TLA7E2 Tektronix Logic Analyzer

The TLA7E2 is a 4 Channel logic analyzer module from Tektronix. A logic analyzer is a type of electronic test equipment that engineers use to capture and display signals from a digital circuit or system. Logic analyzers are useful for measuring data, such as state machine traces, timing diagrams, and protocol decodes. When an engineer needs to view the timing relationship between multiple signals, he or she will use a logic analyzer for signal monitoring over time.

The Tektronix TLA7E2 is a 4-Channel DSO module with a 1 GHz bandwidth, 5 GS/s sample rate, and 15 K memory depth.

The TLA700 Series offers a range of digitizing oscilloscope modules that provide the acquisition capabilities of the world’s best digitizing oscilloscopes, tightly integrated with the TLA700 logic analyzers. The 2 and 4 channel digitizing oscilloscope modules available in the TLA700 Series offer sample rates of up to 5 GS/s and bandwidths of up to 1 GHz, with 15 Kb memory depth per channel at all times.

The digitizing oscilloscope modules offer precise time correlation and flexible cross-triggering with other installed modules.

This enables you to see the quality of critical signals time-correlated with the digital signals represented by the logic analyzer modules.

These modules offer the triggering you expect from a Tektronix digital oscilloscope: Pulse Width, Runt, Glitch, Slew Rate, Logic Pattern, Setup-and-Hold Violation, Edge and Timeout.
