Window 3 Mode
This control sets the window 3 signal mode that selects internal or external
operation. Internal window 3 mode uses the normal window generator to
generate window 3. External window 3 mode uses the Jump 2 trigger to generate
the window 3 signal. Window 3 is typically set to Jump 2 to perform a Window

"Window 3 Mode" attribute is set to Jump 2. Typically, Window 3 Mode can be
used with an external response clock connected as the source of Jump Trigger 2.
Window 3 Delay can be used to align an external response clock with the
incoming response data.
The valid delay range is from 0 to 15 with 2ns resolution.
