3.3.3. Sample rate
One of the most important settings is the sample rate. The sample rate defines how many data points
Krypton will transfer to the Dewesoft. Higher sample rate also means that more data needs to be
transferred via EtherCAT to your computer.
The sampling speed mainly depends on your application. To display your signal in a time domain with a
good time resolution, you should sample 10 to 20 times faster than the frequency of the signal that you
want to measure, e.g. 1000 S/sec for a 50 Hz sine-wave. If you have a lot of high frequency components, it
may be necessary to sample 100 times faster, e.g. 5000 S/sec for the 50 Hz sine-wave, or even more. If you
display only the frequency domain (FFT analysis), a 2.5 times faster sampling would be sufficient
(125S/sec for the 50 Hz sine-wave). The higher the sampling rate, the better the time resolution. But also
the file size will increase. In the following image you can see that the maximum sample rate is different
for Krypton devices. For example the STG module has max. 20 kS/sec and TH module has a max. 100
S/sec of sampling rate. The Krypton ONE family has a 40 kS/sec maximum sample rate with the Krypton
1xACC exception which has a sample rate up to 50 kS/sec.
