Sweep/List
Trigger In Polarity Neg Pos
Press this softkey to toggle between a negative TTL level trigger (0 V) and a
positive TTL level trigger (+5 V) for externally triggering step or list sweeps.
The
Pos (and Neg) selections for the Trigger In Polarity softkey in the
Sweep Trigger and Point Trigger menus are coupled; you cannot choose
Neg for
one and
Pos for the other. The first selection will follow the second. For example,
if you choose
Neg for the sweep trigger and then choose Pos for the point trigger,
the sweep trigger selection will automatically change to
Pos.
If either the sweep trigger or the point trigger is external, the polarity is coupled to
the
Trigger In Polarity Neg Pos softkey for swept-sine AM, FM, ΦM, and LF Out.
For example, if you set the sweep trigger to
Pos, the Trigger In Polarity Neg Pos
softkey will toggle to
Pos for swept-sine AM, FM, ΦM, and LF Out. Conversely,
if the
Trigger In Slope Neg Pos softkey is toggled in the swept-sine AM, FM, ΦM,
or LF Out menus, it will cause the sweep or point trigger softkeys to toggle also.
