Starting point of gate B

The start of the gate B (function B-start) is normally po-
sitioned starting from the initial pulse as in the case of
gate A.
You can alternatively specify the start of the gate B in re-
lation to an event in gate A. This function is also referred
to as automatic gate tracking.
If there is no event in the gate A, the starting point of the
gate B is identical with the value of the function A-start.

Setting the gates (function groups GATE A and GATE B)
– Switch to the second operating level.
– In the function group CONFIG2, select the function
B START MODE.
– Select the required setting.
If you choose the setting A, the gate B is afterwards al-
ways shifted automatically when you shift the starting
point of the gate A.
The width and the threshold of the gate B are not affect-
ed by the gate tracking.
The tracking of the optional gate C is identical with that
of the gate B. However, the gate C can additionally still
be coupled to events in the gate B.
