Preface

This manual provides information necessary for users or service technicians to verify the performance of the DTG5000 Series Data Timing Generator.

Manual Structure

The DTG5000 Series Data Timing Generator Technical Reference contains the following sections:

The Performance V erification section contains an introduction, a list of equipment required, and procedures that, when passed, ensure that the product meets its specifications.

The Specifications section contains a brief product description and characteristics tables. These tables cover the electrical, mechanical, environmental characteristics and certification.

Performance Verification

Two types of Performance Verification procedures can be performed on this product: Self Tests and P erformance Tests. You may not need to perform all of these

procedures, depending on what you want to accomplish.

 Verify that the DTG5000 Series Data Timing Generator is operating correctly

by running the Self Tests, which begin on page 1-3. Advantages: These procedures require minimal time to perform, and test the

internal hardware of the DTG5000 Series Data Timing Generator.

 If a more extensive confirmation of performance is desired, complete the self

tests, and then do the Performance Tests beginning on page 1-10. Advantages: These procedures add direct checking of warranted

specifications. These procedures require suitable test equipment and more time to execute. (Refer to Equipment Required on page 1-11).

Conventions in this manual

Throughout these procedures the following conventions apply:

 Each test procedure uses the following general format:

Title of Test Equipment Required Prerequisites Procedure

 Each procedure consists of as many steps, substeps, and subparts as required

to do the test. Steps, substeps, and subparts are sequenced as follows:

1. First Step a. First Substep

Performance Verification

 Where instructed to use a control in the display or a front-panel button or knob,

the name of the control, button or knob appears in boldface type.

Menu Selections

User Manual

Install the Output Modules

Instructions for menu selection use the following format: Menu button → Left or right Allow button (by using this button, you can move

to desired menu category) → Upper or down Allow button (by using this button, you can move to desired menu item) → SELECT or Enter key (this completes the selection).

You can use a mouse as a pointer, use keyboard shortcuts for quick operation, or use front panel knob instead of sticking to above menu selection format.

The DTG5078 & DTG5274 & DTG5334 Data Timing Generators Quick Start Manual is strongly recommended to f amiliarize the first-time user with instrument controls and features.

Any output modules ordered are shipped separately. For complete instructions on how to install the output modules, refer to the User Manual. (Output modules do not ship preinstalled.)

CAUTION. Do not install or remove any output modules while the instrument is

powered on. Always power the instrument down before attempting to remove or install any

output module.

Self Tests

Performance Verification

There are two types of tests in this section that provide a quick way to conf irm basic functionality and proper adjustment:

 Diagnostics  Calibration (You must perform this calibration before the performance tests.)

These procedures use internal diagnostics to verify that the instrument passes the internal circuit tests, and calibration routines to check and adjust the instrument internal calibration constants.

NOTE. To perform the Self Tests, at least one o utput module (DTGM10, DTGM20,

DTGM21, DTGM30, DTGM31, or DTGM32) must be installed in the DTG5000 series Data Timing Generator mainframe. You can select any slot when you perform the tests even though the descriptions below are assuming the Slot A is used.

Diagnostics

This procedure uses internal routines to verify that the instrument is operating correctly. No test equipment or hookups are required.

The instrument automatically performs the internal diagnostics when powered on; you can also run the internal diagnostics using the menu selections described in this procedure. The difference between these two methods of initiating the diagnostics is that the menu method does a more detailed memory check than the power–on method.

Do the following steps to run the internal routines that conf irm basic functionality and proper adjustment.

Equipment required

Prerequisites

None

First, at least one output module must be installed properly in the mainframe.

Second, power on the instrument and allow a twenty-minute warmup before doing this procedure.

1. Set up the instrument:

 Confirm that there is no output being performed by v erifying that the RUN

button indicator is not on. If the indicator is on, push the RUN button to turn it off.

DTG5078 & DTG5274 & DTG5334 Data Timing Generator Technical Reference 1-3

Performance Verification

 Verify that the output module LEDs are not on. If any output module LEDs

are on, push the ALL OUTPUTS ON/OFF button to turn the LEDs off.

2. Internal diagnostics: Perform these substeps to verify internal diagnostics. a. Display the Diagnostics dialog box:

 From the application menu bar, select System, and then select

Diagnostics.... The following dialog box appears if you ha ve changed

the settings

 Select OK to display the Diagnostics dialog box. See Figure 1-1.

Figure 1-1: Diagnostics dialog box

 Verify that the Loop until Fail box is not checked. If it is checked,

click the box to remove the check mark.

 Select Execute All It em s to start the diagnostics.

Performance Verification

b. Wait: The internal diagnostics takes one to six minutes. When complete,

the resulting status appears in the diagnostics control window.

c. Verify that no failures are found and reported: All tests should pass.

Confirm that the word Pass appears in all the Status fields. If any failures occur, record the failure information and contact your local Tektronix service personnel for more information.

3. Select Close to exit the diagnostics.

Calibration

Two types of calibrations are provided in the DTG5000 Series Data Timing Generator.

 The Level Calibration uses internal calibration routines that check electrical

characteristics such as DC accuracy of data output, and then adjust the internal calibration constants as necessary.

 The Skew Calibratio n checks the delay time of data output, and then adjust the

internal calibration constants as necessary. The calibration is performed by connecting each channel output to Skew Cal In.

NOTE. Level Calibration and Skew Calibration are not valid until the instrument

reaches a valid temp erature .

Level Calibration.

Equipment required

Prerequisites

None

Power on the instrument and allow a 20 minute warmup at an ambient

temperature between +20 °C and +30 °C before doing this procedure.

The calibration routine must be performed whenever the ambient

temperature changes by 5 °C or more.

1. Set up the instrument:

 Confirm that there is no output being performed by v erifying that the RUN

button indicator is not on. If the indicator is on, push the RUN button to turn it off.

 Verify that the output module LEDs are not on. If any output module LEDs

are on, push the ALL OUTPUTS ON/OFF button to turn the LEDs off.
