Agilent 81250 Parallel Bit Error Ratio Tester, Programming Reference, March 2006

:INPut:OCOMpensation

N O T E

Valid only for E4869A/B (DEMUX) modules.

Syntax

:<Handle>[:CGRoup*]:MODule*:CONNector*:INPut:OCOMpensation <value>

Definition

By default, the decision threshold for sampling the incoming signal is

set according to the mean value of the data signal. This is adequate for

pure PRBS data. In cases where the received pattern has an

unbalanced ratio of zeros to ones, this command allows you to fine-

tune the threshold to an appropriate value.

An inadequate offset can be suspected, if:

• None of the analyzer terminals could synchronize.

• All analyzer terminals did synchronize, but exhibit an abnormally

high BER.

• Some analyzer terminals did synchronize but show a BER close to

the synchronization threshold, while others did not synchronize at

all.
