Explanation
This feature searches CH1 to CH4 and M1 to M4 waveform signals.
Search Type
The following search types are available. The search conditions of each search type are
the same as the trigger conditions for each trigger type. For details, see sections 6.6 to 6.8
and 6.10 to 6.12.
• Edge
Searches for points where the specified waveform passes thro
ugh a certain level on
the rising or falling edge.
• Edge (Qualified)
Searches for points where the specified waveform passes through a certain level on
the rising or falling edge while the qualification requirement is met.
• State
Searches for points where the logical AND or the logical OR of each waveform status
is met or not met.
•
Width
Searches for points where the pulse width of the specified waveform meets a given
condition. The following five conditions are available.
More than Searches for trailing edges of pulses that are longer than the specified time.
Less than Searches for trailing edges of pulses that are shorter than the specified time.
Between Searches for trailing edges of pulses that are longer than the specified time
T1 but that are shorter than T2.
Out of Range Searches for trailing edges of pulses that are shorter than the specified time
T1 or that are longer than T2.
Time Out Searches for points where the pulse width exceeds the specified time.
The following three conditions are added further to the pulse width conditions.
Pulse Makes searches based on the relationship between the specified waveform
pulse width and the specified time.
Pulse(Qualified) Makes searches based on the relationship between the specified waveform
pulse width and the specified time while the qualification requirement is met.
State Searches for either of the points described below.
• Points where the relationship between the state condition true or false
time and the specified time is met
• The DL9000 checks the state condition on the rising or falling edge of the
specified clock source. The DL9000 searches for the position where the
relationship between the period during which the normalized condition (high
when the state condition is true and low when the state condition is low) is
true or false and the specified reference time meets a certain condition for
the first time.
Level
Set the reference level for CH1 to CH4 and M1 to M4.
The selectable range is �10 divisions from the vertical position. The resolution is 0.01
divisions. For example, if the T/div setting is 2 mV/division, the resolution is 0.02 mV.
Hysteresis
Set the hysteresis for CH1 to CH4 and M1 to M4.
The selectable range is from 0.0 to 4.0 divisions. The resolution is 0.1 divisions.
Trigger hysteresis settings
and correspond to 0.6 divisions and 1.0 division.
Found Point
The found-point position is the same as the trigger point position. For details on the
trigger point, see sections 6.6 to 6.8 and 6.10 to 6.12.
