4.9.1.4 Measuring the Power of Digital Channels (Channel power)

The PROLINK-4/4C Premium offers two different methods to measure digital
channels power, according to the active operation mode: Automatic method in TV
mode and Integration method in Spectrum mode. The Automatic method measures
digital channel power in the measurement filter bandwidth and estimates total channel
power assuming that spectral density is uniform throughout channel bandwidth. On the
other hand, the Integration method takes into account signal spectral distribution so
measurement is more accurate but slightly slower (see 4.10.2 Selecting the
Measurements Mode). The obtained measurements using these methods may differ
some dBs, specially when the digital signal is degraded.
