USBTMC (USB Test and Measurement Class) is a set of standard device class specifications, built on top of the USB standard. It is intended as a modern replacement of the venerable IEEE-488 (GPIB) standard, which is based on a large parallel connector. Two standards documents are specified:
- USBTMC specification: specifies the protocol and descriptors that allow communications between devices and client software.
- USB488 subclass specification: this specifies how to send and receive IEEE-488.1 and IEEE-488.2 commands over a USBTMC-based transport.
The standard is freely available from usb.org.
The sigrok project supports USBTMC via the respective libusb-1.0 based USBTMC SCPI backend (optionally the librevisa library also has some support, though this not well-tested).
