* '''Number of lines''': The FFT number of analyzed lines. There are seven possibilities: 101, 201, 401, 801, 1601, 3201 or 6401 lines. | * '''Number of lines''': The FFT number of analyzed lines. There are seven possibilities: 101, 201, 401, 801, 1601, 3201 or 6401 lines. | ||
* '''Trigger Frequency:''' This setting is only available when the ''FFT x/Average/Domain ''setting is "Synchronous". The value can be chosen from the FFT Frequency range; this frequency is the phase reference: each FFT block is recomputed so that the phase of the frequency chosen is 0. | * '''Trigger Frequency:''' This setting is only available when the ''FFT x/Average/Domain ''setting is "Synchronous".
