5.32. How to set the parameters of FSK
1. Press Mod function button, then press F1 to select Mod.
2. Press F1 to switch Mod Type to FSK. If the Carrier Waveform is not Sine, the
system will switch it to Sine automatically.
3. Press button to display the waveform and parameters of the Carrier
Waveform. You can change the parameters, please refer to “To Output Sine Signals”
on page 67. Press button again to return to the Modulation mode interface.
4. Press F5 to select the source. If the source is External, use the Ext
Trig/FSK/Burst connector in the rear panel to input the external signal, then skip
ahead to step (5). If you choose Internal, continue to the steps below.
5. Press F3 to set FSK Rate. The range is 2 mHz～100 kHz (Internal source only).
6. Press F4 to set Hop Frequency. The range is 2 mHz～25kHz.
Term Explanation
FSK Rate:
The frequency at which the output frequency shifts between the carrier frequency and
the Hop frequency (Internal Modulation only).
5.33. PWM (Pulse Width Modulation - only PeakTech
®
4165)
The modulated waveform consists of two parts: the Carrier Waveform and the Modulating
Waveform. PWM can only be used for pulse modulation, so the Carrier Waveform must be
Pulse. In PWM, the width of the Carrier Waveform (Pulse) varies with the instantaneous
voltage of the modulating waveform.
