4. To acquire a waveform, press [RUN N× SINGLE].
The R&S RTE performs an MDIO decode according to the thresholds and protocol
settings of the associated serial bus source (here in our example SB1).
5. To start searching the acquired waveform for specific events, tap "Enable" in the
search setup dialog.
The R&S RTE displays the "Search Results" box that lists the detected events.
For information on how to configure the search results presentation and how to navi-
gate the search results, see also "To display search zoom windows" on page 466 and
"Navigating search results" on page 447.
13.16 USB (option R&S RTE-K60)
R&S RTE-K60 is a firmware option that enables the R&S RTE to analyze Universal
Serial Bus (USB) protocols, by triggering and decoding them. The option is compatible
with the standards USB 1.0, USB 1.1, USB 2.0 and USB HSIC (High-Speed Inter-
Chip). R&S RTE-K60 supports the data rates "Low Speed" (1.5 Mbit/s), "Full Speed"
(12 Mbit/s) and "High Speed" (480 Mbit/s, available in USB 2.0 and HSIC).

13.16.1 The USB protocol
The USB protocol was developed, starting in 1996, by the nonprofit organization USB
Implementers Forum, Inc. (USB-IF), formed by Compaq, Hewlett-Packard, Intel,
Lucent Technologies, Microsoft, NEC, and Philips. The purpose was to provide a com-
mon "plug-and-play" solution to replace a multitude of interfaces for the communication
between computers and devices. It should allow even unskilled users to easily connect
many devices to a PC. USB was originally used for devices that feature low signalling
rates (up to 1.5 Mbit/s), especially human interface devices like mouse, joystick or key-
board. With the release of USB 2.0 in April 2000, devices such as printers, cameras
and mass storage media were enabled to exchange data at faster rates (up to
480 Mbit/s). Also, the high-speed protocol HSIC (High Speed Inter Chip) is used for the
communication between on-board devices.
