Analyzing and Searching Waveforms
• Slope
You can select which slope edge, rising or falling, of the synchronization clock is to
be detected.
Rising slope
Falling slope
• Hysteresis
You can set the hysteresis. The selectable range is 0.3 divisions to 4.0 divisions.
The resolution is 0.1 divisions.
• When the level of the search target waveform changes from below the specified
lower limit of hysteresis to above and including the upper limit of hysteresis, it is
detected as a synchronization clock.
• When the level of the search target waveform changes from above the specified
upper limit of hysteresis to below and including the lower limit of hysteresis, it is
detected as a synchronization clock.
• For all other cases, it is not detected as a synchronization clock.
Search Target Waveform
You can select the search target waveform.
DL7440
You can select the target waveform from CH1 to CH4, Math1, Math2, Pod A, and Pod B.
DL7480
You can select the target waveform from CH1 to CH8, Math1, Math2, Pod A, and Pod B.
* In the case of the logic input (Pod A and Pod B), you can select the search target bit.
Level for Determining the Status
You can set the level for determining the status of the search target waveform. The
selectable range is 8 divisions within the screen. The resolution is 0.01 divisions. Thr
Upper must be greater than or equal to Thr Lower.
Level for determining high (Thr Upper)
You can set the level for determining the high status. When the search target waveform
exceeds the specified level, it is determined to be high.
Level for determining low (Thr Lower)
You can set the level for determining the low status. When the search target waveform is
below the specified level, it is determined to be low.
Between Thr Upper and Thr Lower
The status when the search target waveform is between the levels specified by Thr Upper
and Thr Lower (including the Thr Upper and Thr Lower values) (A and B in the figure below)
is determined to be the same status (true) as the status at the same point of the
determination pattern specified on the next page and is handled as a section where the
search condition is met.
