Chart marks

1. Chart marks
The found magnitudes can be marked in the measurement chart. You can select whether frequency and/or magnitude values are displayed numerically in the mark. Furthermore, the half-width can be marked optically.
By the function Overlap axes markers are displayed in the foreground, if they are overlapped by an axis.

Linear interpolation

2. Linear interpolation
Frequency analyses by FFT show discrete frequencies. In order to make it easier to identify the half-width, VM-FFT can interpolate linearly among these frequencies.

Ignore noise carpet

3. Ignore noise carpet
Ignore noise carpet determines which level is to be ignored as noise carpet during the finding of magnitudes. The more you move the controller to the right, the more is ignored and fewer magnitudes will be found.
