Switch
The
controls are outlined
in blocks,
left
and
right,
associated
with
the appropriate display.
The
right-hand blocks generally
deal
with function and
output
definition,
whereas
the left-hand
blocks
are
concerned
with frequency,
mode
and
terminal con-
figurations.
Front Panel
Keys
All user
commands
from
front
panel keys
are
executed through
main program
firmware.
A
Key
LED
lit
signifies that condi-
tions are valid for the selected operation, and
not
merely
that the
key
has
made
contact.
At any
time, the
instrument
status is
described
by
the
combina-
tion
of
LED
states,
display values
and
display messages.
Generally,
if
an
invalid condition
is
selected,
an
error
message
will
be
displayed
and
a buzzer
will sound,
the
command
is
ignored and
the
4708
remains
in
its
previous
state.
