Getting Started

Product Description

The TDSPSM1 Processor Specifications Measurements Application is a
Java-based application that enhances basic capabilities of TDS oscilloscopes.
The application offers many of the same timing measurements, but does not
require any external equipment or lengthy procedures that may be prone to error.

Oscilloscopes can take only one measurement in an acquisition waveform. The
TDSPSM1 application can take and accumulate measurements throughout an
entire waveform effectively taking cycle-to-cycle timing measurements.

The application can display the measurement results in a numeric format as
statistics and in two graphical formats as a histogram or profile plot.

Figure 1 shows an example of the results of a Channel-to-Channel Delay
measurement.

Figure 1: TDSPSM1 Processor Specifications Measurements Application

Compatibility

The Processor Specifications Measurements 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

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 TDSPSM1 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 any compatible probe to connect between your System Under Test
(SUT) and the oscilloscope. The connection is usually to a clock signal.

Most measurements require two waveforms. The AC Timing measurements only
require one waveform.

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.

Power down the SUT before connecting the probe to it.

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 2.

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 32 on page 39.

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.

Using Basic Oscilloscope Functions

You can use the Utility menu to access help information about the application.
You can also use other oscilloscope functions and easily return to the application.

Using Local Help

Returning to the

Application

The application includes local help information about the measurements modes,
with some explanation of the individual controls.

To display the local help, follow these steps:

1. Press Utility (main) ➞ Help (side).

2. Use the side menu buttons to navigate through the help.

You can easily switch between the TDSPSM1 application and other oscilloscope
functions.

To access other oscilloscope functions, press the desired front panel control. To
return to the application, push the SHIFT and then the APPLICATION front­panel menu buttons as shown in Figure 2.

Warning Messages

Operating Basics

Push the SHIFT and then the APPLICATION button to return to the application.

Figure 2: Returning to the application

All timing measurements provide a warning if the input conditions do not
support accurate measurements. For example, the Period measurement warns you
if you do not have at least two cycle-start edges in the acquired waveform.

Configuring the Display

You can change how dialog boxes appear on your oscilloscope, as well as the
color of waveforms. The next figure shows how to access the display options and
