Zoom rate (Z1 Mag)
The upper limit of the zoom rate is determined from the display record length as follows:
Display record length divided by 50 (or 40)
The display record length does not necessarily match the record length.
For details on the display record length, see appendix 1, “Relationship between the Time
Axis Setting, Sample Rate and Record Length” in the
DL7100/DL7200 User’s Manual
(IM701410-01E).
Zoom position (Z1 Position)
The zoom position can be set by specifying the zoom center position (center of the zoom
box) in the range –5 to +5 divisions with the center of the waveform display frame set to
0 divisions. When the record length is 16 Mwords, the zoom position can be set only in
the range in which the edge of the waveform matches the edge of the window. The
selectable steps is as follows:
Selectable steps of zoom position: T/div

Performing a Pattern Search (Search Setup)
Search the waveform by specifying a field or frame pattern. When a waveform that
matches the pattern is found, the Zoom Box moves to that point and displays the
specified waveform in the Zoom window. Indefinite data can be specified and searched.
Pattern search and indefinite data search cannot be executed simultaneously.
For a pattern search, indefinite data is searched when the value set in the menu is 1 or 0.
Setup Data
Type: Specify the type of data to be searched.
Frame Pattern: Search for field or frame patterns.
Indefinite State: Search for indefinite data.
If you selected Frame Pattern, set the following item.
Message Format: Select whether the ID field is standard or extended.
Std: Standard format (11 bits)
Ext: Extended format (29 bits)
Pattern Format: Specify the pattern display format.
Hex: Hexadecimal notation
Bin: Binary notation
Setting the pattern: Specify multiple patterns from Identifier, RTR, Data Field, ACK,
and Error. Searches for data that matched all the specified
patterns (AND condition).
Executing the search (Next, Previous)
• When Patterns Are Searched
Press the execution key corresponding to the direction in which the search is to be
performed from the current selected frame.
Next:
Executes the search on frames that are after the current selected
frame.
Previous: Executes the search on frames that are before the current selected
frame.
• When Indefinite Data Is Searched
Next:
Executes the search on data that is after the current Zoom Position.
Previous: Executes the search on data that is before the current Zoom Position.
