Getting Started
Product Description
The TDSCEM1 Communication Eye-Diagram Measurements Application is a
Java-based application that enhances basic capabilities of TDS oscilloscopes.
The application displays a mask pattern behind the eye-diagram of the communication signal being acquired. This allows you to visually analyze the eye-diagram against the mask pattern. In addition, the application can display other
measurements in a numeric format, as well as saving the information to a data
log file to view on a personal computer.
Figure 1 shows an example of a standard mask pattern, the eye-diagram of an
OC1/STM0 communications signal, and the Results readout.
Figure 1: TDSCEM1 Communication Eye-Diagram Measurements Application
Compatibility
The Communication Eye-Diagram Measurements Application is compatible with
the following Tektronix oscilloscopes:
H All TDS 500D and 700D Digital Phosphor Oscilloscopes with Option 2C
(Communications Signal Analyzer package) and Option HD (hard disk
drive) or Option 2M (hard disk drive plus 8 MB record length); the TDS
oscilloscope must also have firmware version 6.4e and up
H TDS 700C Color Digitizing Oscilloscopes with Option 2C (Communica-
tions Signal Analyzer package) and Option HD (hard disk drive) or Option
2M (hard disk drive plus 8 MB record length); the TDS oscilloscope must
also be serial number B020100 and up, with firmware version 6.4e and up

Product Description
You can also use this application with Tektronix TDS Option 3C (Short-wavelength Fibre Channel Optical Reference Receiver) or TDS Option 4C (Longwavelength SONET/SDH Optical Reference Receiver).
For a current list of compatible oscilloscopes, check the Tektronix, Inc. web site,
http://www.tektronix.com/Measurement/scopes/index.html in the Software and
Drivers category.
Requirements and Restrictions
The TDS Run-Time Environment V1.1.0 and above must be installed on the
oscilloscope to operate the TDSCEM1 application.
The TDS Run-Time Environment V1.2.0 and above must be installed on the
oscilloscope to use the GPIB commands.
Updates Through a Web Browser
You can find information about this and other applications at the Tektronix, Inc.
web site, http://www.tektronix.com/Measurement/scopes/index.html in the
Software and Drivers category. Check this site for application updates that you
can download and for free applications.
To install an application update, you will need to download it from the Tektronix
ftp site to a hard disk, copy it to a blank DOS-formatted floppy disk, and then
install it on your oscilloscope.
NOTE. More information about changes to the application or installation is in a
Readme.txt file on the ftp site. You should read it before you continue.
To copy the application from a web browser, follow these steps:
1. Access the ftp site at ftp://ftp.tek.com/mbd/support/00–index.html#1.
2. Scroll through the files to the TDSCEM1 application, select the file, and
download it to your hard disk drive. If necessary, unzip the file.
3. Copy the application from the hard disk to a blank, DOS-formatted floppy
disk.

TDSCEM1 Communication Eye-Diagram Measurements Application User Manual
Installation
The TDSCEM1 floppy disk contains the Communication Eye-Diagram Measurements Application. You can download updates, if any, from the Tektronix ftp site
through a web browser.
NOTE. To operate the TDSCEM1 application, the TDS Run-Time Environment
V1.1.0 or above must be installed on your oscilloscope. To use GPIB commands,
the TDS Run-Time Environment V1.2.0 or above must be installed.
Installing the Application
To install the application from the floppy disk to your oscilloscope, follow these
steps:
1. Power off the oscilloscope.
NOTE. Additional information about the application or installation is located in a
Readme.txt file on the floppy disk. You should insert the floppy disk into a
DOS-based personal computer and read the Readme.txt file before you continue.
If you are updating the application, the Readme.txt file on the Tektronix ftp site
supercedes the Readme.txt file on the TDSCEM1 floppy disk.
2. Insert the disk in the floppy disk drive and power on the oscilloscope.
NOTE. To verify that the TDS Run-Time Environment V1.1 or above is installed,
watch for the name to appear at the top of the display when you power on the
oscilloscope. If it does not appear, contact your local Tektronix sales office.
After performing the power-up selftest, the oscilloscope automatically begins
the installation procedure.
As the application loads from the disk, the oscilloscope displays a clock icon
to indicate that it is busy. Also, the floppy disk drive LED is on, indicating
activity. If the clock icon continues to display after the floppy disk LED has
gone out, a problem has occurred with the installation. Repeat the above
procedure. If the problem persists, contact your Tektronix representative.
When the installation is complete, an Installation Complete message
displays.

Installation
3. Remove the floppy disk and cycle the power to the oscilloscope.
Connecting to a System Under Test
You can use a P6701B or P6703B optical receiver probe to connect between your
System Under Test (SUT) and the oscilloscope.
To connect the probe between the SUT and oscilloscope, refer to Figure 2 and
follow these steps:
WARNING. To avoid electric shock, you must ensure that power is removed from
the SUT before attaching a probe to it. Do not touch exposed conductors except
with the properly rated probe tips. Refer to the probe manual for proper use.
1. Power down the SUT.
2. Connect the optical receiver probe to CH 1 of the oscilloscope.
3. Press VERTICAL MENU ➞ Probe Functions (main) ➞ Cal Probe (side).
This removes the dark level (Pdark) from the signal which allows the cursors
to read the true signal power levels.
4. Connect the optical receiver probe to a communication signal in the SUT.

Application Menu Structure
There are two types of menus in the application menu structure: main menus and
side menus. Some side menus contain common menu items as shown in Table 1.
Main and Side Menus
The main menu names appear in the bottom of the display and the side menu
names appear on the right side of the display. To see the complete application
menu structure, refer to Figure 18 on page 33.
When you press the front-panel button associated with a main menu, the side
menu changes. In many cases, when you press a side menu, new side menu items
appear. As an example, the next figure shows you how to access the Help
selections through the main Utility menu and the Help side menu.
