frequency at a limited duty cycle and cutoff any length of burst after that
length of time). The software will not check to check timing constraints in
this mode, meaning that if the timing if violated, the output may be
erroneous and not predictable (only while the constraints are violated – for
example if the number of bursts exceeds the time period of the packet
frequency this would violate the hardware of the unit). Violating the timing
can be a number of things such as a burst frequency larger than the
packet frequency, more pulses/delays than allowed in a single packet so
that timing overlaps, etc. The timing constraints are left up to the user’s
configurations so that the unit may be used to it’s full potential, however
the user may want to output a signal that does not violate any timing
constraints to receive a correct burst and frequency.

Single Shot Mode
In this mode, the pulse widths and the pulse delays can be set to their
maximum values without any timing constraints. After the OUTPUT button
is depressed, OUT1 and OUT2 will generate a single pulse according to
the individual channel settings.
