Program
string characteristics
If
more than 25 bytes
have been
programmed
before
receipt
of
any terminator the
execution of the
string
will
commence
sequentially until sufficient
space
is
available for further input data.
If
an invalid
command
is
sent
an
SRQ
will
be
generated, the associated status byte containing a
syntax or option
error.
In this
case the
output
available
is
'ICrLf
NOTE:
1.
For program instruction requiring
only one
numeral
after
an
alpha
character,
the
last
numeral
is
operated
on and
a syntax
error
reported.
e.g.
F123
results in
F3 (DCV).
2.
For
all
program
strings a finite
time
is
required for execution, e.g.
the
string
"R4F3Q1T7="
will
be
processed
and
triggers
enabled
after
approx
15mS
from
receipt
of
string
terminator.
Bus
Remote.
The
DVM
will
go
into
remote
when
remote enable
line
(REN)
is
true
and the device
receives
its
listen
address.
It is
possible to
send
a
program
string to the
DVM
when
in local
which
will
be acted
upon immediately
when
the
DVM
goes
to
remote.
Local. The
GTL
message returns the
DVM
to
front
panel control in
the condition
in
which
it
was
last
programmed remotely with
the
exception of the
trigger
mode
which
is
forced to
T5
and superfast
which
is
cancelled.
Clear.
When
the
instrument receives
a
clear
message
(SDC
or
DCL)
it
will
revert to
a
predetermined
state
of
DC
volts
1000V range
and
hold.
