LO
resulting
in
a differential (float-
ing) switching configuration.
For remote sensing,
all
three
triax
connectors
on
the
Source Measure
Unit
must
be
used. Thus, three switch-
ing
cards
would
be
required for a test configuration
using
2-22
+
remote sensing.
An
example test configuration using re-
mote
sensing
is
shown
in
Figure
2-19.
Switching
SENSE
LO
and
OUTPUT LO does
not
require
low
leakage paths.
Thus, a general
purpose
switching card (Model7056) can
be
used.
This
test configuration will test
10 OUTs.
How-
ever, for clarity, only
one
OUT
is
shown
connected to the
switching cards.
