USB GPIB emulation technology licenses

Supplier News

AGILENT Technologies has obtained a patent that describes a method of using the universal serial bus (USB) to communicate with a message processing device, that includes some aspects of GPIB emulation.

USB is a popular, easy-to-use industry standard for connecting peripherals to PCs and laptops. Agilent provides USB capability in its test instruments and I/O converters.

Agilent applied for the patent in December 2000 and was issued US patent 6,718,412 B2 on April 6, 2004.

Agilent's interest was to protect the integrity of this technology pending the adoption of a test and measurement class specification within the USB Implementers Forum.

Mark Pierpoint, vice president of Agilent's Measurement and Analysis Software Group, said USB was a critical I/O capability for test instrumentation.

"The necessity to ensure code communication quality across this bus ensures its present and future utilisation in electronic test systems."

Agilent will offer licenses to this patent to implement this test and measurement class specification. To request a license, access www.agilent.com/find/USBpatentlicense.
