11"x17' X-Y Analog Plotter-- VARIPLOTTER Series 1100E
VARIPLOTTER, Series 1100E is a self-balancing
potentiometer type recorder that plots one DC voltage
as a function of a second DC voltage. Flexibility of
design permits the 1100E to be used as an X-Y
recorder, or with the addition of accessory equip-
ment, as a function generator or as a unit to plot
digital information acquired from a _ keyboard,
punched cards, or punched paper tape.

Curves are plotted in a 10” x 15” area on 11” x 17”
graph paper. Parallax controls allow the setting of
the plot origin to any location on the plotting surface.
VACUUM HOLD DOWN —
Provides ease in aligning graph paper and holds it
firmly to the vinyl plotting surface.
DIFFERENTIAL INPUT —

function generator accessories for 1100E VARIPLOTTER-
FUNCTION GENERATOR MODEL 2.040
... permits use of 1100E VARIPLOTTER
as a curve follower to generate the function
of a variable.
This accessory consists of a kit containing all neces-
sary components and cables for generating the
function of one variable with the 1100E VARI-
PLOTTER. The dependent variable, f(x), is plotted
manually as a function of the independent variable,
x, on standard graph paper using a special conductive
ink. The independent variable is plotted as the
abscissa (arm) and the dependent variable as the
ordinate (pen). The graph paper is placed on the
plotter and the curve is excited with R-F signals
generated in a _ transistorized Curve Follower
Oscillator plugged into the VARIPLOTTER Data
Connector. The pen is replaced with a special
pick-up coil which follows the curve as the independ-
ent variable moves the arm across the plotting surface.
A DC voltage is available from the VARIPLOTTER
which is proportional to the value of the dependent
variable.
BI-VARIANT FUNCTION GENERATOR
.. converts 1100E VARIPLOTTER to a
function generator of two variables.
The BIVAR function generator is designed to give
instantaneous solutions of quantities which are a
function of two variables. With the BIVAR the
family of curves are manually plotted on a semi-
conductive plate using conductive ink. The independ-
ent variables X and Y are plotted as the abscissa
(arm) and ordinate (pen). Lines of equal values
of the dependent variable, z, are energized with DC
voltages scaled to represent the constant values of z.
A conductive probe mounted on the VARIPLOTTER
pen holder, which is positioned by the plotter pen
and arm servo’s according to the values of X and Y,
measures the voltage corresponding to the value of z.
The BIVAR accessory includes two conductive surface
plates, one pick-up probe, a voltage loading unit and
the necessary cables for connecting the system to the
VARIPLOTTER. Also included are extra probe
points, conducting ink, brushes, ruler, and a case
for small accessories.
ALSO...
TIME BASE GENERATOR
The 2.227 Time Base Generator
converts the 1100E VARIPLOT-
TER into a time base recorder.
Provides a voltage signal that
positions the arm (x axis) of
the VARIPLOTTER at a fixed
rate of arm displacement versus
time.
KEYBOARD DATAPLOTTER
The 2.223 Keyboard when used
with the 1100F VARIPLOT-
TER comprises the 3000 Series
DATAPLOTTER system. It per-
mits rapid graphical plotting of
digital data, either as inked
point plots or coded symbol point
plots with the Symbol Printer
accessory.
INPUT FILTERS .. . provide five selectable
20 db steps of low pass filtering.
Available for either single ended or
differential inputs.
POWER MODIFICATION .. . adapting the
1100E VARIPLOTTER to operate from
220 volt, 50-60 cycle power.
PAPER LOCATING PINS... . facilitate
rapid alignment of plotting paper.
SPRING LOADED PEN ... holds the
plotting pen to plotting surface on
inclined mounted VARIPLOTTERS or
for writing at top speeds.
NULL-SENSING CIRCUIT . . provides
electrical indication when the 1100E
VARIPLOTTER has reached null.
Required when 1100E is used with digital
input from keyboard, card and tape
readers, or from plotting multiplexed
analog sources.
