DF1 FEATURES
The DF1 Display Formatter provides data-domain display modes in addition to the existing time-domain display of the 7D01 Logic Analyzer.
It adds state table displays with a comparison mode, and a map display. The DF attaches to the left side of the 7D01, forming a three-wide
plug-in assembly, This assembly operates in a 7000-series oscilloscope mainframe to comprise a complete 16-channel logic timing-state analyzer
system.
A microprocessor controlled memory system, contained in the DF1, is capable of recording two 7D01 information records. Portions of both
information records may be displayed concurrently in a state table presentation.
State tables are displayed in terms of either hexadecimal, octal, or binary formats. This data may be displayed in up to two tables of 17 lines of
16-bit words each. The left-hand table displays data currently stored in the 7D01 memory (7D01 display). The right-hand table displays data
that has been transferred from previous 7D01 displays to the DF1 memory (reference display). The DF1 compares the 2 tables and resets the
7D01 when the 7D01 data equals the reference data.
The map function plots a dot display of the 16 data channels in X-Y coordinate points. Each dot location represents one possible combination
of up to 16 inputs to the 7D01

Section 1—DF1
GENERAL INFORMATION
INTRODUCTION
The Operator’s Manual contains information necessary to
effectively operate the DF1 Display Formatter unit and is
divided into three sections: Section 1 provides packaging
for shipment information, specifications, and a list of
standard accessories. Section 2 contains operating infor-
mation. Information concerning available options is located
in Section 3.
The Instruction Manual contains nine sections. Operating
information is covered in the first two sections; servicing
information is covered in the remaining seven sections.
Schematic diagrams are located at the rear of the manual
and can be unfolded for reference while reading other parts
of the manual. The reference designators and symbols used
on the schematic diagrams are defined on the first page of
the Diagrams and Circuit Board Illustrations section.
Abbreviations used in the manuals, except in the parts list
and schematic diagrams, comply with the American
National Standards Institute Y1.1-1972 publication. The
parts list isa computer printout and uses computer-supplied
abbreviations.
GLOSSARY OF TERMS
The following logic terms are used throughout this manual.
Asynchronous Mode—The data is acquired by the 7D01
using its internal clock at a rate selected by its sample
interval control.
Bit—The smallest increment of digital information.
Blanked Columns—The columns eliminated from the
memory by the COLUMN BLANK function.
Compare—A check between the 7D01 memory and the
reference memory for equality (a microprocessor function.)
Data—This is information acquired by the 7D01. Up to 16
channels of data may be acquired, and each data bit is one
clock period in the synchronous mode.
Data Record—All of the information stored in the 7D01
memory or the DF1 memory. (A Data Record has 4096
bits of information.)
Data Word—This is Good Data that may be formatted in
any of three different ways:
1. A vertical slice of the Timing Diagram display.
2. A coordinate point of the Map display.
3. A horizontal line of characters in a State Table
display.
NOTE
Channel 0 is the top-most channel displayed in
TIMING DIAGRAM format and is always
considered the least significant bit.
Don‘t Care Data—Invalid Data that is excluded from
comparison in all comparison modes.
End Data—Data that fills out the last portion of a table
when valid data ends before completion of the table. This
is indicated by an ‘‘*” in the display.
Good Data—All data which is not Invalid Data.
Indeterminate Data—This is valid data but is considered
invalid because its location cannot be defined. This data is
indicated by an ‘’X” in the display and occurs during sweep
retrace in Timing Diagram. The number of Indeterminate
Data bits for each position of the 7D01 bits/channel switch
are: Two bits (254 bits/channel position), four bits (508
bits/channel position), and eight bits (1016 bits/channel
position),
Invalid Data—This term describes a combination of Indeter-
minate Data, Old Data (if any), and End Data.
New Data—The most recent acquisition of Good Data into
the 7D01.
Old Data—Data which was part of a previous Data Record
in the 7D01 memory but is out of sequence. This is caused
by the arrival of the trigger before the New Data has
completely filled the memory. Old Data is indicated by an
“Xin the display.
Reference State Table—A display of DF1 memory data
transferred from a previous 7D01 display and displayed on
the right half of the crt.
Synchronous Mode—The data is acquired by the 7D01
using an externally supplied clock signal (7D01 sample
interval switch set to external, and with the external clock
signal connected to the clock input of the channel 0-7
Data Acquisition Probe).
Word—See Data Word.

General Information—DF1
INSTALLATION
The DF1 Display Formatter attaches to the left side of the
7D01 Logic Analyzer to make a three-wide plug-in system.
The two units latch together to provide a rigid instrument
that plugs into a 7000-series mainframe. Refer to Figure 1-1
to attach the DF1 to the 7D01.
a)
To prevent instrument damage, plug-in units
should not be installed or removed without first
turning off the mainframe power.
To install the DF1/7D01, first turn off the power to the
oscilloscope mainframe. Then, gently push the 2 plug-in
units into the appropriate plug-in compartments until they
fit firmly. The front panels of the DF1/7D01 should be
flush with the front panel of the oscilloscope mainframe.
NOTE
When installed in a four-compartment main-
frame, the DF1/7D01 occupies the left vertical,
right vertical, and A horizontal compartments
only. The oscilloscope mainframe vertical mode
switch must be set to right and the horizontal
mode switch must be set to A.
To remove the DF1/7D01, pull the release latch (located
on the lower left corner of the 7D01) to disengage the
DF1/7D01 from the mainframe. Then, gently slide the
plug-in units from the mainframe.
PACKAGING FOR SHIPMENT
If this instrument is to be shipped for long distances by
commercial transportation, it is recommended that the
instrument be packaged in the original manner for maxi-
mum protection. The carton and packaging material in
which your instrument was shipped should be saved and
used for this purpose.
