Analysis probe
The FS4120 universal serial bus (USB) analysis probe is designed for use with Agilent Technologies' logic analyzers. The probe provides an electrical and mechanical interface for passive bus analysis between the USB device-under-test and the logic analyzer. It has test points for DC current, inrush current, and suspend current measurements for self-powered devices. SMA connectors allow oscilloscope triggering and measurements. Key features include USB serial-to-parallel decode, dual-channel operation with time-correlated displays for hub analysis; external power supply connection for USB devices; error detection for problems such as bad PID, invalid PID, serial bit stuffed, CRC, start of frame, and USB reset; operation at all USB speeds; and support for all types of data transfers. In addition, the FS4120 has two separate measurement ports. This enables the designer to measure a high-speed device and a full-speed device at the same time. The probe comes with software that contains configuration files and a USB-protocol inverse assemble for Agilent logic analyzers. The FS4120 is available now for $7,995.
