Using a digital signal analyzer, which measurements are typically taken to troubleshoot a digital television signal?

The correct response highlights key parameters that are crucial for evaluating the integrity and quality of a digital television signal. When using a digital signal analyzer, measuring the carrier average power level is essential because it indicates the strength of the signal being transmitted. A stable and appropriate power level is necessary for reliable signal reception.

The modulation error ratio (MER) is another vital measurement, as it assesses the quality of the modulation scheme used in the transmission. A higher MER indicates a cleaner signal with less distortion, which is critical for maintaining quality in digital television broadcasts.

Bit error rate (BER) measures the number of erroneous bits in a transmitted data stream compared to the total number of bits transmitted. A lower BER is an indicator of a more reliable and effective transmission, ensuring that the received signal maintains the intended quality for viewing.

Together, these measurements provide a comprehensive view of the signal's performance, allowing technicians to identify and address any issues that might affect the viewing experience. They reflect both the physical characteristics and the performance of the digital television signal, making them essential for effective troubleshooting.
