The
entire
record
is
transferred into the
Generator before processing begins. In
this
example, processing begins
when
the record terminator
CR
is
received.
The
following
character
(LF
in this
case)
will
not be
received into the
Generator
until
the entire record
is
processed
and
the
output has
settled.
No
wait statement
is
needed between
setting
up
the
Generator
and
taking the
measurement
because the
Generator
will
not
handshake the
LF
character
until
its
output has
settled.
NOTE
A
record
is
a
string of
characters separated by (EOR>.
A
message
is
the
smallest
group of
characters that the
Generator can process
when programmed
from
the
IEEE-488
interface.
NOTE
The output
valid state of the
Generator occurs 45
ms
after
any hardware has
been changed.

INTERROGATE
COMMANDS
Interrogate
commands
allow
the status
of
the
Generator
to
be given over
the
IEEE-488
interface.
These
commands
consist
of headers
only.
The
interrogate
commands
available
on
the
IEEE^88
interface
are:
"ID" Give Instrument
ID
"IE" Elapsed
Time
Indicator
"II" Interface
Mode
Status
"lO" Option Loading
'TR" IEEE-488 Rejected Entry Status
"IT"
Self-Test Results
"lU"
UNCAL
(uncalibrated) Status
"IV" Software
Revision Level
When
the
"ID"
command
is sent,
the
Generator responds with
its
instrument
model
number
(and end
of record character) as in
"6060B"<EOR>
.
When
the
"IE"
command
is
sent,
the
Generator responds with the time the instrument
has
been
in
operation
since
it
was
manufactured.
The
time
is
9
digits,
a decimal point,
a
lOth digit
and
the
<EOR>
character.
The
time
is
in
.1
hour
units.
For example,
"000003459.3"<EOR> indicates 3459.3
hours
of operation since
manufacture.
The
"II"
command
interrogates the current selection of
interface
modes.
A
5-digit
integer
followed
by
the
(EOR>
character
is
the
sum
of the
modes
selected as follows:
Terminator
