As the heartbeat of embedded systems,
clocks are critical to maintaining
timing references and synchronization
across components, subsystems and entire
systems. As these examples of measurements
have shown, modern oscilloscopes
offer a broad set of measurements
that take the mystery out of characterizРис.

Fundamentally, jitter is any unwanted
deviation in signal edge timing from
where it should be. Jitter is a fact of life in
the design of embedded systems and
communication links. As such, for systems
to operate reliably under a broad
range of conditions, thorough characterization
of jitter is a must.
With complexity on the rise, modern mixed signal designs are proving to be a worthy adversary to designers. Embedded design engineers are having to wear multiple hats in order to efficiently troubleshoot and debug the latest designs. Debugging today’s designs requires working in a mixed domain environment, from DC to RF, with analog and digital signals, and serial and parallel buses. That means a modern measuring device should be combined and needs to give designers a more comprehensive set of functions and features to support efficient verification and debugging of embedded designs. To meet this need Tektronix has developed a new integrated oscilloscope MDO3000 that combines 6(!) instruments in a single small, portable package able to provide insight into both time and frequency domains.
