•
Interpolation: Linear, (sinx)/x

Triggering System

•
Modes: Normal, Auto, Single, and Stop
•
Sources: Any input channel, External, Ext/10, or line; slope and level are unique to each source (except line)
•
Coupling Mode: GND, DC 50 ohms, DC 1 Mohms, AC 1 Mohms
•
Pre-trigger Delay: 0 to 100% of memory size (adjustable in 1% increments or 100 ns)
•
Post-trigger Delay: 10,000 divisions in real time mode; limited at slower time/div settings
•
Holdoff by Time or Events: 1 ns to 20 s or from 1 to 99,999,999 events
•
Internal Trigger Range: ±4.1 div from center (typical)
•
Trigger and Interpolator Jitter: </= 3 ps
•
Maximum Trigger Sensitivity with Edge Trigger (Ch1-4 + external):
44Xi
2 div @ < 400 MHz
1 div @ < 200 MHz
•
Maximum Trigger Frequency with SMART Trigger (Ch1-4 + external):
44Xi
400 MHz
@ >/= 10 mV
•
Trigger Level DC Accuracy: ±4% of full scale ±2 mV (typical)
•
External Trigger Range: EXT/10 ±4 V; EXT ±400 mV

Basic Triggers

•
Edge/Slope/Line: Triggers when the signal meets the slope and level condition.
•
Width: Triggers on positive or negative pulse widths selectable from 500 ps to 20 s or on intermittent faults
(subject to bandwidth limit of oscilloscope).
•
Pattern: Logic combination (AND, NAND, OR, NOR) of 5 inputs (4 channels and external trigger input – 2
Ch+EXT on WaveRunner 62Xi). 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 the pattern.
•
State or Edge Qualified: Triggers on any input source only if a defined state or edge occurred on another
input source. Delay between sources is selectable by time or events.
•
TV: Provides stable triggering on standard or custom composite video signals. Use them on PAL, SECAM, or
NTSC systems. Optional HDTV Trigger for 1080i, 1080p and 720p formats along with non-standard formats
up to 2000 lines.

SMART Triggers

•
Dropout: Triggers if the input signal drops out for longer than a selectable time-out between 1 ns and 20 s.
•
Glitch: Triggers on positive or negative glitches with widths selectable from 500 ps to 20 s or on intermittent
faults (subject to bandwidth limit of oscilloscope).
•
Signal or Pattern Interval: Triggers on intervals selectable from 1 ns to 20 s.
•
Runt: Trigger on positive or negative runts defined by two voltage limits and two time limits. Select between 1
ns and 20 s.
•
Slew Rate: Activates a trigger when the rising or falling edge of a pulse crosses two threshold levels, an
