After enabling FSK function, the default of hop frequency is 2MHz. If need to change, press Parameter→Hop
Frequency in turn. Settable range of hop frequency is determined by carrier wave waveform. See the following
table for setting range of each carrier wave frequency:
Carrier Wave
Minimum
Value
Sine Wave 1μHz
Square wave 1μHz
Ramp Wave 1μHz
Arbitrary

FSK Rate Setting
When modulation source is internal, the moving frequency between carrier wave frequency and hop frequency can
be set. After enabling FSK function, FSK rate can be set and the settable range is 2mHz to 100kHz, the default rate is
1kHz. If need to change, press Carrier Wave Parameter→Rate in turn.
Comprehensive Example
Firstly, make the instrument work in frequency shift keying (FSK) mode, then set a sine wave with 2kHz and 1Vpp
from the internal of the instrument as a carrier wave signal, and set hop frequency to 800 Hz, finally, make carrier
wave frequency and hop frequency move between each other with 200Hz frequency. Specific steps are seen as
following:
1) Enable Frequency Shift Keying (FSK) Function
Press Menu→Modulation→Type→Frequency Shift Keying in turn to start the FSK function.
2) Set Carrier Wave Signal Parameter
Press Carrier Wave Parameter→Type→Sine Wave in turn to select sine wave as carrier wave.
