At what point does the FVD audibly tone? - Correct Answer 50 volts What is the downstream/Rx bandwidth range? - Correct Answer 50-860 mHz What is the upstream/Tx bandwidth range? - Correct Answer 5-42 mHz What is MER? - Correct Answer Modulation Error Ratio, It is a measure of how the QAM signal is received. Similar to a target for a bow and arrow, a perfect hit would be dead center with no varying points askew. This is literally represented in a constellation view.What is BER? - Correct Answer Bit Error Rate, It is the number of bit errors per stream of bits. This is found by dividing the number of errors by the number of bits sent. This is also known as the quality of signal being transmitted. In the bow and arrow analogy, BER is represented by the arrow.What is the MER range amount to pass on the meter? - Correct Answer 33-51 dBmV What is the ideal measurement for BER? - Correct Answer 1.0E-9 What is ingress? - Correct Answer Unwanted signal leaking into the cable due to service issues or faulty equipment What is egress? - Correct Answer When signal leaks out due to a break, tear, or loose/improper fittings What is the maximum ingress that can be measured and still pass on the meter? What is the ideal amount? - Correct Answer -35dBmV is the max, -51dBmV is the ideal What is the range of levels that your CPE can fall at, in terms of power, and still pass? - Correct Answer - 10 to 12dBmV When will a transmit level fail on the meter? - Correct Answer 51dBmV
