After enabling PWM, press the Dty Cyc Deviation softkey. Then use the
knob or numeric keypad to enter the desired deviation.
Go to the Pulse Screen, press the Width softkey and switch to Duty
Cycle.
Press the Modulation Key. Instead of “Width Deviation” the softkey
will be labeled “Dty Cyc Deviation” and the value to be entered will
be in % instead of seconds.
The width representation can be changed directly on the PWM screen
by pressing the Width Deviation or Dty Cyc Deviation softkey. (shown in
the figure below)
