The value indicates absolute count of data bits received
since synchronization.




BIT ERROR RATE:

{M.ppE+ee}

This is a read only status value. This is a scientific
notation value where the mantissa is given with two-point
precision and the exponent may be as large as +32.


The value indicates absolute count of bit errors divided
by the absolute count of data bits received since
synchronization.


RUN TIME:

{DD:HH:MM:SS}

This is a read only status value. This displays the
Days:Hours:Minutes:Seconds that the test has been
running without an interruption in synchronization.


TEST RESET:

{}

Pressing the enter button on the front panel will reset test
measurements but not the test pattern. The test values
are updated as soon as synchronization is achieved.


OUTER FEC:

{NORMAL, BYPASS}

Test mode to allow bypassing the LDPC decoder.
Available when DVBS2 is selected.


INNER FEC:

{NORMAL, BYPASS}

Test mode to allow bypassing the BCH decoder.

Available when DVBS2 is selected.


INTERLEAVER:

{NORMAL, BYPASS}

.


BB SCRAMBLER:

{NORMAL, BYPASS}

Test mode to allow bypassing the base band scrambler.

Available when DVBS2 is selected.


PL SCRAMBLER:

{NORMAL, BYPASS}

.







ETH DEST MAC

{

XXXXXXXXXXXX}

This field allows the operator to enter a Destination MAC
address to be used by the Ethernet Data Interface.
When this field is non-zero, the Ethernet Data Interface
will use this value for the Destination MAC address
instead of trying to resolve the Destination MAC address
in the normal manner. When this field is zero, the
