Range That Can Be Analyzed
Analysis is performed on the acquisition data within the display screen. Up to 40000
bytes of the analysis results can be displayed. The displayed result varies depending on
the number of bytes analyzed as follows:
• When the total analysis result is less than or equal to 40000 bytes
All points are displayed regardless of the position of the Reference Point.
• When the total analysis result is greater than 40000 bytes
The displayed result varies depending on the number of analysis results on the Pre*
and Post* sides as follows:
• When the Pre side=30000 and the Post side=30000 -> Displays Pre side=20000
and Post side=20000
• When the Pre side=10000 and the Post side=50000 -> Displays Pre side=10000
and Post side=30000
• When the Pre side=50000 and the Post side=10000 -> Displays Pre side=30000
and Post side=10000
*
Pre:
Before (left of) the reference point
Post:
After (right of) the reference point
Notes When Performing Analysis
• Analysis and search cannot be performed while the waveform acquisition is started.
• Analysis and search cannot be performed on accumulated waveforms.
Analysis Data List (Analysis Result List)
The following three items are displayed.
• Analysis number
• Hexadecimal display of the analyzed data
• Acknowledge bit condition
Analysis Number: No.
Up to 40000 points can be displayed.
Hexadecimal Display of the Analyzed Data: Hex
The analyzed data is displayed using hexadecimal notation. However, if a byte of data is
less than 8 bits, the data is not displayed. If indefinite data exists, “
∗
” is displayed.
Indefinite data is considered the same value as the previous bit for the analysis. If the
first data is indefinite, it is considered 0 for the analysis.
Acknowledge Bit Condition: Ack
Displays the Acknowledge bit condition. Displays 0 if the Acknowledge bit is present;
displays 1 if the Acknowledge bit is not present.
Note
If you execute the analysis and select (highlight) an arbitrary byte in the list of analysis
results, the Zoom Position moves to the head of that byte. In addition, if you move the Zoom
Position, the highlighting moves to the corresponding byte in the list of analysis results.
