"Interlaced"
Interlace scanning uses two fields to create a frame. One field con-
tains all the odd lines (odd, first, or upper filed), the other contains all
the even lines of the image (even, second, or lower field). First the
lines of the odd filed are processed, then the lines of the even field.
"Progressive"
Progressive scanning is a method to capture, transmit and display all
lines of a frame in sequence.
"Segmented"
Progressive segmented frame uses progressive scanning to capture
the frame, and interlaced scanning for transmission and display.
2.5.6 Pattern Trigger (R&S RTH-K19)
The pattern trigger works like a logic trigger. It provides logical combinations of the
input channels and can be used for verifying the operation of digital logic. If the chan-
nel states match the desired pattern, the pattern trigger occurs. In addition to the pat-
tern, you can define a timing condition. In this case, the trigger occurs if the pattern
definition is true for the defined time.
