"""Prepare PQSC for triggering the instruments.
This method configures the execution engine of the PQSC and
clears the register bank. Optionally, the *number of triggers*
and *hold-off time* can be set when specified as keyword
arguments. If they are not specified, they are not changed.
Note that the PQSC is disabled at the end of the hold-off time
after sending out the last trigger. Therefore, the hold-off time
should be long enough such that the PQSC is still enabled when
the feedback arrives. Otherwise, the feedback cannot be processed.
Args:
deep: A flag that specifies if a synchronization
should be performed between the device and the data
server after stopping the PQSC and clearing the
register bank (default: True).
repetitions: If specified, the number of triggers sent
over ZSync ports will be set (default: None).
holdoff: If specified, the time between repeated
triggers sent over ZSync ports will be set. It has a
minimum value and a granularity of 100 ns
(default: None).
