Trigger Out Polarity Neg Pos
This softkey toggles the polarity of the TTL signal that is output at the rear panel
TRIGGER OUT connector. When
Trigger Out Polarity Neg Pos is set to Pos, the
output signal is asserted high (+5 V) at the start of the swept-sine amplitude
modulation sweep and low (0 V) when the sweep is concluded. Setting
Trigger Out Polarity Neg Pos to Neg reverses the polarity, where a high is 0 V and a
low is +5 V.
This softkey is coupled to the
Trigger Out Polarity Neg Pos softkey in the
swept-sine FM,
ΦM, and LF Out menus and the sweep/list menu. When the
polarity is toggled for this softkey in any one of these menus, it affects all
locations of the softkey.
