Digital computation
The following table details the optional DSP modules that can be added to OR34 hardware to fit analysis mode calculation needs.
SPUs
SPU (Signal Processing Units): the following table gives the characteristics of each analysis mode and the associated SPU consumption. For multi-analysis purpose, add the corresponding SPUs of each mode used simultaneously and increase the sum by 10%. "Real-time" means that the analysis speed is faster than the input rate and does not miss any sample.
