Sencore has a model AT 1506 8VSB RF signal analyzer that displays parameters called "pre RS BER", "SER", and "post FEC". Unfortunately, it costs about $8,000, so I put together my portable WINTV-D signal monitoring assembly in hopes of it functioning as a suitable BER meter until someone incorporates that measurement feature in a less expensive meter. I have a hunch that the pre RS BER is what I should be trying to peak (meaning zero-out). Can any computer guys out there define those three terms for me, so that I can better decide if the Sencore meter will do something useful for me that the WINTV-D bit-error-rate meter does not? [/b]

By guess or by golly:


pre RS BER = pre Reed-Solomon Bit Error Rate. This would be the raw error rate.


SER: Segment Error Rate.


post FEC: Post Forward Error Correction.


These seem like reasonable guesses. Further interpretations, corrections welcome.
