Hi,

I'm trying to record some acoustic signals using an ADC 216 and Picolog in order to analyse it with a home-made Matlab routine. I've tried to set the sample frequency at 1 kHz, but it doesn't seem to be the real sample frequency...

How can I know for sure the sampling rate with picolog? (I've made some tests with a frequency generator and the "power spectrum density" function of Matlab that shows the 1kHz freq. given in picolog is not the real sampling rate)...

help is all I need !

thanks alot
