Acquisition Modes
DPO – Captures and displays complex waveforms,
random events and subtle patterns in actual signal
behavior. DPOs are able to 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.
WaveAlert ™ – Monitors the incoming signals
on all channels and alerts the user to any wave-
form that deviates from the normal waveform
being acquired.
Sample – Sample data only.
Envelope – Max/Min values acquired over one or
more acquisitions.
Average – Waveform data from 2 to 512
(selectable) acquisitions is averaged.
Single Sequence – Use the Single Sequence
button to capture a single triggered acquisition
sequence at a time.
Trigger System
Main Trigger Modes – Auto (supports Roll Mode
for 40 ms/div and slower), Normal.
B Trigger – Trigger after time or events.
Trigger After Time Range – 13.2 ns to 50 s.
Trigger After Events Range – 1 to
9,999,999 events.
External Trigger Input – >1 MΩ in parallel with
17 pF; Max input voltage is 150 V
RMS
.
Trigger Types
Edge – Conventional level-driven trigger. Positive or
negative slope on any channel. Coupling selections:
DC, noise reject, HF reject, LF reject.
Video – Trigger on all lines, odd/even or all fields.
With TDS3VID or TDS3SDI trigger on individual
lines and on analog HDTV formats (1080i, 1080p,
720p, 480p).
Logic –
PATTERN: Specifies AND, OR, NAND, NOR when true
or false for a specific 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).
Pulse –
WIDTH (or GLITCH): Trigger on pulse width less than,
greater than, equal to or not equal to a selectable
time limit ranging from 39.6 ns to 50 s.
RUNT: Trigger on a pulse that crosses one thresh-
old but fails to cross a second threshold before
crossing the first 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.
Comm (Requires TDS3TMT) – Provides isolated
pulse triggering required to perform DS1/DS3
telecommunications mask testing per ANSI T1.102
standard.
Alternate – Sequentially uses each active channel
as a trigger source.
TDS3000B DPO provides breakthrough test
speeds for telecommunications line card
testing. The telecom QUICKMENU puts all
the commonly used telecom testing func-
tions on a single menu. Custom video trigger allows the TDS3000B
to trigger on standards such as RS343
(26.6 kHz scan rate). Trace and identify ITU-R BT.601 video
signals with the TDS3SDI 601 serial digital
video module.
