Hello DIYs',
I am in the process of getting to know the Liberty Instruments' Praxis software for measuring THD, FFT, frequency response, phase etc.
However, when I use the spectrum RTA 1 Channel acquisition I cannot make the software go below approximately 300 Hz in the measurement screen, although it is supposed to go down to 1 Hz, as set by the start frequency setting (see attached screen dump). I need to be able to go below 1 Hz (and up to around 100 kHz).
Any of you know this software and have suggestions as to how I do this? Also, if any of you have suggestions for other softwares that can measure these parameters I'd appreciate your feedback.
Need be not too expensive (free or < 100 USD).
Thanks, Jesper
