Mydaq DSA, increasing the resolution of the FFT?

[swouters]

Dear,

Is it possible to increase the resolution of the FFT?

The frequency span can not be set lower than the resolution lines.

So the highest resolution of the FFT is 1 Hz.

Measuring for example with 800 lines and a span of 400 Hz is not possible.

Is there a program that can measure with a resulotion of 0.5 Hz or 0.25 Hz?

Attached a logged file of the Mydag DSA instrument.

Regards,
