Arguments for
Command or
Response to
Query
1 byte, value of 0
Command or Query
and 1
State of built-in tester (BST), where:
0=Off
1=On
1 byte
Command or Query
Syntax: BCP=x, where x=BERT pattern
BERT Pattern:
0 = space
1 = mark
2 = 1:1
3 = 1:3
4 = 63
5 = 511
6 = 2047 (default)
7 = 2047R (or 2047 Alternate)
8 = Mil 188
9 = 2^15-1
A = 2^20-1
B = 2^23-1
1 byte, value of
Command only.
1 only
Restarts or resets the BERT monitor.
Example: BRM=1
1 byte, value of
Command or Query.
0, 1
Inserts 10E-3 BER.
0 = Off
1 = On
Example: BKE=1
1 byte, value of 0
Command or Query.
to 3
BERT config sync loss threshold.
0 = 256 bit errors counted in less than 1000 bits o data
1 = low (100 bit errors in less than 1000 bits of data)
2 = med (250 bit errors in less than 1000 bits of data)
3 = high (20,000 bit errors in less than 100,000 bits of data)
7 bytes, numeric
Query only.
BERT monitor results in bit errors. If bit errors exceed 9999999, then
BRE=9999999.
