The characters
in the learn string
correspond to each Generator function.
A description of
how
to interpret
the characters
in the learn string is given in
Figure
2-7.
Table
2-12
shows the
conversion
from the learn
string to the hexadecimal
character.

CLEAR
COMMANDS
The following
IEEE-488
clear commands are recognized
by the Generator:
“CB”
Clear IEEE-488
input buffer
“CE” Clear IEEE-488
rejected
entry error status
“CL” Clear
instrument
The
“CB” command
can be
used to clear the
Generator
output
buffer. The
output
buffer
should be cleared
at the
beginning
of any remote
program to
synchronize
data output.
The
output
buffer is also
cleared at
power-on with
the “CL”
clear Generator
command,
or
the
buffer
is cleared
by the SDC
and DCL clear
interface
messages.
The “CE”
command
can be used
to explicitly
clear
the error status.
The error
status
is also
cleared
when
it is interrogated
with
the “IR”
command,
or the
“CL” clear
Generator
command,
or the SDC
and DCL
clear.
The “CL”
command
is used to clear
the instrument
state.
The same
actions are
performed
with
the SDC
and DCL
clear interface
messages.
(In
addition, the input
buffer
is cleared
with the
clear
interface
messages.)
The following
IEEE-488
commands
are
performed with
the
clear
Generatorcommand:
“RC98,
ROl, CE,
CB, RMO,
TMO, EMO, VMO,
UMO, SM192,
SP08,
XFO,
DWO,
CT’TEOR).
If a Software
Compensation
Procedure
is in progress,
it is exited
immediately
and all
measured
data is discarded.

INTERFACE
MODE
COMMANDS
Interface
mode commands
are
used to
configure
the Generator
for
different
modes of
IEEE-488
interface
operation.
Since
the Generator
knows
when its
RF output
has settled,
it
can be configured
to
synchronize
itself with
the controller.
This
eliminates WAIT
statements
in
the program,
which
are normally
used
to allow time
for the
output of
the controlled
device to
settle.
Table
2-13
lists the
interface
mode
commands.
