How to set the parameters of 3FSK
(1)
Press the
Mod
function key, then press the
Type
softkey, turn the
knob
to select
3FSK
, press the
OK
softkey.
(2)
Select carrier wave shape
:
The carrier wave can be
Sine
,
Square
,
Ramp
, or
Arbitrary
wave (except DC).
Press
,
,
, or
to select a desired carrier wave shap.
(3)
Set carrier wave parameters
:
Press
the wave shap key
of the selected carrier wave to display the waveform
and parameters of the carrier wave. You can change the parameters of the
carrier wave. Press
Mod
to return to the modulation mode interface.
(4)
Modulating wave source
:
3FSK uses internal modulation source, and the modulating wave is set as a
Square with 50% duty cycle.
(5)
Set 3FSK rate
:
Press the
FSK Rate
softkey to set the 3FSK rate. The rate at which the output
frequency shifts between the carrier frequency and the two hop frequencies is
determined by 3FSK rate (for internal source). The range is 2 mHz – 1 MHz.
(6)
Set hop frequencies
:
Press the
HopFreq1
and
HopFreq2
softkey to set the two hop frequencies.
