Tektronix Inc. has announced the DPO4000 digital phosphor oscilloscopes (DPOs), a portable series of models developed upon a new generation platform.
The DPO4000 oscilloscope family ranges from 350 MHz to 1 GHz and is the first to offer Wave Inspector, a set of easy-to-use tools for discovery and efficient viewing, navigating, and analyzing waveform data. The DPO4000 performs serial triggering, protocol decode, has USB plug-and-play PC connectivity, a 10.4" XGA display, and a small footprint. It is targeted at the debug needs of embedded systems design engineers.
Embedded systems have traditionally communicated with each other and the outside world using wide parallel buses. Increasingly, embedded systems designs are replacing parallel buses with serial buses such as I2C, SPI, and CAN. On a serial bus, a single signal may include address, control, data, and clock information; the complexity presents significant debug challenges for design engineers.
