A
program
might look
something like:
PRINT @1.
"CL, TMl. RMl,
VMl, UMl " !
PRINT ei,
"FRIQOMZ,
AP-25DB”
!
PRINT @2.
"?”
!
INPUT @2,
"R*"

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
it is
programmed
from
the IEEE-488
Interface.
NOTE
The output

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-488
interface are:
“lA”
Attenuator
Actuation Log
“ID”
Instrument
ID
“IE”
Elapsed Time
Indicator
“H”
Interface Mode

“IL”

UNCAL and
Self-Test
Error Log
“lO”

“IR” IEEE-488

“lU”

Memory
Checksum
Status
The “lA”
command
interrogates
the attenuator
actuation
log. Each
time an
attenuator pad
is
removed from the
RF
path, the
corresponding
counter in
non-volatile
memory is
incremented.
This
means that if
an
attenuator pad is
removed
then inserted,
the count
will only
increment
once. The
Generator
responds to
the “I A”
command
with seven
counts (one
for each pad).
The
counts are
separated by
commas,
and the
response is
terminated
with the
end of
record
character
(<EOR>).
