alues
The
bus
measurement
value
is
displayed
with
a
unit
\U".
The
DC
bus
measurement's
\1
U"
is
equivalent
to
\1
V".
The
displayed
value
in
the
DC
bus
measurement
does
not
corresponding
to
the
measured
voltage
because
the
voltage
detected
at
the
DC
bus
node
is
scaled
appropriately
and
measured.
The
scaling
factor
depends
on
each
DC
node
.
F
or
example
,
the
scaling
factor
at
the
DC
bus
node
1
of
+5
V
(A
UX)
is
approximately
0.405.
Therefore
,
the
displayed
value
is
nominally
2.025
U
(5
U
x
0.405).
A
typical
value
for
each
DC
bus
node
measurement
is
provided
in
the
DC
Bus
Node
Descriptions.
The
frequency
bus
measurement's
\1
U"
is
equivalent
to
\1
MHz".
F
or
example
,
a
measured
value
of
1
kHz
is
displayed
as
1
mU
.
A
typical
value
for
each
frequency
bus
measurement
is
provided
in
the
Frequency
Bus
Node
Descriptions.
