Generating a DSB-AM Modulated Waveform

Generate a carrier wave

of type Sine, Square, Ramp, or Arb(itrary).

2. Before outputting, press the Front Panel

Mod

function button. You should see "Mod" appear next to the car-

rier wave type on the Channel tab, and the modulation parameter menu and value list on the display.

3. Press the

Type

softkey, then press the

DSB-AM

softkey.

4. Set the following DSB-AM parameters:

Modulation

Source

Internal

External

. If External is selected, attach the modulation source to the

Modulation In

connector on the Back Panel. You do not need to set any other parameters.

DSB Frequency

- If using Internal source, set a DSB frequency of up to 50 KHz.

5. Press the appropriate channel

Output

button to begin outputting the waveform.

Generating a PWM Modulated Waveform

Pulse-Width Modulation is used exclusively with Pulse type waves.

Generate a carrier wave

of type Pulse.

2. Before outputting, press the Front Panel

Mod

function button. You should see "Mod" appear next to the car-

rier wave type on the Channel tab, and the modulation parameter menu and value list on the display. The
modulation Type will be set to PWM.

3. Set the following PWM parameters:

Modulation

Source

Internal

External

. If External is selected, attach the modulation source to the

Modulation In

connector on the Back Panel. You do not need to set any other parameters.

PWM Freq

(uency) - the rate at which the pulse is modulated.

Width Dev

(iation) -modulating pulse width.

4. Press the appropriate channel

Output

button to begin outputting the waveform.
