Ter - HP 54501A Programming Reference Manual

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.
