sampling rates from 3.2 to 10 GS/s with 12-bit resolution and bandwidths from 1 to 4.7 GHz. All variants can transfer data over the PCIe bus at staggering 12.8 GB/s. The data can be sent to PC memory for storage, or directly to CPUs and CUDA-based GPUs for customized signal processing and analysis. Furthermore, the one and two channel cards offer up to 16 GB (8 GSamples) on-board memory. These innovative digitizers are ideal for engineers and scientists working with today’s most challenging GHz-range electronic signals. With 12-bit resolution, the PCIe digitizers offer better dynamic range than most conventional test instruments. For example, they deliver 16 times more resolution than many digital oscilloscopes, which typically use 8-bit analogue to digital converters. The extra resolution allows measurements to be made with better signal-to- noise ratio (SNR), and improved
T
he flagship digitizer series M5i by Spectrum Instrumentation now includes seven different models, offering
accuracy and precision. The front-end circuitry offers programmable full-scale ranges from ±200 mV to ±2.5 V together with variable offset. Acquisitions can be made in single-shot or multiple-waveform recording modes. To help capture the most elusive signals, a host of trigger modes are available for use on the channels or external trigger inputs. The modes include conventional edge triggering, along with more sophisticated methodssuchasWindow, Re-Arm, Or/And (logical), Software and Delay. The cards can turn almost any
PC it into a powerful measurement tool just by installing them in a suitable PCIe slot. This opens the door for anyone wishing to use the latest CPU and GPU hardware for signal processing and analysis. The new cards come with a five- year product warranty and all the tools necessary to use them in a PC running either a Windows or Linux operating system.
