Digital Phosphor Oscilloscopes — TDS3000C Series
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 13.2nsto50s
Trigger After Events
Range
1 to 9,999,999 events
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
fields on NTSC, PAL, SECAM
Extended Video Trigger on specific 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
(or Glitch)
Trigger on a pulse width <, >, =, ≠to a selectable time
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 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
Pattern Specifies AND, OR, NAND, NOR when true or false for
aspecifictime
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
Waveform Measurements
Characteristic Description
Cursors Amplitude, Time
Automatic Measurements Display any four measurements from any combination
of waveforms. Or display all measurements with
measurement snapshot feature. Measurements include
Period, Frequency, +Width, -Width, Rise time, Fall time,
+Duty cycle, -Duty cycle, +Overshoot, High, Low, Max,
Min, Peak-to-peak, Amplitude, Mean, Cycle mean,
RMS, Cycle RMS, Burst width, Delay, Phase, Area*1,
Cycle Area*1
Measurement Statistics Mean, Min, Max, Standard deviation. Requires
TDS3AAM application module
Thresholds User-definable thresholds for automatic measurements;
settable in percent or voltage
Gating Isolate a specific occurrence within an acquisition to
take measurements, using either the screen or cursors
*1Requires TDS3AAM application module.
Waveform Math
Characteristic Description
Arithmetic Add, subtract, multiply, and divide waveforms
FFT Spectral magnitude. Set FFT vertical scale to Linear
RMS or dBV RMS, and FFT window to Rectangular,
Hamming, Hanning, or Blackman-Harris
Advanced Math*1Integrate, Differentiate, Define extensive algebraic
expressions including analog waveforms, math
functions, scalars, up to two user-adjustable variables
and results of parametric measurements. For example:
(Intg (Ch1-Mean(Ch1)) × 1.414 × VAR1)
Note: Requires TDS3AAM application module.
*1Requires TDS3AAM application module.
