The only way to raise the frequency resolution is to increase the time of the recording. Frequency resolution can be expressed as 1/t where t = recording time. For example, a recording time of 1 second will allow you to resolve to 1Hz, at 10 seconds you can resolve to 0.1 Hz, at 20 seconds you can resolve to 0.05 Hz.
