If
the
corresponding
bit
of
the
service
request
enable
register
is
\1",
the
service
request
(SRQ)
is
generated
with
the
positive
transition
of
the
status
byte
register
bit.
By
generating
the
SRQ,
you
can
notify
the
controller
that
the
analyzer
is
requesting
service
.
Event
Register
Reects
the
correspondent
analyzer
condition
as
a
bit
status
.
These
bits
monitor
the
changing
analyzer
state
continuously
and
change
the
bit
status
as
required.
Y
ou
cannot
change
bit
status
by
GPIB
command.
The
analyzer
has
the
following
event
registers:
Instrument
Event
Status
Register
.
Standard
Event
Status
Register
.
Operation
Status
Event
Register
.
Enable
Register
The
enable
register
selects
which
event
register
bits
can
set
the
bit
in
the
summary
bit
of
the
status
byte
register
that
is
connected
to
SRQ
generation.
The
register
bits
work
like
mask
bits
.
When
you
want
to
set
a
bit
in
the
status
byte
register
by
a
specic
register
condition,
set
the
corresponding
enable
register
to
1.
This
sets
a
1
bit
in
the
status
byte
register
with
a
corresponding
event
register
bit.
Use
this
register
to
select
which
event
register
bits
generate
the
SRQ.
All
event
registers
have
a
corresponding
enable
register
for
each
bit.
Status
Byte
Register
If
enabled
event
register
is
set
to
1,
the
corresponding
bit
of
the
status
byte
register
is
set
to
1.
This
register
also
indicates
the
output
queue
and
SRQ
status
.
The
value
of
the
status
byte
register
can
be
read
by
using
the
SPOLL
statement
or
the
*STB?
query
from
the
controller
.
SPOLL
reads
the
status
byte
register
value
directly
without
the
analyzer
being
set
to
remote
.
Therefore
,
you
can
continue
to
operate
front
panel
keys
while
a
controller
is
reading
the
status
byte
register
.
On
the
other
hand,
the
*STB?
query
sets
the
analyzer
to
remote
mode
.
Reading
the
status
byte
register
by
either
command
does
not
aect
the
contents
of
the
status
byte
register
,
except
that
SPOLL
clears
the
RQS
bit.
A
serial
poll
initiated
by
using
the
SPOLL
command
reads
bit
6
of
the
status
byte
register
as
the
RQS
bit.
The
*STB?
command
reads
bit
6
as
the
MSS
bit.
SRQ
(Service
Request)
can
be
generated
by
the
status
byte
register
by
setting
the
service
request
enable
register
.
