sine waveform. After select AM modulating, press Carrier soft key to enter the interface, press
Multipurpose knob to select the desired carrier wave as shown in Figure 17-4.
③ Carrier frequency
Different carrier wave has different frequency range. The default frequency of all
kHz. Frequency range for each carrier wave as shown in Table 17-1

Pulse Wave
Arbitrary Wave
Set carrier frequency after select the carrier wave. Adjusting Multipurpose knob, numeric keyboard to set
the frequency value.
④ Modulating wave
Modulating wave can be sine wave, square wave, rising ramp wave, falling ramp wave, arbitrary wave or
noise. The default is sine wave. When AM function is enabled, the sine wave will appeared. Adjusting
Multipurpose knob to select the desired modulating wave.
Square wave: duty cycle is 50%

Rising ramp wave: symmetry degree is 100%

Falling ramp wave: symmetry degree is 0%

Arbitrary wave: select the arbitrary wave as the modulating wave, function/arbitrary waveform
