Reading
Out
Measured Result
The
program of
Figure 4-7
is
detailed
below
.
Lines
50 to
60
Sets
the
GPIB
address
.
Line
70 Sets
the
data
transfer
format
to
the
binary
format.
Lines
90 to
100
Turns
ON
the
trigger
system
continuous
startup
and
sets
the
trigger mode
to
the
external trigger
.
Lines
120 to
130
Reads
out
the
ON/OFF
state
of
the
comparator
function
and
assigns it
to the
Comp ag
variable
.
Lines
170
to
210
Makes
the
setup
generate
an
SRQ
when
measurement
nishes
and
clears the
status
byte
register
and
operation
status
event
register
.
Lines
250
to
260
Sets
the
branch
destination
of
the
SRQ
interrupt
and
enables
the SRQ
interrupt.
Lines
270
to
280
Displays
the
message
to
prompt
the
user to
input an
external trigger
and
then
waits
until
the
external
trigger
is
inputted
and
the
measurement
nishes
.
Line
300
Executes
the
measured
result
readout
command
(
:FETC?
).
Lines
310
to
340
Reads
out
the
header
part.
Line
360
If
the
Comp
ag
value
is
1
(the
comparator
function
is
ON),
reads
out the
measurement
status
measured
parameter
result
and
comparator
sorting
result.
Note
Binary
data
must
be
read out
without formatting.
Therefore,
use
an
I/O
path
(@Binary) set
up as
such
for
readout.
This
is
also
applicable
to
Line
380.
Line
380
If the
Comp
ag
value
is not
1
(the
comparator
function
is
OFF),
reads
out
the
measurement
status and
measured
parameter
result.
Line
400
Reads
out the
message
terminator
at
the
end
of
the
data.
Lines
440
to
450
Displays
the
measurement
status
and
measured
primary
parameter
result.
Line
470
If
the
Comp
ag
value
is
1
(the
comparator
function
is
ON),
displays
the
comparator
sorting
result.
Line
490
If
the
Comp
ag
value
is
not
1
(the
comparator
function
is
OFF),
displays
\Comparator
