TDS694C • TDS684C

Whether you are working on next generation
microprocessor designs, high-speed data
communications equipment or in high-energy
physics research, the TDS694C captures
your fastest signals with the best fidelity and
resolution available. Its 3 GHz bandwidth
preserves your waveform’s fast rising edges
and accurately shows signal details.With
10 GS/s digitizing rate simultaneously on all
four channels and a high-stability timebase,
the TDS694C makes your critical timing
measurements with the highest resolution
and accuracy – even channel-to-channel
measurements made in a single acquisition.

The TDS600C oscilloscopes incorporate all
the advanced trigger features you expect in
a high performance oscilloscope: triggering
on Glitches, Slew Rate violations, Setup-and­hold Time violations, Timeouts, Logic Patterns
and States on four channels. For applications
where sophisticated multi-channel debugging
is required, the TDS694C can be configured
for cross triggering with a Tektronix TLA700
Logic Analyzer.

The TDS600C oscilloscopes give you the total
solution to your digital design characterization
and debugging needs. Now you have the tool
you need to verify design margins, character­ize setup-and-hold times and measure clock­to-data skew on the fastest digital designs.
The TDS694C’s companion probe, the P6249,
offers small size to reliably contact your high­density boards with their fine-pitch, hard to
reach components.The P6249 has short
ground connection to give the maximum
system bandwidth and preserve the details
of your signals.

The TDS600C offers 29 automatic measure­ments, with measurement statistics, to make
your design verification and characterization
job much faster and easier. Available Java­based application packages for jitter analysis,
disk drive measurements and processor
specification measurements provide cus­tomized measurements and analysis capability.
The TDS600C gives you the performance and
features you need to get your job done faster
and more thoroughly.
