+When `Rhs2116StimulusTrigger` receives a double, a stimulus is triggered. The value of the double
+determines the duration of a precise hardware delay between triggering and actually delivering the
+stimulus. If the double is zero, there is no hardware delay. The stimulus waveform delivered is
+configured in the [Headstage RHS2116 GUI](xref:rhs2116_gui). If the sequencer is busy or the
+stimulator is disarmed when the trigger occurs, stimulus won't be delivered. This can be checked
