1.  Internal trigger latency is defined as the delay between the applied RF crossing the trigger level and the U2021XA/22XA switching into the triggered state.
2.  External trigger latency is defined as the delay between the applied trigger crossing the trigger level and the U2021XA/22XA switching into the triggered state.
3.  External trigger output latency is defined as the delay between the U2021XA/22XA entering the triggered state and the output signal switching.
