Specifications
This chapter contains the specifications for the TDS5000 series Digital Phosphor
Oscilloscopes. All specifications are guaranteed unless labeled “typical”. Typical
specifications are provided for your convenience but are not guaranteed.
Specifications that are marked with the n symbol are checked in chapter four,
Performance Verification.
All specifications apply to all TDS5000 models unless noted otherwise. To meet
specifications, the following conditions must be met:
H The oscilloscope must have been calibrated in an ambient temperature
between 20 °C and 30 °C.
H The oscilloscope must be operating within the environmental limits listed in
Table 1--10.
H The oscilloscope must be powered from a source that meets the specifica-
tions listed in Table 1--8.
H The oscilloscope must have been operating continuously for at least 20
minutes within the specified operating temperature range.
H You must perform the Signal Path Compensation procedure after the
20-minute warm-up period, and the ambient temperature must not change
more than 5 °C without first repeating the procedure. See Run the signal
path compensation routine on page 4--6 for instructions to perform this
procedure.
Product and Feature Description
The TDS5000 series Digital Phosphor Oscilloscope family consists of the
models shown in Table 1--1.

Specifications
Acquisition Features
Separate Digitizers. Ensure accurate timing measurements with separate digitizers
for each channel. Acquisition on multiple channels is always concurrent and
supports full bandwidth for single-shot acquisitions on each channel. The
digitizers can also be combined to yield a higher sample rate on a single channel.
Fast Acquisition. Acquire up to 100,000 waveforms per second to see rapidly
changing signals or intermittent signal irregularities.
Long Record Lengths. Choose record lengths from 500 points to up to 100,000
points per channel (up 400,000 points on a single channel). Extend the maximum
record length up to a maximum of 8,000,000 points with memory options.
Peak Detect Acquisition Mode. See pulses as narrow as 400 ps even at the slower
time base settings. Peak detect helps you see noise and glitches in your signal.
Acquisition Control. Acquire continuously or set up to capture single shot
acquisitions. Enable or disable optional acquisition features such as equivalent
time or roll mode.
Horizontal Delay. Use delay when you want to acquire a signal at a significant
time interval after the trigger point. Toggle delay on and off to quickly compare
the signal at two different points in time.
Signal Processing
Features
Average, Envelope, and Hi Res Acquisition. Use Average acquisition mode to
remove uncorrelated noise from your signal. Use Envelope to capture and
display the maximum variation of the signal. Use Hi Res to increase vertical
resolution for lower bandwidth signals.
Waveform Math. Set up simple math waveforms using the basic arithmetic
functions including FFT, or create more advanced math waveforms using the
optional math expression editor. Waveform expressions can even contain
measurement results and other math waveforms.
Spectral Analysis. (Optional) Display spectral magnitude and phase waveforms
based on your time-domain acquisitions. Control the oscilloscope using the
traditional spectrum analyzer controls such as span and center frequency.

Specifications
Display Features
Measurement Features
Color LCD Display. Identify and differentiate waveforms easily with color coding.
Waveforms, readouts, and inputs are color matched to increase productivity and
reduce operating errors.
Digital Phosphor. A Digital Phosphor Oscilloscope can clearly display intensity
modulation in your signals. The oscilloscope automatically overlays subsequent
acquisitions and then decays them to simulate the writing and decay of the
phosphor in an analog oscilloscope CRT (cathode-ray tube). The feature results
in an intensity-graded or color-graded waveform display that shows the
information in the intensity modulation.
Fit to Screen. The Digital Phosphor technology performs the compression
required to represent all record points on the screen, even at the maximum record
length settings.
Zoom. To take advantage of the full resolution of the oscilloscope you can zoom
in on a waveform to see the fine details. Both vertical and horizontal zoom
functions are available.
Cursors. Use cursors to take simple voltage, time, and frequency measurements.
Trigger Features
Convenience Features
Automatic Measurements. Choose from a large palette of amplitude, time, and
histogram measurements. You can customize the measurements by changing
reference levels or by adding measurement gating.
Simple and Advanced Trigger Types. Choose simple edge trigger or choose from
eight advanced trigger types to help you capture a specific signal fault or event.
Dual Triggers. Use the A (main) trigger system alone or add the B trigger to
capture more complex events. You can use the A and B triggers together to set
up a delay-by-time or delay-by-events trigger condition.
Autoset. Use Autoset to quickly set up the vertical, horizontal, and trigger
controls for a usable display.
Touch Screen Interface. (Optional) You can operate all oscilloscope functions
(except the power switch) from the touch screen interface. You can also install a
mouse and keyboard to use the interface.
TDS5000 Series Service Manual

Specifications
Toolbar or Menu Bar. You can choose a toolbar operating mode that is optimized
for use with the touch screen, or a PC-style menu-bar operating mode that is
optimized for use with a mouse.
Open Desktop. The oscilloscope is built on a Microsoft Windows software
platform; the oscilloscope application program starts automatically when you
apply power to the instrument. You can minimize the oscilloscope application
and take full advantage of the built-in PC to run other applications. Moving
waveform images and data into other applications is as simple as a copy/paste
operation.
Dedicated Front Panel Controls. The front panel contains knobs and buttons to
provide immediate access to the most common oscilloscope controls. Separate
vertical controls are provided for each channel. The same functions are also
available through the screen interface.
Data Storage and I/O. The oscilloscope has a removable hard disk drive, a floppy
disk drive, and a CD-ROM reader or optional CD-R/W drive that can be used for
storage and retrieval of data. The oscilloscope has GPIB, USB, Parallel. RS232,
and Ethernet ports for input and output to other devices.
Specification Tables
Online Help. The oscilloscope has a complete online help system that covers all
its features. The help system is context sensitive; help for the displayed control
window is automatically shown if you touch the help button. Graphical aids in
the help windows assist you in getting to the information you need. You can also
access the help topics through a table of contents or index.
