TLS216 Logic Scope

The TLS216 Logic Scope is a new class of instrument designed to simplify the task of debugging digital hardware. The Logic Scope seamlessly combines in a single instrument the analog acquisition system of a high-speed digital storage oscilloscope (DSO) with the triggering and display systems of a logic analyzer. The 500-MHz bandwidth Logic Scope samples all channels simultaneously at 2 GS/s and has sophisticated time-qualified triggering, a high-resolution color display and an integrated MS DOS-compatible 3.5-inch floppy disk drive.

Sophisticated Triggering to Identify Complex Digital Problems

In addition to edge trigger, most digital signals can be easily captured using pulse, glitch, and pattern triggers. The Logic Scope provides two new trigger resources that allow the instrument to directly trigger on common digital circuit behavior. The industry's first time-interval or sequence trigger type monitors the time between two events, allowing the instrument to easily trigger on setup time violations, hold-time violations, or unexpected propagation delay. The powerful "Time-out" trigger type can be used to capture incomplete handshake sequences or to trigger the instrument when the DUT "hangs".

All of these trigger types let developers identify channel-to-channel relationships, including 16-bit patterns and time-related/time-qualified system faults. The Logic Scope's external trigger input can be used as a "Trigger Arm" to enhance cross-triggering between two instruments, simplifying the task of using a Logic Scope with other test equipment.

2.5-pF, Low-Mass FET Probes Ensure Nonintrusive Connection

The Logic Scope includes a set of 16 specially designed probes that have extremely low probe-tip mass (1.5 grams) and input capacitance (2.5 pF). The P6240 low probe-tip mass ensures that connections made to surface-mount and fine-pitch ICs will be reliable. The low input capacitance, combined with the 1-megohm input resistance, decreases the effect of the probe on the DUT's operation, allowing very accurate measurements to be made with confidence.

These characteristics are made possible by using a "podlet-style" probe-tip design instead of the "pencil-style" design of traditional oscilloscope probes. Employing the de facto industry standard of 0.1-inch spacing between the signal and ground inputs, each 0.1-inch thick podlet can directly attach to the hundreds of readily available IC adapters and clips.

Display

Mixed-Mode Data Display - Logic Scope offers Analog, Timing, and BusForm™ display formats that simplify recognition of digital timing faults and signal anomalies. BusForm display compresses many input signals into the least amount of display area. The acquired data can be displayed in any of the three display modes without reacquiring.

Waveform Style - Dots, vectors, variable persistence selectable from 250 ms to 10 s, infinite persistence, and intensified samples.

Color - Standard palettes and user-definable colors for waveforms, text, graticules, and cursors. Measurement text and cursor colors matched to waveform. Waveform collision areas highlighted with different color. Statistical waveform distribution shown with color grading through variable persistence.

Color Grading - With variable persistence selected, historical timing information is represented by temperature or spectral color scheme providing "z-axis" information about rapidly changing waveforms.

Graticules - Full, grid, crosshair, frame.

Format - YT.

Measurement System

The Logic Scope provides a comprehensive suite of automatic measurements specifically designed to improve efficiency when troubleshooting digital hardware. Twenty-eight onboard measurements, including setup time, hold time, and skew, speed identification of common digital problems. Whereas traditional DSOs confine waveform measurements to establishing the relationship of a single channel to a clock, the Logic Scope simultaneously samples on all channels, so you can see the relationships between multiple channels.
