The FS4120 Universal Serial Bus (USB) analysis probe is targeted at engineers involved with debugging, testing, verification, and compliance testing of USB 2.0 peripherals and USB-based systems. Designed for use with Agilent Technologies logic analyzers, the probe provides an electrical and mechanical interface between the USB device-under-test and the logic analyzer for passive bus analysis testing. Two separate measurement ports enable designers to independently measure a high-speed device and a full-speed device simultaneously. Key features of the probe include: complete USB serial-to-parallel decode, providing a protocol view of bus traffic; test points for dc current, inrush current and suspend current measurements for self-powered devices; support for both USB 1.1 and 2.0; operation at all USB speeds of 480, 12 or 1.5 Mb/s; and SMA connections for easy triggering and connection to a high-speed oscilloscope. The software included with the probe contains complete configuration files and a USB-protocol inverse assembler for the Agilent logic analyzers. List price of the probe is $7,995.
