When the Clock Channel Is Set to CH1 to CH4(2)
You can set the detection slope, level, and hysteresis of the selected synchronization
clock signal.
• Slope
You can select which slope edge, rising or falling, of the synchronization clock is to
be detected.
: Rising slope
: Falling slope
• Level
You can set the level for detecting the synchronization clock. The selectable range
is eight divisions within the screen. The resolution is 0.01 divisions.
• Hysteresis
You can set the hysteresis. The selectable range is 0.3 divisions to 4.0 divisions.
The resolution is 0.one 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.
Waveform to Search
The search target waveforms are all the waveforms that are not selected as the clock
channel. For each waveform, you can set the determination status (Pattern) and the level
and hysteresis for determining the status.
• Determination Status
The status of each waveform can be specified using the H (High), L (Low), and X
(Don’t Care) symbols.
H:
Status When Thru Upper Is Exceeded
L:
Status When Thr Lower is Not Reached
X:
No determination.
• Level
You can set the level used to determine whether the status is high or low. The
selectable range is eight divisions within the screen. The resolution is 0.01 divisions.
• Hysteresis
You can set the hysteresis. The selectable range is 0.3 divisions to 4.0 divisions. The
resolution is 0.one divisions.
• When the search target waveform exceeds the specified upper limit of hysteresis, it
is determined to be high.
• When the search target waveform is below the specified lower limit of hysteresis, it
is determined to be low.
• The status when the search target waveform is within the specified hysteresis
(including the upper and lower limits of hysteresis), A and B in the figure below) is
determined to be the same status (true) as the determination status (Pattern)
described two sections earlier, and is handled as a level where the search
condition is met.
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.
