4. BASIC OPERATION
4.7.2 Screen for modulation setting and manipulation
This subsection describes the screen configuration used in common for the modulated oscillation
mode.
The settings and manipulations are done on the Oscillator setting screen. The Oscillator setting screen
is displayed as “Oscillator” in the top left part of the screen. When another screen is displayed, press
the
MENU
MENU key to display the top menu, then select [Oscillator] and press the

key.
a) Setting the oscillation mode to modulations
1.
Set [Mode] (oscillation mode) to
[Modula-tion] on the Oscillator setting
screen. The oscillation mode is
switched to modulation as a result.
In the modulated oscillation mode, the
setting screen consists of two pages,
which can be toggled with the
NEXT
NEXT key.
b) 1st page of setting screen: Screen for setting the carrier signal
