LeCroy WAVESURFER User Manual

Operator's Manual
20 WS-OM-E Rev B
Enhanced Resolution (ERES) -- optional with MathSurfer package: from 8.5 to 11 bits vertical
resolution
Envelope (Extrema) -- optional with MathSurfer package: Envelope, floor, roof for up to 1
million sweeps
Triggering System
Modes: Normal, Auto, Single, and Stop
Sources: Any input channel, External, Ext/10, or Line; slope, level, and coupling are unique to
each source (except Line). Line input is not available for battery or DC operation.
Slope: CH1 to CH4, Ext, Ext/10: Positive, Negative, Window; Line (except DC/battery power):
Positive, Negative
Coupling Modes: AC, DC, HF, HFRej, LFRej (except Line trigger)
Pre-trigger Delay: 0 to 100% of horizontal time scale
Post-trigger Delay: 0 to 10,000 divisions
Holdoff by Time or Events: Up to 20 s, or from 1 to 99,999,999 events
Internal Trigger Range: +/-5 div from center
External Trigger Range: EXT/10 +/-5 V; EXT +/-500 mV
External Trigger Impedance: 50 ohms, 1 Mohms
Basic Triggers
Edge/Slope/Line: Triggers when the signal meets the slope (positive, negative, window) and
level condition.
SMART Triggers -- Standard
Glitch: Triggers on positive or negative glitches with widths selectable from 600 ps to 20 s or on
intermittent faults.
Width: Triggers on positive or negative glitches with widths selectable from 2 ns to 20 s or on
intermittent faults. Includes exclusion mode (trigger on intermittent faults by specifying the normal
width period).
Logic (Pattern): Logic combination (AND, NAND, OR, NOR) of 5 inputs (4 channels and external
trigger input). Each source can be high, low, or don't care. The High and Low level can be
selected independently. Triggers at start or end of pattern.
TV -- Composite Video: Triggers selectable fields (1, 2, 4, or 8), positive or negative slope, for
NTSC, PAL, SECAM, or non-standard video (up to 1500 lines).
