command/query
The
:TRIGGER:LEVEL
command
sets the
trigger
level
voltage
of
the
active
trigger. This
command
can
be
sent
in
any
mode,
however
only
two
separate
levels
are
stored. One
value
is
kept
for
the
TV
Trigger
Mode
and
another value
is
kept
for
all
other
modes.
If
you are
in
the
Pattern
Trigger
Mode and set
a trigger
level
value,
that
level
will
also be used

Delay
Trigger
Modes.
The
LEVEL
query returns
the
trigger
level of
the
current
trigger
mode.
