vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
delay = a real output value, in seconds, indicating the arm delay. Valid return values: 0 s to 4294.967295 s

ESCRIPTION
This function queries and returns the arm delay for the EX1629. This indicates the amount of time, in seconds, that
the EX1629 will wait after receiving an ARM event before it transitions the trigger state machine from the ARM
layer into the TRIG layer. Note that the value this function returns may not be identical to the value set by the
vtex1629_set_arm_delay function, as the actual delay time will vary with the set sample frequency (i.e., there is
some inherent quantization of the value).
