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 canprocess whenprogrammed
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
mode= 1
Record mode
=
2
Valid mode
=
4
Unbuffered mode= 8
Error
Mode
=
16
