Setting
This control is dependent on the Frequency Input Type setting in
Setup. When set to PRESET, the UP/DOWN Arrow keys will
cycle through the three preset channels (108.000, 108.050,
117.950. You can click in the center of the control to pull up a
popup window for selection. When set to CHANNEL, the
UP/DOWN Arrow keys will increment, or decrement values
based on the selected CHAN STEP SIZE. CHAN STEP SIZE is
selected by clicking in the center of the control. Selections
include .05/.15 MHz and .5/1 MHz. When set to VAR, the
UP/DOWN Arrow keys will increment, or decrement values
based on FREQ STEP SIZE. FREQ STEP SIZE is selected by
clicking in the center of the control. Selections include 0.001
MHz, 0.010 MHz, 0.100 MHz, and 1.000 MHz. Allowable Range
is from 107.0 MHz to 118.0 MHz.
The UP/DOWN Arrow keys will increment, or decrement values
based on POWER STEP SIZE. POWER STEP SIZE is
selected by clicking in thecenter of the control. Selections
include 0.05 dB, 1.0 dB, and 10.0 dB. Range is from –67.0 to
13.0 dBm.
This field depends on the setting of BEARING STEP. If BEARING
STEP is FIXED, the UP/DOWN Arrow keys will update the value
in 30-degree increments. Clicking in the center of the control will
allow direct selection of a Bearing value from 0 to 330 degrees.
If BEARING STEP is VARIABLE, the UP/DOWN Arrow keys will
update the
value in degree increments based on BEARING STEP SIZE.
BEARING
STEP SIZE is selected by clicking in the center of the control.
Values can
be 0.1, 1.0, 10.0, and 100.0. Range is from 0.0 to 360.0
degrees.

Clicking in the center of this control opens a window with slider
controls to allow adjustment of the Master Modulation Depth in
2% offsets from 0 to 110%. The Master Modulation control
functions as a multiplier of the individual modulation
components. The Master Modulation Depth is the sum of the
Depths of Modulation (SDM) of the individual tone components.
This field allows the 30 Hz Reference, 30 Hz Variable, or both to
be deleted. Press anywhere on this control for the popup
selection window.
