When you activate this option by pressing key ENTER on the item, the
CONTINUOS
option (in measure MENU) is automatically deactivated. If you
press the ENTER key again, the
FFT
option is also deactivated.
When the “
Enable sampling for FFT
” option is selected, a series of samples
are acquired and saved in the internal memory after the measurement; this
allows the machine pulsations detected during measurement to be analysed
using the OptiWave™ software or external FFT packages.
“
Sample freq.
” Set the frequency of data sampling for FFT analysis.
“
Sample length
” Set the duration of data sampling for FFT analysis. The
higher the sampling frequency, the lower the maximum sampling duration that
can be selected.
