Your designs may be digital but at today’s speeds, many of your toughest problems aren’t.
Crosstalk noise. Transmission effects. Ground bounce. Not to mention sub-nanosecond edges.
Today’s design problems require high bandwidth oscilloscopes that can measure up to these
challenges. The Digital Real-Time
™
architecture of the TDS 600 Series simplifies capturing inter-
mittent signals or non-recurring problems like glitches or metastable states caused by setup
and hold time violations.
TDS 600 Series provides design engineers excellent single shot accuracy for multi-channel,
high speed signal characterization. Additional features and specifications of the TDS 600 Series
are explained in the TDS Reference section of the Textronix Test and Measurement Catalog or
on the World Wide Web at www.tek.com.
