Communications Signal Analyzer

CSA7404B

Versatile, High-performance
Real-time Digital Oscilloscopes
Dedicated to Rapid Design
Analysis and Verification of
Communications Signals Up to

2.5 Gb/s Rates (OC-48/STM-16
or Fibre Channel FC2125)

The CSA7404B reduces product devel­opment time by providing one tool that
spans circuit development and physical
layer testing. With this family, engineers
can test designs for compliance to
network communications standards as
well as analyze critical internal parameters
such as signal integrity, timing margins
and jitter.
The CSA7404B has 4 GHz true analog
bandwidth, a 20 GS/s maximum real-time
sample rate and more than 400,000
wfms/s waveform capture rate, enabled

®

by exclusive DPX

acquisition technology,

to rapidly acquire electrical and optical
signal information not revealed with other
analysis tools. Integrated broad wavelength
optical response, clock recovery, serial
pattern triggering and mask testing make
testing faster, easier and more efficient.
Innovative software solutions deliver
domain expertise for advanced analysis
and compliance testing, while the
OpenChoice

®

architecture enables users
to integrate their expertise through the
ability to easily write custom programs
or utilize popular commercial software.
Instrument operation is familiar and intuitive
through direct controls and a graphical
user interface. This unique combination
of superior measurement fidelity, unrivaled
analysis and uncompromised usability
speeds the development of network
communications circuit designs.

MyScope®Custom
Control Windows

MyScope control windows allow you to
build your own control windows with only
the controls, features and capabilities that
you care about and are important in your
job. For the first time you can create your
own personalized “toolbox” of oscillo­scope features. No longer do you need
to search through menus for features or
re-learn how to drive the oscilloscope
after a break from the lab. MyScope
control windows are easily created in a
matter of minutes using a simple, visual,
drag-and-drop process. Once created,
these customized windows are easily
accessed through a dedicated MyScope
button and menu selection on the oscillo­scope button/menu bar, just like any
other control window. You can make
an unlimited number of custom control
windows, enabling each person who
uses the oscilloscope in a shared environ-

ment to have their own unique control
window. Since the control windows are
stored as files on the hard drive, they can
easily be transferred to other TDS5000B,
TDS6000B/C or TDS7000B Series oscil­loscopes, or they can even be e-mailed
to a co-worker around the world when
the need arises. MyScope control
windows will benefit all oscilloscope
users, from eliminating the ramp-up time
that many face when returning to the lab
after not using an oscilloscope for a while,
to the power user who can now operate
far more efficiently. Everything you need is
found in one control window rather than
having to constantly navigate through
menu after menu to repeat similar tasks.

Right Clicks

Right mouse click menus make simple
things as they should be – simple. Right
click menus are context sensitive, meaning
the choices presented in the menu depend

on where you right clicked the mouse.
This makes right click menus extremely
intuitive. Want to change the cursor type?
Right click on a cursor or the cursor read­outs. Want to change the reference levels
of an automatic measurement? Right
click on the measurement. Want to
change trigger parameters? Right click
on the trigger readouts. Want to change
a waveform’s color? Right click on the
waveform handle. Virtually all objects on
the oscilloscope display have right click
menus associated with them that include
all the appropriate actions or features rela­tive to those objects. There are also right
click menus for regions of the display, in
addition to just objects. For example, right
clicking in the main graticule brings up a
menu with choices such as Clear Data,
Default Setup, Autoset, Screen Captures,
Save All Waveforms and Add Screen Text,
providing single click access to many of
your most commonly performed tasks.