11’x17' Digital Plotter--Series 3100 DATAPLOTTER System
. automatically converts data from
punched cards or punched paper tape
to graphic form.
The full potential usefulness of digital computer
calculations is seldom fully realized due to the
difficulty of interpreting extensive tabular data.
Because of the excessive cost of hand plotting, the
benefits of graphic displays of digital data are usually
sacrificed. Now, with the DATAPLOTTER 3100,
this lost dividend can be recovered.
The basic 3100 system plots data from
punched cards; it includes the following
components:
Model 1100E VARIPLOTTER
Type 99.144 Data Translator (with 13-key Keyboard)
Type 2.229 Null-Sensing Circuit
Model 1121 VARIPLOTTER Stand
Type 2.257 Cable Assembly
For plotting data from punched paper
tape, the punched paper input accessory
may be added. It includes:
Modified FRIDEN Model 2 Tape Reader
and
Type 2.258 Cable Assembly
This accessory may be added in the field.
TRANSISTORIZED CONVERSION CIRCUITS
Transistorized conversion circuits and relay storage
matrices are utilized to convert digitally coded point
data into DC voltages representing the KX and Y
coordinates of the point to be plotted. Conversion
circuits, control circuits, and storage matrices are
mounted on plug-in printed circuit cards. Power is
supplied by an integrally mounted transistorized
power supply which is powered independently of
the VARIPLOTTER.
ACCURACY AND SPEED OF PLOTTING —
The error in conversion can never be greater than
+ 1 count. Static accuracy of the 1100E VARI-
PLOTTER is 0.075% of full scale for the arm and
pen. Plotting speed is up to 80 inked point plots per
minute, depending upon type of input.
ORIGIN OFFSET —
The plotting surface of the 1100E VARIPLOTTER
is electronically divided into 1000 (0 to 999) parts.
Origin offset allows the origin of a plot to be moved
“off-the-board” by as much as 900 of the 1000 counts,
thus providing for non-zero plot origin.
CONTINUOUSLY VARIABLE SCALE FACTOR —
Full seale deflection of the VARIPLOTTER pen and
arm can be made equivalent to a maximum of 2000
counts (+1000). Coarse and fine scale factor controls
for both X and Y coordinates are incorporated to
permit the continuous adjustment of the plotter pen
and arm scale factors. With these controls a minimum
of 2000 and a maximum of 100 counts can be made
equal to any plotting surface displacement.
DIRECT READOUT OF MATRIX —
An indicator is located on the control panel of the
Data Translator which permits the direct readout,
in binary coded decimal form, of the information
stored in both the X and Y matrices.
INPUT CODES —
The Data Translator is designed to accept two stand-
ard codes; the binary coded decimal for punched
paper tape, and the decimal code for IBM punched
cards. On special order the system can be adapted to
receive punched card or paper tape inputs from any
computer or data source.
PAPER TAPE INPUT —
A modified Friden, Model 2, motorized tape reader
may be supplied as the input device for the 3100
DATAPLOTTER. The tape reader accepts a seven-
column width tape of which only four columns are
used. Special reading units may be provided on
special order.
IBM CARD INPUT —
The 3100 Dataplotter will accept inputs from modi-
fied IBM 518, 514, 517, 519, 528, 024, 026, and 526
card reading equipment. The standard IBM card of
80 columns and 12 rows is used.
KEYBOARD INPUT —
The Data Translator is supplied with a 18-key
keyboard for manually entering point data and the
setting of scale factors and origins (parallaxes).
DATA OUTPUT —
The Model 1100EF VARIPLOTTER accepts 11” x 17”
plotting paper with a maximum useable plotting sur-
face of 10” x 15”. Seale factor and parallax controls
allow the plotting of a graph on any portion of the
plotting surface, or more than one graph can be
plotted on a single sheet of paper.
SYMBOL PRINTING —
Symbol Printer, Type 2.222, is available as an
accessory for the 1100E VARIPLOTTER to permit
the plotting of point data as coded symbol point
plots.
