Set Hopping Frequency
When FSK mode is enabled, the default hopping frequency is 10 kHz. It can be change by multifunction rotary
knob and arrow keys or press soft key
HopFreq
,
and then use numerical keyboard to input number and select
unit soft key to complete the setting. Hopping frequency range is depends on the carrier wave, the frequency
setting of the carrier wave can refer to
Set Frequency for Carrier Wave
in AM mode.
Set FSK Rate
When the modulation source is internal, it can set the frequency of movement between the frequency of
carrier wave and hopping frequency. When FSK mode is enabled, it can set FSK rate (the range is 2 mHz
～
100
kHz). The default is 100 Hz. It can be change by multifunction rotary knob and arrow keys or press soft key
Rate
,
and then use numerical keyboard to input number and select unit soft key to complete the setting.
Comprehensive Example
In FSK mode, set an internal 2 kHz, 1 Vpp sine wave as a carrier wave signal, set hopping frequency to 800 Hz
and make the frequency of the carrier wave and hopping frequency to switch at a frequency of 200Hz, the
setting steps as follows.
1)
Enabling FSK mode
Press Mode
Shape
FSK
to turn on FSK mode.
2)
Set Hopping Frequency and Modulation Rate
Base on the Step 1, press
HopFreq
soft key and use numerical keyboard to input 800 and then select the
unit of the parameter to
Hz
.
