LEVel
LEVel
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
for
the Edge, State, and
Delay Trigger Modes.
The
LEVEL
query
returns the trigger
level
of
the
current trigger mode.
