4.6.9 Dword Matcher
Dword Matcher is a dword pattern matcher that presents match and mask fields and a K ‐
Code Mask field. K ‐ Codes are control characters that are always used in the first byte of a
four ‐ byte ordered ‐ set. Of the K ‐ Code masks listed in the menu, D ‐ D ‐ D ‐ D is used for data
bytes, and K ‐ D ‐ D ‐ D is used for all ordered ‐ sets.
When you create a dword match, keep the following in mind:

The pattern can be inside or outside of frames (it does not matter if the pattern
is inside a frame or not).

Because the pattern can be inside or outside of frames, there is no offset.

You can make user ‐ defined ordered ‐ sets. (This is the reason this feature was cre ‐
ated.)

You can use any K/D pattern.
4.6.10 Reusing “Captured DWORDS” in Events
This feature will enable the user to reuse previously captured data inside a Frame event;
therefore some parts of the frame event can be changed during the jammer running
period in real time.
To use a captured DWord in a Frame Event, the user can right click on Data pane of the
Frame Event Properties dialog and choose “Replace with Captured DWord”. Then another
dialog will pop up and the user can specify which captured DWord (Capture DWord#0 to
Capture DWord#3) to use to replace the selected DWord at run time. A user can mask any
of the bytes of the captured DWord by using the Mask buttons provided in the “Replace
With Captured Data” dialog.
