Discovering an Intermittent Pulse

Tektronix MSO/DPO5000B Series Infinite persistence, stopped after 10 seconds ✔ >250,000 wfms/s maximum waveform capture rate. ✔ Channels represented with different colors or color intensity grading. ✔ Color or grey-scale intensity grading shows frequency of occurrence.

LeCroy WavePro 7Zi Series Infinite persistence, stopped after over an hour ✗ Waveform capture rate not specified for normal operation. ✗ 2,500 wfms/s maximum waveform capture rate in WaveStream™ Fast Viewing mode. ✗ As shown, few glitches or intermittent pulses are captured, even after over an hour.

Dedicated Front Panel Controls
Tektronix MSO/DPO5000B ✔ Per-channel vertical controls. ✔ Wave Inspector® controls make navigation and search easy ✔ Quick front panel access to Math, Reference, Bus Setup, and Measurements.	LeCroy WavePro 7Zi ✗ Multiplexed vertical controls. ✔ Front-panel WaveScan and Zoom/Math position and zoom controls ✗ Math, Reference, Bus Setup and Measurements are all accessed through Windows UI with touchscreen and/or mouse.

Navigation and Search

Tektronix MSO/DPO5000B Series ✔ Wave Inspector® pan/zoom controls for easy navigation through long records. ✔ Search/Mark controls enable you to search for events of interest, mark them, then navigate through the record mark by mark. ✔ Easily copy setups between trigger and search. ✔ Simultaneously search up to 8 types of events. ✔ View captured serial packets in time-stamped protocol event table format.

LeCroy WavePro 7Zi Series ✔ Front panel zoom controls. ✗ Search limited to a single event. ✗ No search events found counter. ✗ No marks (user or automated). ✗ No copying setups between trigger and search. ✗ Serial decode search available, but completely separate from WaveScan™.

Digital Debug with MSO

Tektronix MSO5000B ✔ Integrated design, with small probe pods ✔ Main digital sample rate of 500 MS/s, with MagniVu sample rate of 16.5 GS/s. ✔ Per-channel digital thresholds enable analysis of multiple logic families. ✔ Typical channel-to-channel skews <200 ps, and analog-to-digital deskew capability provided ✔ Clocked (state) and unclocked (pattern) logic triggering. ✔ Clocked or unclocked parallel bus decode. ✔ Green trace for logic highs (1), blue trace for logic lows (0). ✔ Channels can be displayed as a bus and/or individual signals. ✔ Up to 16 buses available. ✔ Digital channels can be grouped and/or independently moved on the display

LeCroy WavePro 7Zi + MSO adapter ✗ Large external brick form factor, with a bundle of relatively short probe leads. ✗ Digital sample rate varies between models from 1 – 2 GS/s maximum. ✗ Digital thresholds limited to one per 9-channel digital probe pod. Limited ability to analyze multiple logic families. ✗ >1 ns analog-to-digital channel timing skews with no deskew capability affects timecorrelation on the display ✗ No clocked logic trigger. ✗ No clocked parallel bus decode. ✗ No color difference between a logical low and high value. ✗ Channels displayed as a bus waveform or as individual signals, but displaying both consumes 2 of the 4 digital traces. ✗ Maximum of 4 digital traces, including displayed signals. ✗ Digital channels must be displayed in hardware order.
