Running warmup pointsΒΆ
A set of warmup points can be run on the core device before a scan starts allowing equipment up to be brought up to a desired operating temperature before it is used to perform measurements in the scan.
The default behavior of a scan is to execute the measure(point)
interface method self.nwarmup_points
number of times for each registered measurement with the point
argument set to 0.0
.
self.warming_up
is set to True
immediately before warmup points are execute and is set to False
immediately after all warmup points have executed. This allows determining when to run warmup points within the
measure method.
def measure(self, point):
if self.warming_up:
# ... execute commands for warming up devices
# e.g. set dds frequency and turn on TTL
else:
# ... execute commands for the measurement
If the warmup()
interface method is implemented
warmup(point)
will be executed instead of
measure(point)
. This allows warmup and measurement commands
to be separated and also results in faster execution of the measure()
method since it does not need to check
self.warming_up
each time it is called during the execution of the scan.
def warmup(self, point):
# ... execute commands for warming up devices
# e.g. set dds frequency and turn on TTL
def measure(self, point):
# ... execute commands for the measurement
Additionally, if the get_warmup_points()
interface method
is implemented the returned set of points will be iterated over and the point
argument of either
measure(point)
or warmup(point)
will be set to the current warmup point.
