Tip: An easy way to select the number of samples and duration is to
let the instrument set them for you. Set the Equivalent Fmax so that
it covers your required frequency range; the instrument will select the
maximum number of samples and duration that can be used with this
Fmax. You can then adjust these values as required.
Duration
The Duration of a waveform is its recording time. The duration value
depends on the number of samples selected; increasing the number
of samples increases the duration.
