Jitter measurements are important when developing
circuits with serial high-speed data interfaces such as USB 2.0 and HDMI. One
particular challenge is the signal's embedded clock that is used as a time
reference. Rohde & Schwarz addresses this requirement with new options for
its R&S RTO high-performance oscilloscope.
To
measure signal integrity reliably, developers need a powerful T&M
instrument. The R&S RTO features an impressive low-noise frontend, high
dynamic range ADC, high acquisition and analysis rate and a digital trigger
system with extremely low trigger jitter. In addition to automatic jitter
measurements, the new R&S RTO-K12 jitter analysis option offers a wide
range of intelligent functions. For example: A wizard-driven menu assists users
with the most important measurements in order to obtain quick results.
Configurable software clock data recovery (CDR) was implemented for the
automatic time interval error (TIE) measurement function. The track function
shows the progression of measured values and their time correlation with the
trace, opening up additional analysis options. Geometric box elements help
users quickly create mask tests.
The new R&S RTO-K13 option’s configurable hardware CDR is integrated into the oscilloscope’s ASIC. This fully-integrated solution is the first to enable users to perform realtime triggering and signal analysis based on the embedded clock. Signal integrity on serial high-speed interfaces can be analyzed at a speed of up to 5 Gbps. Histograms and mask tests quickly return reliable results.
The new R&S RTO-K12 jitter analysis and R&S RTO-K13 clock data recovery options are now available from Rohde & Schwarz.
