To Set Pulse Width/Duty Cycle Deviation
Press WidthDeV (or “DutyDev”) and input the desired value using the numeric
keyboard or direction keys and knob.
Width deviation represents the variation (in seconds) of the modulated
waveform pulse width relative to the original pulse width.
Pulse width deviation range: 0s to 500ks.
The width deviation can not exceed the current pulse width.
The width deviation is limited by the minimum pulse width and current edge
time setting.
Duty cycle deviation represents the variation (in %) of the modulated
waveform duty cycle relative to the original pulse duty cycle.
Duty cycle deviation range: 0% to 50%。
The duty cycle deviation can not exceed the current pulse duty cycle.
The duty cycle is limited by the minimum duty cycle and current edge time
setting.
When “Ext” modulation source is selected, width deviation (or duty deviation) is
controlled by the ± 2.5V signal level at the [Mod/FSK/Trig] connector at the rear
panel. For example, if the width deviation is set to 10s, the +2.5V signal level
corresponds to a 10s variation in pulse width.
