3.3.3.3.1.- Search level
This parameter defines the threshold that the video carrier must surpass for the equipment to
tune a specific channel when carrying out an automatic search. When this function is selected,
a window opens onscreen, and the value of the search level can be modified using the rotating
knob. The possible values range from 40 and 120 dBµV.
It is best to program a search value that is close to the signal level that we are using in the
equipment, in other words, if we want to scan through the channels of a headend quickly using
this function, if the headend output is at approximately 115 dbµV, the correct way to proceed
is to program search values that are higher than 110 dbµV.
If we enter values that are very low compared to the level that we are using (for example
60 dbµV in this case), we are helping to saturate the equipment and using this function
incorrectly.

3.3.3.3.2.- Next
This tunes the channel that has a video carrier level that surpasses the search level and that is
immediately next in frequency to the tuned channel.
3.3.3.3.3.- Previous
This tunes the channel that has a video carrier level that surpasses the search level and that is
immediately before in frequency to the tuned channel.
