Output Channel Video Carrier Frequencies
The following table lists the 82 EIA channel numbers and their corresponding DSAN
output video carrier frequencies. These carrier frequencies meet specification for the
Standard Channel plan, but may differ slightly from the nominal channel plan. To
accurately measure the DSAN RF levels, you may need to calibrate power meters to
the following frequency chart. Failure to do so may result in inaccurate level settings
that could adversely affect downstream quality and performance.
