5100
Series
1-11.
Modification of the output to measure the
devia-
deviation
in
a
percent of error figure is displayed for
each
change
of the
output
from the base. The frequency
may
be altered
for AC
outputs
to cover a range of fre-
quencies;
however, there
is
no percent of error display.
The
modifications can be programmed from either the
Front
Panel or a Remote Source.
1-12.
Storage System Models
1-13.
The storage
system consists
of
a storage
memory
and a mini-cassette tape system. The storage
memory
holds up to 61 separate fixed length instructions. Any
field not filled
when
an instruction is created is filled with
the default condition; i.e., either the allowable maximum
or minimum,
as is applicable. Data stored in the memory
to form a test program for an instrument, or instruments,
may be read
out
as desired or transferred, through the use
of the
integral
tape
system,
to a tape for a
permanent
record.
The
storage
memory may be loaded from a pre-
recorded
tape
through
the
tape
system to
perform a
standard
calibration
procedure.
A
program must be
loaded
into
the storage
memory to
be run, the instrument
is
not able
to
operate directly
from
the prerecorded
tape.
A
printed
listing
of
the
program
or the
data from
the
step
in progress
can
be obtained from storage system models
equipped with an
optional Remote Interface and an ex-
ternal printer.
1-14.
Element
Resistive
Models
1-15.
The
environmental element-resistive
case is a
fiberglass shell with
removable front and rear covers.
The case has
handles
to provide ease of transportation
and
seals on the
case
openings to resist entrance of the
elements
when
the case is closed. The covers must be
removed
to operate the system. The only change in inter-
nal
circuitry
is
the substitution of all position relays so
that the
instrument
can be operated while sitting at any
angle.
Operation
of the instrument is identical with the
standard instrument.

OPTIONS
1-17.
Analog
Options
1-18.
The
Wideband Option
(-03)
allows outputs
of
300
gV
(-57.5
dBm)
to
3.1623V
rms
(4-23
dBm) at
fre-
quencies from 10
Hz to
10
MHz
into a
load impedance of
50 ohms. The output impedance
is 50
ohms and
50
ohm
coaxial cable should be
used to transfer the output
signal.
1-19.
interface Options
1-20.
Two system interface options
are available for
the 5100 Series. Option
-05
interfaces
the instrument to
the IEEE
488-1975
Bus
System.
Option
-06
interfaces the
instrument to a system
using
a
RS232
interface. Only one
of the interface options can be
installed
at a time; how-
ever, they are easily exchanged with a
minimum
of opera-
tor training and time.

Summarized
Specifications
1-23,
Table l-l summarizes the 5100 Series accuracy
specifications when they are used in a typical meter cali-
bration
service. The tolerances
in
the table are valid
provided the ambient
temperature is between 20
degrees
and 30
degrees Celsius,
the
relative
humidity is less than
85%
and
the
input line
voltage is within
10%
of nominal.
In addition,
they
are
applicable
only
when the instrument
being calibrated is an analog
voltmeter
with more than
1000 ohms/ volt sensitivities, a
TVM
or DVM with great-
er than 1 Megohm input impedance
or analog
or digital
ammeter with less than 1 volt total
voltage
drop.
