Test software computes the result so there is no need to look at a display. However, if you want to, my software (Soundforge 10c) can scale the display window for any desired range, e.g.blow up the entire horizontal scale to go from 6900 to 7100 Hz. The FFT itself has more than enough frequency resolution with 65K points and Blackman Window.
