Using SICL with USB

This topic provides guidelines for SICL programming of USB instruments that conform to USBTMC (Universal Serial Bus Test and Measurement Class) and/or USBTMC-USB488 (Universal Serial Bus Test and Measurement Class, Subclass USB488 Specification).

USBTMC/USBTMC-USB488 instruments are detected and automatically configured by Keysight IO Libraries Suite when they are plugged into the computer. The Keysight IO Libraries Suite Online Help describes the USB instrument configuration process in more detail.

NOTE: Do not confuse the Keysight 82357 USB/GPIB Interface with a USBTMC device. The 82357 is automatically configured as a GPIB interface, not as a USBTMC device, when it is plugged into the computer. Only USBTMC/USBTMC-USB488 devices will be configured as USB devices by Keysight IO Libraries Suite.

The subtopics are:

• Using SICL to Communicate with a USB Instrument
• Operations Supported on All USBTMC Devices
• Operations Supported Only on USBTMC-USB488 Devices
