LF Out
Trigger Key
This softkey is one of the choices in the LF Output Sweep Trigger menu. With
Trigger Key selected, when you press the Trigger front panel key you immediately
trigger a single sweep of swept-sine low frequency output.
The
Trigger key has autorepeat capability. Hold it down and you will repeatedly
trigger sweeps until you release the key.
Softkey Location: Press
LF Out, LF Out Source, Function Generator,
LF Out Waveform, Swept-Sine, LF Output Sweep Trigger, Trigger Key
Status after Normal Preset: LF output sweep trigger is set to Immediate
SCPI Commands:

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 low frequency
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 AM, FM, and
ΦM 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.
This softkey is only active when you have selected the internal source to operate
as a function generator.
Softkey Location: Press

LF Out Waveform, Swept-Sine, Trigger Out Polarity Neg Pos
Status after Normal Preset: Pos
