interfaces Connectivity Guide, located in the Keysight 
Automation-Ready CD-ROM, which is shipped with your instrument.
