Press the Next soft key to search data existing after the current position. When
a match is found in a pattern search, the corresponding data in the analysis
result display on the right side of the screen is highlighted, and the ZOOM
display moves accordingly. In an indefinite data search, Data of the analysis
number in which indefinite data is present is highlighted.
Explanation
Analyzing Data
Setting the Analysis Conditions
Analyzes the data of CH2 or CH4 by setting CH1 or CH3 to a clock channel.
• Setting the Clock Channel
Set the clock channel to CH1 or CH3. When the clock channel is set to CH1, the data
channel is CH2; when the clock channel is set to CH3, the data channel is CH4.
Setting the Level
Set the level used to determine the rising or falling edge of the clock signal.
Selectable range: 8 divisions within the screen
Resolution:
0.01 divisions (For example, the resolution for 2 mV/div is 0.02 mV.)
Setting the Hysteresis
Selectable range: 0.3 divisions to 4.0 divisions
• Setting the Data Channel
Set the data channel to CH2 or CH4. When the data channel is set to CH2, the clock
channel is CH1; when the data channel is set to CH4, the clock channel is CH3.
Setting the Threshold Level
Set the level used to determine the data channel signal level (0, 1, or indefinite).
Thr Upper: Signal exceeding this level is determined to be 1.
Thr Lower: Signal below this level is determined to be 0.
If Thr Lower
≤
data signal level
≤
Thr Upper, the signal level is determined to be
“indefinite data.”
If indefinite data is found, “*” is displayed in the hexadecimal display box at the byte
where the indefinite data exists on the display screen of analysis results.

• Setting the Reference Point
Select the reference point used to start the analysis from the following:
Trigger Position: Set the reference point to the trigger position.
Manual:
Set the reference point in the range of –5 to 5 divisions.
