- Parameters:
driver (
TetrammDriver
)
Methods
arm
()disarm
()get_deadtime
(exposure)prepare
(trigger_info)set_exposure
(exposure)Set the exposure time and acquire period.
Start acquiring driver, raising ValueError if the detector is in a bad state.
wait_for_idle
()- async set_exposure(exposure: float) None [source]#
Set the exposure time and acquire period.
As during the exposure time, the device must collect an integer number of readings, in the case where the exposure is not a multiple of the base sample rate, it will be lowered to the prior multiple ot ensure triggers are not missed.
- Parameters:
exposure (How long to wait for the exposure time and acquire period to be set.) – Desired exposure time.
- Return type:
- async start_acquiring_driver_and_ensure_status() AsyncStatus [source]#
Start acquiring driver, raising ValueError if the detector is in a bad state.
This sets driver.acquire to True, and waits for it to be True up to a timeout. Then, it checks that the DetectorState PV is in DEFAULT_GOOD_STATES, and otherwise raises a ValueError.
- Returns AsyncStatus:
An AsyncStatus that can be awaited to set driver.acquire to True and perform subsequent raising (if applicable) due to detector state.
- Return type:
AsyncStatus
