1.2 OPERATION OVERVIEW
The fundamental models for the
Source
Measure
Units
are shown
in
Figure 1-1. When programmed to source
voltage, the
!METER
is connected
in
series
with
the
V
soURCE
and
output. When programmed to source current, the
VMETER
is connected across
(in
parallel to) the
!soURCE
and
output.

V soURCE -
The Models 236
and
238 can source from
±lOOJl
V
to
±llOV. The Model237 has
an
additional source
range of
±llOOV.
The programmable current compliance
is
up
to
lOOmA
for the Model236,
lOOmA
for the 237 (ex-
cept
lOrnA
on
the
llOOV
source range),
and
lA
for the
Model238 (except
lOOmA
on
the
llOV
source range).
