Rotational Pulse Mode:
Variable Pulse Width (by angle), Preset Angular Position
In this mode, the angular pulse width is controlled by the algorithm, and the
angular position is preset before INIT. See Figure 23. Use the following
command sequence:
SOURce:FUNCtion:RPULse (@<ref_channel>),(@<ch_list>) to select the
channels that will output angular positioned pulses, and to specify the
reference channel.
