Sweep Modes Auto, triggered, single
Trigger Coupling dc, ac (7 Hz), low frequency reject (50 kHz), high frequency reject (50 kHz).
Trigger Holdoff Range 60 ns - 320 ms
Trigger Modes Edge, Glitch, Pattern, State, Delay by Time, Delay by Events, Violation (
Setup/Hold Time, Pulse Width, Transition), Video, Line.
Glitch Select positive or negative polarity, width. Captures glitches as narrow as 500 ps.
Pattern Select inputs as High, Low or X (don’t care) to create pattern. Trigger when
pattern is entered, exited, present > t, present < t, or present over a range of
time. Captures patterns as narrow as 500 ps.
State Select one channel as clock, specify other inputs as High, Low or X.
Logic Type: AND or NAND
Delay by Time Time: 30 ns to 160 ms. The trigger is qualified by an edge. After the delay, a
rising/falling edge on any one selected input will generate the trigger.
Delay by Events Events: 1 to 16,000,000 rising or falling edges. The trigger is qualified by an edge.
After the delay, a rising/falling edge on any one selected input will generate the
trigger.
Violation Trigger Setup/Hold Modes: Setup, Hold or Setup and Hold.
Select Clock, Thresholds, setup and/or
hold time.
Pulse Width Triggers on pulse width >t, or <t.
Captures pulses as narrow as 500 ps.
Transition Select Rise Time or Fall Time,
present > t or present < t, thresholds.
Accuracy (time) for glitch, pulse
width, and time-qualified pattern
1.5 ns - 20 ns: ±(20% setting + 500 ps)
20 ns - 160 ms: ±(3% setting + 2 ns)
Video Triggering 525 lines/60 Hz (NTSC), 625 lines/50 Hz (PAL), 875 lines/60 Hz. Trigger on Field 1
or Field 2, any line. User defined triggering: User can specify sync pulse level,
width and polarity, edge number.
