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