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 environment, 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.
