Preface

Conventions

The following typographical conventions are used in this manual:
H Names of front-panel controls and menu item names are in bold with the

same case (initial capitals or all upper case) as they appear on the unit itself.

For example, SETUP, Sub-sequence.
H Sections 2, 3, and Appendix B describe the instrument functions by using a

table to list a sequence of steps. Each operating procedure is presented in

order, starting with step 1, and progresses until the end of the procedures.

Execute the action in the top-left table entry first. Then execute actions from

left to right along each row. When you are done executing the steps in one

row, move to the left end of the next row down, and continue executing the

listed steps until the end of the table.
H When steps require that you make a sequence of selections using menu

buttons, an arrow ( ! ) marks each transition between menu buttons. Refer

to Menu Notation on page 2-14 for further information.

For pop-up menus, use the general-purpose knob to select items from the

menu list. Operations, such as Operation 6 (below), do not involve pressing

the buttons shown in the row above, but rather are descriptions of operations

to be performed.

Product Description

This section provides the following information:

H Description and features of the DG2040 Data Generator
H Initial inspection procedure
H Standard and optional accessories listings
H Installation procedures
H Power on and off procedures
H Repackaging procedure for shipment

The DG2040 Data Generator is a programmable data generator with a 2-channel
data output pattern memory. It accommodates a 4k-step sequence controller,
which enables the generation of data patterns longer than the pattern memory and
also the dynamic change of the patterns due to the external events. The operating
parameters, the channel configuration, and the pattern data are displayed or set
using the graphic menu on the CRT monitor. The menu has a tree structure and
can be operated easily using the bottom and side bezel switches.

Main Features

The DG2040 can be manually controlled from the front panel or remotely
programmed via GPIB or RS-232-C.

The DG2040 Data Generator includes the following main features:

H Maximum data rate of 1.1 GHz
H 256 K word pattern memory
H Flexible sequence looping (which does the equivalent of over a billion word

patterns)

H Two channels (complementary) providing the following:

Variable output levels (from –1.125 V to +3.5 V into 50 W)
Edge Control function (CH0 only)
Delay setting (10 ps resolution)

H Parallel and serial pattern editing

DG2040 Data Generator

1Ć1

Getting Started

Any memory size from 360 words to 256 K words can be used with no
restrictions within that range. Each of the two bit data channels can be assigned
to any output channel. The output channels support the setting of high and low
output voltage levels, delay time, and edge position.

The DG2040 Data Generator also provides a 4000-step sequence controller,
which enables the generation of a data pattern longer than the pattern memory
and dynamic pattern changes triggered by external events.

The DG2040 Data Generator provides flexible data editing functions, including
word and line unit input and extended data creation functions. Also, the DG2040
Data Generator provides a set of functions required for system construction, such
as a sequencing function and a jump function using external input.

Applications

Initial Inspection

The following lists some of the DG2040 Data Generator applications:
H Supports subassembly and system testing by simulating the digital signals

from incomplete sections of a product
H Performs margin tests by using the DG2040 Data Generator to generate

patterns that have a low probability of occurrence or are difficult to generate
H Constructs interactive digital simulation systems by using the sequence

output, external jump, and tristate control functions
H Uses flexible data output functions to make the DG2040 Data Generator an

ideal data generator for simulation of semiconductor devices and drivers

specific to serial data communication and all types of digital circuits.
H Performs various timing analysis and jitter/wander tests by using the edge

control function to generate jitter on all the edges or selected edge(s)

Inspect the DG2040 Data Generator shipping carton for external damage.
Remove the DG2040 Data Generator from its package and check that it has not

been damaged in transit. Verify that the carton contains the basic instrument and
its standard accessories. Refer to Accessories on page 1-5.

1Ć2

This instrument was thoroughly inspected for mechanical and electrical defects
before shipment. It should be free of scratches and meet or exceed all electrical
specifications. To confirm this, after inspecting the instrument for physical
damage incurred in transit, test the electrical performance by following the
procedures in Appendix B: Performance Verification. Contact your distributor if
you find a discrepancy.

Options

Getting Started

This subsection describes the options available for the DG2040 Data Generator.
The following options are available:

Option 1R (Rack mounting)
Option D1 (Test result report)

Each of these options is discussed in detail in the following paragraphs.

Option 1R (Rack Mount)

Option D1 (Test Result

Report)

Installation

Environment

When ordered with option 1R, the DG2040 Data Generator is shipped configured
for mounting in a 19-inch rack. The floppy disk drive is moved so that it can be
accessed from the front panel in this instrument.

If you need to configure a standard DG2040 Data Generator for mounting in a
19-inch rack refer to Table 1-4 Optional accessories on page 1-6 for the
Tektronix part number for the rackmount kit.

A calibration data test result report will be provided with the DG2040 Data
Generator when this option is specified.

Before you begin the installation, refer to the General Safety Summary at the
front of this manual for power source, grounding, and other safety information.

Verify that you have the correct operating environment.

CAUTION. Damage to the instrument can occur if this instrument is powered on
at temperatures outside the specified temperature range.

DG2040 Data Generator

The DG2040 Data Generator operates correctly in ambient temperatures from
+10_ C to +40_ C and in relative humidity from 20% to 80%. For more
operating environment information, refer to Appendix A: Specifications.

NOTE. If you are installing the instrument in a dedicated rack, refer to the
instruction sheet that comes with the rack mounting kit for proper installation
procedures.

Verify that there is at least 2.5 cm (1 inch) of clearance on top and bottom, 15.0
cm (6 inches) on the left and right sides, and 7.5 cm (3 inches) at the rear of the
instrument to allow for heat dissipation. Verify that the air intake holes on the
sides and bottom of the cabinet are not obstructed.

1Ć7

Getting Started

Check Fuse

Check the fuse to be sure it is the proper type and rating.

StartĆUp Diagnostics

Power Off

ON/STBY Switch

Figure 1Ć2: Location of the ON/STBY switch

The DG2040 automatically runs diagnostics when the instrument is powered on
from the ON/STBY switch. These diagnostics check whether the instrument is
performing within its defined operating characteristics. If all the diagnostic items
have been completed without error, the instrument displays the EDIT menu.

NOTE. If the instrument chassis temperature is outside the specified operating
range, an error will occur during the power-up diagnostics. If this happens,
power off the instrument, wait until the chassis temperature is within normal
operating range, and then power on the instrument again.

If an error is displayed, contact your Tektronix Field Office or representative.

To power off the DG2040 Data Generator, press the ON/STBY switch.
