Trigger Key
This softkey is one of the choices in the AM Sweep Trigger menu. With
Trigger Key selected, when you press the Trigger front panel key you
immediately trigger a single sweep of swept-sine amplitude
modulation.
The
Trigger key has autorepeat capability. Hold it down and you will
repeatedly trigger sweeps until you release the key.

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,
Φ
M, 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.
Default Value: Pos
