*1 The next pulse width after 5 ns is 10 ns.
*2 When the width condition is set to PULSE<T, the smallest setting range is 5 ns; when the
width condition is set to PULSE>T or TIMEOUT, the smallest setting range is 30 ns.
Selecting the trigger source/state and setting the trigger level
The trigger source should be selected from CH1 to CH4
Select the trigger state from the following.
