Acquisition Modes
Mode Description
DPO Captures and displays complex waveforms, random
events and subtle patterns in actual signal behavior.
DPOs provide 3 dimensions of signal information in real
time: Amplitude, time, and the distribution of amplitude
over time
Peak Detect High-frequency and random glitch capture. Captures
glitches as narrow as 1 ns (typical) using acquisition
hardware at all time base settings
WaveAlert Monitors the incoming signals on all channels and alerts
®
the user to any waveform that deviates from the normal
waveform being acquired
Sample Sample data only
Average Waveform averaged, selectable from 2 to 512
Envelope Min-max values acquired over one or more acquisitions
Single Sequence Use the Single Sequence button to capture a single
triggered acquisition sequence at a time
Trigger System
Characteristic Description
Main Trigger Modes Auto (supports Roll Mode for 40 ms/div and slower),
Normal, Single Sequence
B Trigger Trigger after time or events
Trigger After Time Range 13.2 ns to 50 s
Trigger After Events 1 to 9,999,999 events
Range
Trigger Types
Trigger Description
Edge Conventional level-driven trigger. Positive or negative
slope on any channel. Coupling selections: AC, DC,
Noise Reject, HF Reject, LF Reject
Video Trigger on all lines or individual lines, odd/even or all
elds on NTSC, PAL, SECAM
Extended Video Trigger on specic lines in broadcast and
non-broadcast (custom) standards and on analog
HDTV formats (1080i, 1080p, 720p, 480p). Requires
TDS3VID or TDS3SDI application module
Pulse Width Trigger on a pulse width <, >, =, ≠ to a selectable time
(or Glitch) limit ranging from 39.6 ns to 50 s
Runt Trigger on a pulse that crosses one threshold but fails to
cross a second threshold before crossing the rst again
Slew Rate Trigger on pulse edge rates that are either faster or
slower than a set rate. Edges can be rising, falling, or
either
Pattern Species AND, OR, NAND, NOR when true or false for
a specic time
State Any logic state. Triggerable on rising or falling edge of
a clock. Logic triggers can be used on combinations of
2 inputs (not 4)
Comm Provides isolated pulse triggering required to perform
DS1/DS3 telecommunications mask testing per ANSI
T1.102 standard. Requires TDS3TMT application
module
Alternate Sequentially uses each active channel as a trigger
source
