Waveform Generation Tutorial
HDG2000 Series Arbitrary Waveform Generator 55
4. Specify the index of the Harmonic Wave order, press the F1 button when in the harmonic wave
menu, then the button is lighting. Use the knob and digital keyboard to modify parameter values;
5. To modify the amplitude of specific harmonic wave, press F2 button when it displays harmonic
wave menu, resulting of lighting on the buttons;
6. To modify the phase of specific harmonic wave, press F3 button. When in the harmonic wave
menu, then the button is lighting;
7. To modify the effective harmonic wave, press F5 button to select desired type in the harmonic
wave menu.
8. Oscilloscope shows harmonic wave.
9. To change the parameters after being highlighted, user can use the front panel knobs and
digital keyboard to input parameter values. Please refer to the <Method of inputting parameters>.
4.8 Method of input params
There are two methods
1. Input by digital keypad in the front panel. Input the params to the dialog showed and choose
units to confim or choose cancel to cancel.
2. Input by knob button and direction buttons. Select bit in the params by direction buttons and
increase or deincrease the value of the bit using konb button.
4.9 Mode Waveform
AM
Amplitude Modulation. AM make the high frequency carrier signal amplitude changes over
modulation signal's instantaneous value.
FM
Frequency Modulation. Frequency modulation represent information to the change of
instantaneous frequency of the carrier wave.
PM
Phase Modulation. PM is a form of modulation that represents information as variations in the
instantaneous phase of a carrier wave
ASK
Amplitude Shift Keying. ASK is a form of amplitude modulation that represents digital data as
