When the rotating knob is pressed, the window that corresponds to the selected parameter
opens:

Figure 76.-

COFDM parameter options

In the Offset option, if the COFDM channel has a frequency deviation, you can apply an offset
(

0, 1/6, 2/6, 3/6, -1/6, -2/6, -3/6, Auto

) to correct this deviation. 

This 

will only be valid in channel mode

and you can select it by choosing the current COFDM

channel. 

The selection can be 

manual

or 

automatic

. When you select the automatic option, the

equipment will automatically detect the offset. This may take a few moments as a scan is
carried out for with all the possible offsets.

Figure 77.-

Determining a COFDM offset

The parameter window will display the information on the constellation being used in each
carrier and the code rate in yellow.

Possible options that can be
selected with the Spectrum
Inversion parameter using
the rotating knob
