Note
•
If an arbitrary data is selected (highlighted) in the analysis data slit, the zoom position
moves to the beginning of the data. Conversely, if you move the zoom position, the data
corresponding to the zoom position is highlighted.
•
If the CS signal is ON and the CS signal on the main waveform display screen does not
contain a transition point from H to L or L to H, the I/O data is not analyzed.
•
Analysis and search is not possible while waveform acquisition is in progress.
•
Analysis and search cannot be performed on accumulated waveforms. However, analysis
and search are possible on the accumulated waveform remaining as a history waveform.
Detailed List of Analysis Data: Detail
More detailed information of the analysis data can be listed. The following information
can be displayed.
• Analysis number
• Time from the reference point
Displays the time from the reference point to the first bit of each data point.
• Data1 and Data2 values
You can display the values by selecting hexadecimal or binary for the notation
system. However, if the data does not consist of 8 bits or if indefinite data exists, the
display is the same as “Data1 and Data2 Values” on page 2-28.
• CS signal status
