2 Features and Functions

Modulating Waveform

The modulating waveform consists of Sine, Square, Ramp,

Negative Ramp (Nramp), Triangle, or Arbitrary waveform.

The default waveform is Sine wave.

• Square has 50% duty cycle

• Ramp has 100% symmetry

• Triangle has 50% symmetry

• Negative Ramp has 0% symmetry

Soft Front Panel Operation

Select the desired modulating waveform from the drop down

list as shown in Figure 2- 20.

Modulating Waveform Frequency

The range of the modulating waveform frequency is 2 mHz

to 20 kHz. The default modulating waveform frequency is

10 Hz.

Soft Front Panel Operation

On the Mod Frequency panel as shown in Figure 2- 20, input

the desired modulating frequency value and select the unit

from the drop down list.
