Amplitude Modulation (AM)
An AM (Amplitude Modulation) modulated waveform consists of carrier waveform and
modulating waveform. The amplitude of the carrier waveform varies with the
instantaneous voltage of the modulating waveform.
To Select AM Modulation
Press Mod  Type  AM to enable AM function.
 When Mod is enabled, Sweep or Burst will be disabled automatically (if
enabled currently).
 After AM is enabled, the instrument will generate AM waveform with the current
specified carrier and modulating waveform.
To Select Carrier Waveform Shape
AM carrier waveform shape could be Sine, Square, Ramp or Arbitrary waveform. The
default is Sine.
 Press the front panel key Sine, Square, Ramp or (Arb Select Wform) to
select a desired carrier waveform shape.
 Pulse (basic waveform), Noise and DC could not be used as carrier waveform.
To Set Carrier Frequency
After the carrier waveform shape is selected, you can press Freq/Period to highlight
“Freq”, and then use the numeric keyboard or knob to input desired frequency value.
The available carrier frequency varies with different carrier waveforms.
 Sine: 1 μHz to 350 MHz
 Square: 1 μHz to 120 MHz
 Ramp: 1 μHz to 5 MHz
 Arbitrary waveform: 1 μHz to 50 MHz
