2. For the purposes of 3A002.c.4.b.1., probability of discovery is also referred to as probability of intercept or probability of capture.
3. For the purposes of 3A002.c.4.b.1., the duration for 100 % probability of discovery is equivalent to the minimum signal duration necessary for the specified level measurement uncertainty.

For the purposes of 3A002.c.4.b.2., a 'frequency mask trigger' is a mechanism where the trigger function is able to select a frequency range to be triggered on as a subset of the acquisition bandwidth while ignoring other signals that may also be present within the same acquisition bandwidth. A 'frequency mask trigger' may contain more than one independent set of limits.

For the purposes of 3A002.h.:
1. A resolution of n bit corresponds to a quantisation of 2n levels.
