Hardkey and Softkey Reference
Phase Modulation
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 swept-sine phase
modulation.
This softkey is coupled to the
Trigger In Polarity Neg Pos softkey for swept-sine
AM, FM, and LF Out, and to the
Ext Neg and Ext Pos sweep trigger selections in
the Sweep/List Menu. If you set the
Trigger In Polarity Neg Pos softkey in the ΦM
Swept-Sine Menu to
Neg, the Trigger In Polarity Neg Pos softkey is also set to Neg
for swept-sine AM, FM, and LF Out. And, in addition, if the step or list sweep
trigger is set to
Ext Pos, the trigger selection will automatically be changed to
Ext Neg. The same softkeys will toggle to Pos or to Ext Pos if you select Pos in the
Swept-Sine
ΦM Menu.
Conversely, if the
Trigger In Slope Neg Pos softkey is toggled in the swept-sine
AM, FM, or LF Out menus, it will cause the swept-sine
ΦM softkey to toggle
also. This is also true for the
Ext Neg and Ext Pos step or list sweep trigger
selections.
Softkey Location: Press
FM/ΦM hardkey, toggle FM/ΦM softkey to ΦM, press
