Search Start Point
You can set the search start point. The selectable range is
±
5 divisions. The resolution is
ten division
÷
display record length. For a description of the display record length, see
appendix 1.
However, when Clock CH is set to None, the start point for searches is defined as
follows.
• Taking the first rising or falling edge located to the right of the specified Start Point on
the screen as the reference point, the search start point is set to the point 1/2 the
specified interval to the right of the reference point.

• When the interval between the Start Point and the search start position defined above
is greater than the detection interval, the search start point is set by moving the point
back by intervals specified by Interval so that the interval between the Start Point and
the search start point is within Interval and the Start Point is not exceeded (the search
start point shall not be to the left of the Start Point on the screen).

• Rising and falling edges are not detected in the hysteresis range (including the upper
and lower limits of hysteresis) of the Clock CH.
Parallel Pattern Search Conditions
The following conditions can be specified.
Clock Channel
Detects the status pattern in sync with the selected clock signal (clock channel).
• For the DL735E/DL1740E/DL1740EL
You can select from CH1 to CH4, and None.
• For the DL1720E
You can select from CH1 to CH2, and None.
When the Clock Channel Is Set to None
The status patterns of all waveforms are determined.
