Interleave Factor]).
Number of good transfer frames received from the Reed Solomon decoder. Reset
to 0 when the Frame Synchronizer or the Reed Solomon decoder is set to OFF or
by clicking on in the upper tool bar (the DPU window must be active).
Number of bad transfer frames received from the Reed Solomon decoder. Reset
