TEK TDS694C Digital Storage Oscilloscope

Features

TDS 694C with long record length option (1 M) only. 15,000 points/channel maximum on TDS 684C/680C/654C.

Whether you are working on next generation microprocessor designs, high-speed data communications equipment, or in high-energy physics research, the TDS 694C 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 TDS 694C makes your critical timing measurements with the highest resolution and accuracy - even channel-to-channel measurements made in a single acquisition.

The TDS 600C oscilloscopes incorporate all the advanced trigger features you expect in a high performance oscilloscope: triggering on Glitches, Slew Rate violations, Setup and Hold Time violations, Time Outs, Logic Patterns and States on four channels. For applications where sophisticated multi-channel debugging is required, the TDS 694C can be configured for cross triggering with a Tektronix TLA 700 Logic Analyzer.

The TDS 600C 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 clock-to-data skew on the fastest digital designs. The TDS 694C's companion probe, the P6249, offers small size to reliably contact your high-density 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 TDS 600C offers 29 automatic measurements, with measurement statistics, to make your design verification and characterization job much faster and easier. Available Java-based application packages for Jitter Analysis, Disk Drive measurements and Processor Specification measurements provide customized measurements and analysis capability. The TDS 600C gives you the performance and features you need to get your job done faster and more thoroughly.
