Analyzing and Searching Waveforms
8. Use jog shuttle & SELECT to select the slope, rising or falling, for detecting the
synchronization clock (Polarity box).
Set the level for detecting the synchronization clock.
Set the hysteresis (width of the level used to detect
the synchronization clock).
Select which slope edge, rising or falling, of the
synchronization clock is to be detected.
Setting the Level for Determining the Status (1 or 0) of the I/O Data
9. Use jog shuttle & SELECT to select whether Data1 (CH2) is to be analyzed
(ON/OFF) (Data1 (CH2) box).
• Data1 (CH2) will be analyzed when the mark to the left is highlighted.
• When interleave mode is ON, you cannot set Data1 (CH2).
10. Use jog shuttle & SELECT to set the level for determining whether the status of
Data1 (CH2) is 1 (Thr Upper box).
11. Use jog shuttle & SELECT to set the level for determining whether the status of
Data1 (CH2) is 0 (Thr Lower box).
• When the data exceeds the specified level (Thr Upper), it is determined to be 1.
• When the data is below the specified level (Thr Lower), it is determined to be 0.
• When the data is between the levels specified by Thr Upper and Thr Lower (including
the Thr Upper and Thr Lower values), it is determined to be indefinite data.
12. Repeat steps 9 to 11 to set the level for determining the status of Data2 (CH3).
Select whether the data is to be analyzed (ON/OFF).
Set the level for determining whether the data
status is 1.
Set the level for determining whether the data
status is 0.
Setting the Chip Select Signal (CS)
• When Using CH4 to CH8 (CH4) for the CS Signal
13. Use jog shuttle & SELECT to select the CS signal from CH4 to CH8 (CH4) (CH
Level box).
The only channel that can be used on the DL7440 is CH4. You can select from CH4 to
CH8 on the DL7480.
14. Use jog shuttle & SELECT to set the level for determining the status of the CS
signal (CH level box on the right).
15. On the DL7480, repeat steps 12 and 13 as necessary to set the level for
determining the status of CH5 to CH8 as necessary.
16. Use jog shuttle & SELECT to select whether to make the channel a CS signal
(ON/OFF) (each CH box).
The channel is enabled as a CS signal when the mark to the left of the channel is
highlighted.
Select a channel from CH4 to CH8 (4).
Set the level for determining the status of
the CS signal. (On the DL7480, set the
level for determining the status of CH5 to
CH8 as necessary.)
Select whether the channel is to be a CS
signal (ON/OFF).
