3.7 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 trigger).  Inactive channels useable as trigger inputs. 
Slope: Positive, Negative, Window 
Coupling Modes: DC,AC,HFREJ,LFREJ 
  AC Cutoff Frequency   7.5 Hz typical 
  HFREJ, LFREJ    50 kHz typical 
  Pre-trigger delay      0 - 100% of horizontal time scale 
  Post-trigger delay      0 - 10000 divisions 
  Hold-off by time or events  Up to 20s or from 1 to 99,999,999 events 
  Internal trigger range   ±5 div 
Maximum Trigger Frequency: Up to 500 MHz (350 MHz on LT264/262) 
External Trigger Input Range: ± 0.5 V, ± 5 V with Ext 10 
Max external input @ 50Ω: ±5 V DC or 5Vrms 
Max external input @ 1MΩ: 400 Vmax (DC + peak AC < 5 kHz) 
 
3.8 Automatic Setup 
Auto Setup: Automatically sets timebase, trigger, and sensitivity to display a wide range of 
repetitive signals. 
Vertical Find: Automatically sets the vertical sensitivity and offset for the selected channels 
and display a waveform with maximum dynamic range. 
 
3.9 Probes 
Model PP006: PP006 with auto-detect: 10:1, 10 MΩ; one probe per channel  
Probe System: ProBus Intelligent Probe System supports active, high-voltage, current, and 
differential probes, and differential amplifiers 
Scale Factors: Up to 12 automatically or manually selected
