Real-Time Data Acquisition
Real-Time Data-Acquisition function of PERUN PowerDesk supports most features usually encountered in digital oscilloscopes, including selection of sample-time, decimation and triggering. However, in combination with PowerDesk Dynamic Systems Toolkit, it provides so much more.
Real-Time Data Acquisition supports up to 8 analog channels. Each channel is associated with a variable in the memory of the underlying DSP control device, and the waveform corresponding to that variable, sampled with an appropriate rate and decimation, is transferred to PERUN PowerDesk during an active data acquisition session. Collection of the underlying waveform may be automatic or triggered. In automatic mode, a new waveform is being collected as soon as the previous one has been transmitted. In the triggered mode, collection of the new waveform is initiated only after trigger condition has been fulfilled.
Real-Time Data Acquisition function is fully integrated with Dynamic Systems Toolkit, thus enabling processing of live signals. What this means is that a user can define signal transformations, filtering, computation of spectra, etc. directly on analog channels transferred from the underlying control device. As soon as waveforms associated with these channels change, the change will be reflected on all dependent signals, for example those obtained by filtering, as well as on the computed spectra.
