Hi Any one me What are the DSA devices also brief description about them.Is pci-6025E a DSA device. Does PCI-6025E support for DMA ...? What are the benefits and drawbacks if any device doesnot support DMA.? thanks ajmal
Hi Ajmal, DSA stands for dynamic signal acquisition. DSA boards are good for measuring signals that are dynamic or changing in nature. Some typical examples would be sound and vibration signals coming from a microphone or accelerometer respectively. These signals typically have a very large change in amplitude over a small amount of time.
The PCI-6025E is not a DSA board. This is a multifunction DAQ board that has analog input/output functionality along with counters and digital I/O.
DMA stands for direct memory access. The PCI-6025E does have DMA. If a board does not have DMA then each time the data is sent from the data acquisition (DAQ) board to the PC memory it will have to involve the processor. If a DAQ board does have DMA then it has a direct channel to the PC memory and will not need to involve the processor to transfer data.
