The function of the

this
command are rounded to the nearest

ns.
In
the Pattern Trigger Mode
the valid arguments
for
the
CONDITION
command are
ENTER,
EXIT,
GT, LT, RANGE.
In the Pattern Trigger Mode the
CONDITION
command
is
used to
specify
if the trigger will be generated upon entry to the specified logic
pattern, upon exiting the specified logic pattern, or if the pattern must be
present for
a
specified amount of time. The time
in the
pattern trigger
mode
can be
specified to be greater than
a
value
(GT), less
then
a

or between two values
(RANGE).
These are the same settings that are specified using

In the
TV
Trigger Mode
the

the
range
of time values for the trigger to occur.
This command is only valid
