See also, “I/Q Modulation” on page 190.
18. Knob
Rotating the knob increases or decreases a numeric value, or moves the highlight to the next digit,
character, or item in a list. See also, “Front Panel Knob Resolution” on page 28.
19. Incr Set
This hardkey enables you to set the increment value of the currently active function. The increment
value also affects how much each turn of the knob changes an active function’s value, according to
the knob’s current ratio setting (see “Front Panel Knob Resolution” on page 28).

This switch selects the standby mode or the power on mode. In the standby position, the yellow LED
lights and all signal generator functions deactivate. The signal generator remains connected to the
line power, and some power is consumed by some internal circuits. In the on position, the green LED
lights and the signal generator functions activate.
