The Format Menu
Symbols Field
Symbol Width Field
The Symbol Width field is used to specify how many characters of the symbol
name will be displayed when the symbol is referenced in the Trigger,
Waveform, and Listing menus.
To change the Symbol Width, simply highlight the field and turn the knob to
set the number of characters in the symbol. You can set the logic analyzer to
display from 1 to 16 of the characters in the symbol name.
Symbol Name Field
When you first access the symbol table, there are no symbols specified. The
symbol name field reads "New symbol." When this field is selected, a cursor
appears and you can then type a symbol name up to a maximum of 16
characters. Press the Done key when you are finished.
When you select Done, a symbol Type field becomes active. The symbol
Type field is used to define the symbol type as either a pattern or a range.
When you select this field, it toggles between pattern and range.
Pattern Type Field
When the symbol is defined as a pattern, a Pattern/Start field appears to the
right of the Type field. Use this field to specify what the pattern is. To assign
a pattern, highlight the Pattern/Start field and type in the desired pattern.
Range Type Field
If the symbol is defined as a range, a Pattern/Start field and a Stop field
appears. Use these fields to specify the upper and lower boundaries of the
range.
To assign pattern values to the boundaries, highlight the fields and type in
the pattern with the front-panel keypad. You can specify ranges that overlap
or are nested within each other.
