Setting the Modulation Frequency
Application
In the case of amplitude modulation, the output signal envelope changes as a
function of the frequency and amplitude of the modulation signal.
Setting the
AM frequency
1.
In the
submenu
press the
function key
.
The entry field for entering the frequency is displayed together with the
currently applicable setting. The default setting is "100 Hz".
2.
Enter a new value ( 5-55).
The permissible entry range is:
10 mHz
≤
Frequency
≤
100 kHz
in 10 µHz steps
The new setting is stored and then displayed in the parameter field if
modulation is switched on ( 6-117).
Setting the Modulation Depth
Application
The AM modulation depth m describes the ratio of the maximum to the
minimum amplitude A of the modulated signal.
