Getting Started
The SDP2000 Signal De velopment Program is a Microsoft
Windows-based program for creating and downloading signals to the
Tektronix TG2000 Signal Generation Platform.
The most basic way to use the package is to select precompiled
signals from the provided library, and download them to the TG2000.
You can also create custom signals for the TG2000, using provided
equations or equations you create with a compiler, such as Borland
or Microsoft.
You can use serial, parallel, or GPIB communications to download
signals. Files can also be stored on a floppy disk (in the form of
encapsulated DNL files) and loaded into the TG2000 floppy drive.
Signals created at a central location can be copied on disks and
distributed to several remote locations or can be linked over a
network.
The SDP2000 Package
The SDP2000 package contains two parts: the SDP2000 program and
the TGCOMM program.

Tutorials.
Functional Overview
Both the SDP2000 program and the TGCOMM program are installed
when you install the SDP2000 package. The TGCOMM program
operates as a separate Windows application and can run at the same
time as the SDP2000 program.
SDP2000 Editors
The SDP2000 program consists of four editors plus a link to the
TGCOMM communications program. Multiple editors and
documents can be open at the same time.
Format Editor. Use the format editor to chose a format or to creat e
new formats. A format defines the characteristics t hat the signal will
adhere to. The signal format encompasses both the picture scanning
structure (the number of lines per frame, the field rate, and the
field:frame ratio) and the method used to e n code chrominance and
luminance information (GBR; Y,P
Waveform Editor. Use the waveform editor to create or edit equation
(.eqn) files. Equation files describe the line waveforms that make up
test signals for the TG2000. Each equation file describes one
waveform. Equation files are used by the frame editor.
Frame Editor. Use the Frame editor to determi ne whic h horizontal
waveforms will go into the frame and where those waveforms will
go. Frame editor files have the extension .men. After you enter the
desired information in the .men file, you build the frame, and the
Frame editor creates a .cmp file. The .cmp files are used by the
Download editor.

).
SDP2000 User Manual

Operating Basics
Download Editor. Use the Download editor to take the .cmp file
created by the Frame editor and make a download file (.dnl) that ca n
be sent to the TG2000. These files contain records and data for one
or more TG2000 modules. (An entire instrument setup of all the
module signals can be contained within one download file.) You can
also modify existing .dnl files.
Communications. You can download files to the TG2000 using a
serial, parallel, or GPIB port, or a 3.5 inch disk. To connect your
computer to a TG2000, refer to Appendix A: Remote Interface.
SDP2000 File Types
The SDP2000 package contains signal files for the various TG2000
modules. These files are stored on the drive that you select during
SDP2000 installation, in a directory named SDP2000. You can
modify copies of the SDP2000 files, but keep the original files
unchanged.
To locate files, you can use the Windows File Manager or the File
Open command (limit the search to the SDP2000 directory and to
files of the desired type).
Download Files. Download files (.dnl files) are logically organized
sets of compiled signals. You can send part or all of a download file
to the TG2000.
Compiled Signals. Compiled signals (.cmp files) are built by the
Frame editor, using source files. You can use compiled signals to
create your own download files. The .cmp files have a DOS fil e
name, as well as a longer, more descriptive name. You define the
descriptive name by entering it in the frame file (.men) in the
“framename” field.
Source Files. Source files consist of menu files (.men files) and
equations (.eqn files). For digital formats, insert files (.ins files) are
also used as source files, to define the SAV, EAV, and other locations
in terms of sample points.

SDP2000 User Manual
Operating Basics
Menu Files. Menu files (.men files) are Frame editor files that you
can edit. Menu files contain equations. Menu files can also contain
instructions and notes that you provide.
Equation Files. Equation files (.eqn files) define the horizontal
waveform.
Download File Structure
The file structure of a download file determines how the signals are
accessed on the TG2000 screen, so it is important to use a logical file
structure when creating or modifying a download file.
The SDP2000 download files provided with the SDP2000 package
are organized as follows:
1. Module. Corresponds to the TG2000 module (such as AVG1).
2. Signal Set. Corresponds to the television signal format (such as
NTSC or PAL).
3. Button. Corresponds to the type of signal (such as Color Bar)
4. Signal. Lists signals of the specified type (such as 75% and 100%
Color Bars). These are .cmp files.
5. Modified signal. Lists signals that are created by the TG2000.
These signals are dependent on the signal above them. The
modified signal file does not contain all i nformation necessary to
define a signal.
Viewing a Sample Download File
1. From the main SDP2000 window, choose Open from the File
menu. In the File Open dialog box, select the working directory
that you specified during SDP2000 installation. Specify .dnl files
in the “List Files of Type” box to display only download files.

3. Field sweep signals that have frequency markers have been
provided with the SDP2000 program. Open the .men file for a
field sweep signal (such as /sdp/awvg1/525/fldswp10.men)inthe
frame editor.
a. These are fixed markers. However, you can change the
sweep stop frequency, which will affect the marker
frequency. For example, if you start with a field sweep
signal that has a 0 to 30 MHz sweep and markers at 5, 10,
15, 20, and 25 MHz, and you change the sweep stop to 6
MHz, the markers will be at 1, 2, 3, 4, and 5 MHz.
b. Touch HELP to open a help window tha t tells you how to
set the parameters.
NOTE. If you want to create your own field sweep signal with
markers, begin with one of the field sweep signals in the SDP2000
signal library, and change the marker frequency by modifyi ng the
related .eqn and .men files. This task requires an advanced
knowledge of video signals.
4. When you touch QUIT/SAVE, the parameters that you selected
will be stored in the .men file.
5. Build the frame. The markers will appear within the zone plate
signal. If they do not appear, be sure that markers enabl e is
checked in the Signal menu (step a). If you select markers
disable, the marker information you stored in the .men file is still
there, and will reappear when you enable the markers again.

Appendix B: Field Codes
by:x
Type this code to apply the equation to the x line, and every line that
is a multiple of x.
Include:
Type in the name of another .men file that you want to include.
Typing in the .men extension is optional. For example: “VERTINT”
or “VERTINT .MEN”. Note that VERTINT could also reference
another equation file, and so forth.
Format:
The format code is used to change the television format for one field
or frame. This controls only the vertical aspec t of the fiel d or frame;
the equation file controls the horizontal aspect. Figure 5 shows a
sample file called \SDP2000\AVG1\SAMPLE\FRMJIT.MEN. This
file uses the Format code to insert frame jitter (it inserts an extra line
in one of the four frames).
ENDFRAME
All frame files must end with this code, unless they are continued to
another file. If the file is continued, only the last file in the sequence
must end with this code.
CONTINUE
This code is used with the ENDFRAME code for continued files.
Continued frames are used to create motion. The Continue code is
used in the frame file shown in Figure 5.
