Figure 18-8. Specify Pattern Pop-Up for Find Pattern
The pop-up varies depending on the base you choose and the number
of channels you assign to that label. If you press a key on the keypad to
open the pop-up, the character on the key is placed in the first location
of the pattern.
Enter your pattern in the pop-up and press SELECT. The pattern
appears under the label in the Find Pattern field.
As mentioned previously in "Base", if you specify ASCII as the base for
the label, you won't be able to enter a pattern. You must specify one of
the other numeric bases to enter the pattern. Then you can switch the
base to ASCII and see what ASCII characters the pattern represents. If
you choose Symbols in the Base field, you can use one of the symbols
specified in the Timing Symbol Tables as the pattern. The Find Pattern
field looks similar to that below:
