Description of Arguments
Query
Command or Query.
Sets BERT config sync loss threshold in the form x, where:
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)
Command or Query.
Inserts 10E-3 BER in the form x, where:
0 = Off
1 = On
Example: BKE=1
Query only.
BERT monitor results in bit errors.
If bit errors exceed 9999999, then BRE=9999999.
Command only.
Restarts or resets the BERT monitor.
Example: BRM=1
Query only.
Returns the value of the average BER in the form a.b x 10
First 3 bytes are the value.
Last 2 bytes are the exponent.
Returns 99999 if there's no sync in BERT monitor.
Returns 99.99 if sync loss has occurred.
Example: BER=4.8E3 (BER = 4.8 x 10
Command or Query.
Sets state of built-in tester (BST) in the form x, where:
0=Off
1=On
