When inband selected, noise level is measured inside the channel
bandwidth during black lines transmitting. When outband selected, noise
level is measured outside the channel bandwidth at the frequency with
minimal signal level.

The initial parameter values are set during automatic channel plan definition and can
be corrected. To adjust the parameter value, select the desired parameter using the « »
and « » keys. The parameter is adjusted using the «◄», «►» keys or typed in directly
using the alphanumeric keys. You can scroll through the channels using the «F3» and
«F4» keys without returning back to the channel plan table.
4.3.12.3. New Channel Plan Creation
To create a new channel plan in the automatic mode, send a signal to the Analyzer
input press the «F3 / New» key and select «Scan» option. Enter the channel name in the
popup window and press «ENTER». After that the Analyzer will scan all TV channels and
enter the channel plan editing mode. Adjust the channel parameters and open the channel
