Getting Started
Product Description
The TDSJIT1 Jitter Analysis Application is a Java-based application that
enhances the jitter analysis capability of Tektronix TDS oscilloscopes. The
application offers many of the same timing measurements and two additional
measurements: Cycle-to-Cycle and N-Cycle.
Oscilloscopes can take only one measurement in an acquisition waveform. The
TDSJIT1 application can take and accumulate measurements throughout an
entire waveform.
The application can display the measurement results three ways: as Statistics, in
a Histogram graphical format, or in a Profile graphical format (measurement
versus measurement index numbers).
Figure 1 shows an example of the Histogram format of a period measurement.
Figure 1: TDSJIT1 Jitter Analysis Application
Compatibility
The Jitter Analysis Application is compatible with the following Tektronix
oscilloscopes:
H All TDS 500D and 700D Digital Phosphor Oscilloscopes with Option HD
(hard disk drive) or Option 2M (hard disk drive plus 8 MB record length)
H TDS 600C Digitizing Oscilloscopes with an Option HD (hard disk drive)
H TDS 700C Color Digitizing Oscilloscopes serial number B020100 and up,
with Option HD (hard disk drive) or Option 2M (hard disk drive plus 8 MB
record length), and with firmware version 5.2e and up

TDSJIT1 Jitter Analysis Application User Manual
Installation
This application resides on a floppy disk. You can download updates, if any, from
the Tektronix ftp site through a web browser.
NOTE. To operate the Jitter Analysis Application, the TDS Run-Time Environment
V1.1 or above must be installed on your oscilloscope.
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 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 self-test, 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.
3. Remove the floppy disk and cycle the power to the oscilloscope.

Installation
Updates Through a Web Browser
If there is an update for this application, it will be available from the Tektronix
ftp site. To install an application update, you will need to download it from the
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 TDSJIT1 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.
4. Follow the Installing the Application procedure on page 3.
Equipment Under Test Connections
You can use any compatible probe to connect between your EUT (equipment
under test) and the oscilloscope. The connection is usually to a clock signal.
The Skew measurement requires two channels or two reference waveforms.
WARNING. To avoid electric shock, you must ensure that power is removed from
the EUT 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.
Power down the EUT before connecting the probe to it.
