HP 54501A - Ter

TER
TER
(Trigger Event Register)
query
The TER
query
allows
the
Trigger
Event
Register
to
be
read.
When
the
Trigger
Event
Register
is
read
it
is
cleared.
A
one
indicates
a trigger
has
occurred.
A
zero
indicates
a trigger
has
not
occurred.
If
a trigger
event
is
not
found
and
the
sweep
is
auto-triggering
this
bit will
not
be
set.
A
Service
Request
(SRQ)
can
only
be
generated
when
the
bit
transitions
from
0
to
1,
therefore
the
bit
must
be
cleared each time
you
would
like
a
new
Service
Request
to
be
generated.
