Setting the Search Conditions
4. Press the Setup soft key. The Setup dialog box opens.
Setting the Timing for Detecting the Status Pattern
5. Use jog shuttle & SELECT to select None (detect the patterns at a certain
interval), or a channel from CH1 to CH8/4 (synchronize to the selected channel
signal, Clock CH box).
• If you select None, proceed to step 6.
• If you select CH1 to CH8/4, proceed to step 7.
• You can select up to CH4 and CH8 on the DL7440 and DL7480, respectively.
• Setting the Interval for Detecting Patterns (When None Is Selected)
6. Use jog shuttle & SELECT to set the interval for detecting the pattern (Interval
box). Proceed to step 10.
• Setting the Detection Level, Slope, and Hysteresis of the Selected
Synchronization Clock Signal (When CH1 to CH8/4 Is Selected)
7. Use jog shuttle & SELECT to set the level for detecting the synchronization
clock (Level box).
8. Use jog shuttle & SELECT to select the slope, rising or falling, for detecting the
synchronization clock (Polarity box).
9. Use jog shuttle & SELECT to set the hysteresis (width of the level for detecting
the synchronization clock, Hysteresis box).
Set the interval for
detecting the pattern.
When Clock CH is
set to None
When Clock CH is
set to CH1 to CH8 (4)
Set the level for detecting the
synchronization clock.
Select which slope edge, rising or falling,
of the synchronization clock is to be detected.
Set the hysteresis (width of the level for detecting
the synchronization clock).
