USB Remote Control System
The USB (Universal Serial Bus) remote control system provides device control via USB,
which is equivalent to control via GPIB. Connection is made through an interface in
compliance with USBTMC-USB488 and USB 2.0.
USBTMC (USB Test & Measurement Class) is a protocol whose design is based on USB
for communication with a USB device, such as that via GPIB.
System configuration
The USB remote control system controls instruments that use the name “alias.” There is no
such address for GPIB connections.
Use a USB cable to connect the E4981A to an external controller (personal computer).
