OPTIONAL AND
SPECIAL
FEATURES
Option
02:
4-Iine
BCD
l-2-4-8,
"1"
state
posi-
tive in lieu of L-2-2-4
(identical in other
re-
spects
to
above
Output
data) for
digits
only.
Option 03: 4-Iine BCD L-2-4-8, "1" state
nega-
tive in lieu of
t-2-2-4
(identical in other
re-
spects
to
above
Output
data) for
digits
only.
Remote
Operation: AII
functions
which may
be
programmed
from
the front panel
controls
(in normal use) may
be
programmed from
a
remote location except
for
the
"Sample Rate"
(as
defined above)
and
the sensitivity control
setting.
The instrument provides
(through
rear
panel
connectors)all voltages necessary
for
remote
control.
The
programming volt-
ages
for Time
Base and Function
control are
Iow
level,
-15
volts
dc
at
5
ma
per gate.
Con-
trol
may
also
be
achieved
by
using an
external
-15 volt dc
supply.
The
position of the deci-
mal point andmeasurements unit maybecor-
rectly
illuminated from the remote
location,
using +1?0
volts dc from the internal or
an
external
supply.
