For
the
meaning
of
the
individual
bits,
see
to
the
sections
“The
QUEStionable:POWer:OVERRange
Node”,
“The
QUEStionable:POWer:LCURRent
Node”,
“The
QUEStionable:POWer:nCURRent
Node”,
“The
QUEStionable:POWer:LMONitor
Node",
“The
QUEStionable:POWer:HMONitor
Node”,
and
“The
QUEStionable:POWer:ENVTfemp
Node”.
A

means
that
there
is

Bit
3
of
the
QUEStionable:ISUMmary:INvSTrument
node
summarizes
this
node.
The
Source
Status
The
source
status
is
that
part
of
the
status
structure
that
shows
the
operation
of
any
source
modules
in
the
instrument.
The
node
is
sixteen
bits
wide.
Only
15
of
these
bits
are
used.
The
node
has
it’s
own
condition,
event
and
enable
registers,
and
it’s
own
transition
filters.
These
registers
and
filters
are
described
earlier
in
this
chapter.

The
Source
Register
The
Source
Status
Commands
The
following
are
the
source
status
commands
and
queries.
These
commands
and
queries
are
available,
without
regard
to
the
configuration
of
the
instrument,
even
when
there
are
no
sources
installed.
In
this
case
you
can
read
the
registers,
but
they
always
return
a
0.
