Characteristics
Cont. VIDEO (Optional) –
Trigger on a particular line of individual,
odd/even, or all fields. Trigger on a specific
pixel of a line by using the video trigger with
delay by events.

(studio-quality NTSC) sync
formats.625/PAL: Choose monochrome or
color (studio-quality PAL) sync
formats.HDTV: Choose from 1125/60,
1050/60, 1250/50, and 787.5/60 HDTV for-
mats.
MEASUREMENT SYSTEM
Automatic Waveform Measurements –
Period, frequency, + width, – width, rise
time, fall time, + duty cycle, – duty cycle,
delay, phase, burst width, high, low, max.
min, peak to peak, amplitude, + overshoot,
– overshoot, mean, cycle mean, RMS, cycle
RMS, area, cycle area, extinction ratio
(ratio, dB, %), and mean optical power.
Continuous update of up to four measure-
ments on any combination of waveforms.
Measurement Statistics – Display mini-
mum and maximum or mean and standard
deviation on any displayed single-wave-
form measurements.
Thresholds – Settable in percentage or volt-
age.
Gating – Any region of the waveform may
be isolated for measurement using vertical
bars.
Snapshot – Performs all measurements on
any one waveform showing results from
one instant in time.
Cursor Measurements – Absolute, Delta:
Volts, Time, Frequency, and NTSC IRE and
line number (with video trigger option).
Cursor Types – Horizontal bars (volts), ver-
tical bars (time); operated independently or
in tracking mode.
WAVEFORM PROCESSING
Waveform Functions – Sin(x)/x or linear
interpolation, Average, Envelope.
Advanced Waveform Functions (optional
on TDS 500D) – FFT, Integration, Differentia-
tion.
Arithmetic Operators – Add, Subtract, Mul-
tiply, Divide, Invert.
Autoset – Single-button, automatic setup
on selected input signal for vertical, hori-
zontal, and trigger systems. Also automati-
cally normalizes signals to standard masks
when used with the mask testing option.
Waveform Limit Testing – Compares
incoming or math waveform to a reference
waveform’s upper and lower limits.
Waveform Histograms – Both vertical and
horizontal histograms, with periodically
updated measurements, allow statistical
distributions to be analyzed over any region
of the signal. For histograms on DPO acqui-
sitions, both live and stored, the specified
region can be repositioned and will update
to reflect the underlying 3 dimensional data
base, in both YT and XY modes (32 bits in
shallow mode, 64 bits in deep mode).
Mask Testing (Optional) – In addition to the
standard communication masks in the
instrument, the masks can be edited on the
screen. Together with automatic waveform
scaling, the mask tests give rapid verifica-
tion of a digital bit stream’s conformance to
pulse templates and eye pattern masks. For
optical conformance testing, the internal
Fibre Channel and SONET/SDH optical refer-
ence receiver filters provide convenient test
setup which is compliant to industry stan-
dards.
ZOOM CHARACTERISTICS
The zoom feature allows waveforms to be
expanded or compressed in both vertical and
horizontal axes. Allows precise comparison
and study of fine waveform detail without
affecting ongoing acquisitions. When used
with Hi-res or Average acquisition modes,
Zoom provides an effective vertical dynamic
range or 1000 divisions or 100 screens.
Zoom features not available on DPO opera-
tions.
Dual Window Zoom – Dual graticules simul-
taneously show selected and zoomed wave-
forms. Up to two zoom boxes show areas
on the selected trace that are being magni-
fied, and the two magnified areas can be
overlapped for quick comparison. Color of
zoomed trace matches selected trace.
DISPLAY CHARACTERISTICS
Waveform Style – Dots, vectors, variable
persistence from 32 ms to 10 s, infinite per-
sistence, and intensified samples.
Color (TDS 794D, TDS 784D, TDS 754D,
TDS 724D) – Standard palettes and user-
definable color for waveforms, text, gratic-
ules, and cursors. Measurement text and
cursor colors matched to waveform. Wave-
form collision areas highlighted with differ-
ent color. Statistical waveform distribution
shown with color grading through variable
persistence.
Color Grading (TDS 794D, TDS 784D,
TDS 754D, TDS 724D) – With variable
persistence selected, historical timing
information is represented by temperature
or spectral color scheme (or gray scale on
TDS 580D, TDS 540D, TDS 520D) providing
“z-axis” information about rapidly-changing
waveforms.
Graticules – Full, grid, cross-hair, frame,
and NTSC and PAL (with video trigger
option).
Format –
YT and XY (and XYZ in DPO operation).
Type – 7 in. diagonal, NuColor
™ liquid crys-
tal full color shutter display, 256 color levels
(TDS 700D); 7 in. diagonal, magnetic
deflection, horizontal raster-scan monitor
with P4 white phosphor (TDS 500D).
Resolution – 640 horizontal by 480 vertical
displayed pixels (VGA).
COMPUTER INTERFACE
GPIB (IEEE-488.2) Programmability – Full
talk/listen modes. Control of all modes, set-
tings, and measurements.
