 The available frequency ranges from 2 mHz to 50 kHz, and the default value is

100Hz.
Notice that, this menu will be grayed out and disabled when external source is
selected.

To Set Pulse Width/Duty Cycle Deviation

Press WidthDeV (or “DutyDev”), input the desired value using numeric keyboard or
knob.
 Width Deviation represents the variation in width (in seconds) in the modulated

waveform from the width of the original pulse waveform.

Pulse width range: 0 s to 500 ks.

Width deviation cannot exceed the current pulse width.

Width deviation is limited by the minimum pulse width and current edge time

setting.

 Duty Cycle Deviation represents the variation in duty cycle (in %) of the

modulated wavefor m from the duty cycle of the original pulse waveform.

Duty cycle deviation range: 0% to 50%.

Duty cycle deviation cannot exceed the current duty cycle deviation.

Duty cycle deviation is limited by the minimum duty cycle and curr ent edg e time

setting.

When external source is selected, width deviation (or duty cycle deviation) is
controlled by the ±6 V signal level of the [Mod In] connector at the rear panel. For
example, if the width deviation is set as 10s, +6 V signa l level corr esponds t o 10 s
width change.
