MONITORING/REPORT Menu.
The MPEG test decoder is able to record errors that
occurred in the transport stream. A nonvolatile memory that accepts 1000 entries
is provided for this purpose. If all 1000 memory locations are occupied, the next
entry clears the first one, and the other 999 entries are shifted by one position.
Entry No. 1 becomes No. 0, No. 2 becomes No. 1, etc. The new entry is written
into the now empty position 999. The data in this report memory is retained even
after instrument power-off.
