[1] May generate pulses below 1ns but pulse width accuracy is not specified.
[2] Assumes that trigger used in divide by 1 mode. Other divide modes are not specified.
[3] Pulse skew measured from 30% of trigger signal amplitude to 30% of pulse range amplitude.
[4] Uncertainty specification applies only for pulse periods that are 3 µs or greater in duration.
Otherwise, skew uncertainty is typical.
