HP 54501A - The State Trigger Mode

The
State
Trigger
Mode
When
the
State
Trigger
Mode
is
selected
the TRIGGER:SOURCE
command
is
used
to
select the
clock

The
syntax
for
selecting
the
clock
source
is
TRIGGER:SOURCE
CHANNEL!
After
the
clock
source
is
selected,
the
correct
edge
for
the
clock

be
selected
using
the TRIGGER:SLOPE
command
which
can
be
set
to
NEGATIVE
or
POSITIVE.
Next
the
TRIGGER:PATH
command
can
be
used
with the
TRIGGER:LOGIC
command
to
set
the
three
bit logic
pattern
to
qualify
the
clock
trigger.
These
commands
could
be
sent
using
the
following
syntax
":TRIGGER:PATH
CHAN2;:TRIGGER:LOGIC
LOW,
or
":TRIGGER:PATH CHAN2;
LOGIC
LOW".
The
TRIGGER:CONDITION
command
in the State
Trigger
Mode
will
set
the
"is/is
not
present"
state
using
the
parameters
TRUE for
"is
present"
and

for
"is
not
present."
In
