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 available at
http://www.tek.com/Measurement/Products/catalog/scopes/tds_series.
