7. Graphs 1, 2, 4 and 5 do not reflect the effects
of trigger error. To place an upper bound on
the added effect of this error term, determine
the frequency error from the appropriate
graph and add a trigger error term as follows:
Time or digit arming
Frequency
error
x+
Frequency
or period
Gate time x Number of samples
4 x 2 x Trigger error
Automatic or external arming
