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.

Operating Instructions—DF1
DETAILED OPERATING INSTRUCTIONS
POWER-ON MODE
When power is applied to the oscilloscope mainframe
(Power-On mode), the DF1 reference memory and the
memory which acquires data from the 7D01 are checked
for proper operation of the random access memory (RAM)
integrated circuits (refer to Error Message Displays in this
section). Then, the 7D01 is reset and the DF1 reference
memory and the 7D01 memory are cleared. The Display
Mode is automatically set to Timing Diagram, the LOGIC
is set to POS, and the cursor location (trigger-to-cursor
readout) is set to +0. All other DF1 push-button selections
are cancelled.
DISPLAY MODES
The DF1 displays digital data in 3 Display Modes: Timing
Diagram, Map, and State Table. Figure 2-3 shows the
controls required to activate typical DF1 displays.
Timing Diagram Displays
The front-panel TIMING DIAGRAM push button selects
the Timing Diagram display (4, 8, or 16 channels) from the
companion 7D01 Logic Analyzer (see Fig. 2-3). The cursor
function of the 7D01 provides an intensified zone on the
data display and a corresponding numerical readout display
shows the logic state for each displayed channel of data.
The position of the cursor, relative to the trigger, is also
displayed on the crt readout. Refer to the 7D01 manual for
more information on the 7D01 Logic Analyzer.
The source of the display readout can be from the oscillo-
scope mainframe readout system (MFR) or the DF1
(FOR R). (Refer to Internal Controls and Connectors, in
this section, for more information.) When the Timing
Diagram Display Mode is selected (Readout Source jumper
set to Formatter Readout) after either the HEX, OCTAL,
or BINARY State Table function has been displayed, the
cursor
word readout is displayed in the same base-number
system as displayed previously in the State Table Display
Mode. Then, the cursor word readout changes between
binary and the base-number system in the previously
selected State Table Display Mode, with every other push
of the TIMING DIAGRAM push button. However, if the
Readout Source jumper is set for mainframe readout
(MFR), cursor word readout is displayed only in the binary
system.
2-4
Map
The Map function provides a view of the 7D01 memory
displayed as x-y coordinate dots on the crt. The vertical
axis represents the most significant half of the data word
and the horizontal axis represents the least significant half
(see Figure 2-3).
The map display can be formatted from 4, 8, or 16
channels of input data. Therefore, 4- and 8-channel map
displays are plotted over the entire crt display area in the
same manner as a 16-channel display. A 16-channel display
is capable of 64,000 coordinate points, an 8-channel display
is capable of 256 coordinate points, and a 4-channel display
is capable of 16 coordinate points.
A map cursor, indicated by a plus symbol (+), sequences
automatically through the data locations in the order in
which the data was loaded into memory. The cursor scans
at a FAST or SLOW rate, as determined by the CURSOR
SCAN push buttons. When either the FAST or SLOW push
button is held in, the cursor scan is stopped near a desired
location on the display and can be positioned to the exact
location with the 7D01 cursor position controls. Also,
when the MANUAL CURSOR SCAN push button is
pressed, the 7D01 cursor position controls are used to
manually position the cursor to the exact position desired.
The readout display shows the logic state of the cursor
word (bottom of crt), and the position of the cursor point,
relative to the trigger point, is displayed at the top of the
ert.
The map display is particularly useful for a fast overall
check of digital systems. First of all, the map display
pattern for a particular set of digital inputs must be known.
Then, if there is a change in any one of the input signals,
the map display pattern will change. A different map
display pattern indicates that the circuits are not operating
in the normal manner. Figure 2-4 illustrates a map display
pattern from 16 signal inputs and shows that the map
display pattern changes when input signals are removed.
State Table Displays
The State Table function enables the data, recorded in the
7D01, to be displayed in a tabular format. The cursor word,
the sixteen words which follow, and the trigger word are

words of the state table, it is indicated by a blinking
condition. The position of the cursor, relative to the trigger,
is also displayed on the crt readout (see Figure 2-3).

Each time the 7D01 cursor position is changed or the 7D01 —
is reset, the display is updated. If the data ends before 17
words are displayed, the remainder of the display is filled
with an asterisk (*) character. Any “old data” from the
7D01 memory is indicated by an ‘’X”’ character.
Three push-button switches select State Table displays in .
HEX (hexidecimal, base 16), OCTAL (base 8), or BINARY
(base 2) codes. The digits are grouped in threes or fours
depending upon the setting of the 7D01 cursor byte switch.
7D01 ONLY. The State Table display from the 7D01 is
displayed on theleft side of the crt. The © INTENS REF
displays are not functional in the 7D01 ONLY mode.
7D01 © INTENS REF. Two state tables are displayed
simultaneously on the crt. The state table from the 7D01 is
displayed on the left half of the crt and a reference state
table is displayed on the right half of the crt (see Figure
2-3). When the 7D01 © INTENS REF is initially selected,
the STORE 7D01—>REF push button must be pressed to
load the reference memory. Any differences between the
7D01 and reference state tables are indicated by intensified
bits at the appropriate location in the 7D01 state table.
Any differences in the state tables due to old data, indeter-
minate data, end data, or blanked columns, is interpreted as
“don't care’ conditions and are not intensified in the 7D01
state table (refer to the Glossary in the General Information
section). If there are no differences between state tables,
the TABLES= indicator is illuminated.
REF TABLE FOLLOWS 7D01. The FOLLOWS 7D01
mode is functional only when operating in the 7D01 ®
INTENS
REF mode. The cursor location (trigger-to-cursor
readout) in the reference state table is aligned with the
cursor location of the 7D01 state table. As the 7D01
location is changed (by means of the 7D01 cursor position
or data position controls), the cursor location of the
reference state table follows.
REF TABLE HELD. The HELD mode is functional only
when operating in the 7D01 © INTENS REF mode. The
reference table cursor location remains at one setting,
allowing the cursor location in the 7D01 state table to be
moved independently (offset). Refer to Figure 2-5.
