To Set Pulse Width/Duty Cycle Deviation
Press Width DeV (or Duty Dev) and input the desired value using the numeric
keyboard or direction keys and knob.
 Width deviation represents the variation (the available units are ns, μs, ms, s
and ks) of the modulated waveform pulse width relative to the original pulse
width.
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.
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 external modulation source is selected, width deviation or duty cycle deviation
is controlled by the ±5V signal level of the [CH1/Sync/Ext Mod/Trig/FSK]
connector at the rear panel. For example, if the width deviation is set to 10s, the +5V
signal level corresponds to a 10s width variation.
