Digitiser cards get FPGA-based signal averaging capabilites
Spectrum has created new firmware packages that allow its high-speed M4i series digitiser cards to perform on-board signal averaging by using the latest FPGA technology. The M4i.44xx series cards offer real-time sampling rates of up to 500 MS/s with 14 bit resolution and 250 MS/s with 16 bit resolution.
The new averaging package features ultrafast performance being able to acquire and average signals at rates of over 5,000,000 events per second.
The M4i series cards are available with two or four channels and, thanks to the cards fast PCIe bus, acquired and averaged data can be transferred directly to a host PC at speeds of up to 3.4 GB/s.
"The new averaging package, together with the M4i.44xx cards exceptional digitiser performance and fast PCIe bus, makes this development one of the most powerful averaging systems available today," said Spectrum Director of Technology, Oliver Rovini. "With these new FPGA based processing functions we are extending the capabilities of our digitizer products by improving measurement sensitivity and throughput. Engineers and scientists who are looking for faster, more accurate measurements for repetitive signals should find this development of interest."
