UTG2000B Series 53
Hop Frequency Setting
After enabling FSK function, the default of hop frequency is 2MHz. If need to change, press Param →
HopFreq in turn. Settable range of hop frequency is determined by carrier wave waveform. See Carrier
Wave Frequency Setting
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
1MHz, the default rate is 100Hz. If need to change, press
Param →
Rate in turn. Please refer to Carrier Wave Frequency to set up the frequency.
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:
3) Enable Frequency Shift Keying (FSK) Function
Press Menu → Mod → Type →
FSK in turn to start the FSK function.
Set Carrier Wave Signal Parameter
Press Carrier → Type →
Sine in turn to select sine wave as carrier wave.
