2 MODULATION
The AE20125 is capable of frequency (Frequency Shift
Keying,
FSK
) and phase modulation (Phase Shift Keying,
PSK
). For the modulation source, an internal frequency can be
selected or the external input may be used. The
MODULATION
menu is used to adjust the modulation parameters.
2.1 MOD TYPE
Modulation type can be
FSK
(frequency) or
PSK
(phase).
2.2 FSK FREQ
Here you can select the frequency step used to change the
frequency when using
FSK
.
Example: output frequency is 650,000 Hz, FSK FREQ is
5,000 Hz, modulation alternates between 650,000 Hz and
655,000 Hz.
2.3 PSK PHASE
Here you can select the phase step used the change the phase
when using
PSK
. The adjustment range is 0.1° - 359.9°. The
normal output's phase is always considered as 0°.
