Spectrum Instruments Enhances Flagship Digitizer with New Streaming Mode
Spectrum Instruments recently announced the addition of a streaming mode to their M5i.33xx digitizer, solidifying its position as the industry leader. This new feature allows for continuous data collection, streaming, and analysis at impressive sampling rates of up to 10 GS/s. By utilizing commercial off-the-shelf (COTS) PC technology, such as GPU and SSD arrays, the M5i.33xx can store streaming data for extended periods, making it an ideal choice for applications requiring continuous signal processing.
The M5i.33xx digitizer family boasts a wide range of options, with sampling rates ranging from 3.2 to 10 GS/s, 12-bit vertical resolution, and bandwidth from 1 to 4.7 GHz. Additionally, it is equipped with a Gen3 PCIe 16 lane bus, enabling lightning-fast data transfer speeds of up to 12.8GB/s.
With this impressive transfer rate, the M5i.33xx digitizer can directly stream data collected at a sampling rate of 6.4 GS/s on one channel or 3.2 GS/s on two channels to a PC environment without any loss of information. For applications requiring even faster sampling rates, a special 8-bit transfer mode can be added, allowing data to be streamed at up to 10 GS/s on one channel or 5 GS/s on two channels.
The M5i.33xx utilizes Spectrum’s CUDA Access for Parallel Processing (SCAPP) for scenarios that demand intensive signal processing and streaming. This software package transfers data collected by the RDMA process directly from the digitizer to a commercial GPU based on the NVIDIA CUDA standard. The GPU’s numerous processing cores (up to 10,000) and vast memory (up to 48GB) can then be utilized for instant parallel processing, offering users unparalleled processing power.
SCAPP provides a comprehensive set of CUDA parallel processing routines and examples for various interactions between digitizers and GPUs, including digital down conversion, filtering, signal averaging, data demultiplexing, data transformation, and fast Fourier transform (FFT). These routines serve as building blocks for implementing similar processing functions, and they are designed to be user-friendly, with support for C/C++ and Python programming languages.
One noteworthy application of the M5i.33xx digitizer, combined with SCAPP and an affordable GPU, is continuous spectral analysis. By collecting time domain data at 10 GS/s and streaming it directly to the GPU for continuous conversion to the frequency domain, users can achieve continuous conversion and analysis of signals. The system can effortlessly handle processes like multiplexing, windowing, FFT, and averaging (1M FFT blocks), providing a frequency resolution of 10 kHz over the entire frequency range from DC to 5 GHz. For even better resolution, larger FFT blocks can be utilized.
To complement their streaming and data storage capabilities, Spectrum Instruments offers a system based on Supermicro servers equipped with AMD EPYC processors and RAID storage using U.2 SSD. This commercial off-the-shelf (COTS) system boasts up to 240TB of storage, enabling the recording of more than 6 hours of data at a sampling rate of up to 10GS/s.
Oliver Robini, CTO of Spectrum Instruments, highlighted the diverse applications of GPUs and storage systems in various industries such as imaging, communications, astronomy, spectroscopy, and aerospace. He emphasized that Spectrum Instruments provides a unique and differentiated tool for users who monitor signals, whether for short or long periods of time.
The M5i.33xx series of digitizers and streaming systems is currently available, with the new 8-bit transfer mode included on all M5i digitizer cards. For more detailed information, please visit the Spectrum Instruments website.
Spectrum Instruments announced on the 4th that it will add a streaming mode to its flagship digitizer, the M5i.33xx.
It can continuously collect, stream and analyze data at sampling rates up to 10 GS/s, and when used with COTS (commercial) PC technology such as GPU and SSD arrays for continuous signal processing, streaming data can be stored for long periods of time A system can be built.
The M5i.33xx digitizer family includes seven models, offering sampling rates from 3.2 to 10 GS/s, 12-bit vertical resolution, and bandwidth from 1 to 4.7 GHz. It also has a Gen3 PCIe 16 lane bus, which transfers data at speeds of up to 12.8GB/s.
This industry-leading transfer rate supports streaming data collected at a sampling rate of 6.4 GS/s on one channel or 3.2 GS/s on two channels directly to a PC environment without loss of information. If faster sampling rates are required, a special 8-bit transfer mode can be added to stream acquired data up to 10 GS/s on one channel or 5 GS/s on two channels.
The M5i.33xx uses SCAPP (Spectrum’s CUDA Access for Parallel Processing) in situations that require intensive signal processing and streaming. The SCAPP software package transfers data collected by the RDMA process directly from the digitizer to a commercial GPU based on the NVIDIA CUDA standard. Users can then take advantage of the GPU’s multiple processing cores (up to 10,000) and large memory (up to 48GB) for instant parallel processing.
SCAPP contains CUDA parallel processing routines and examples for interaction between digitizers and GPUs, including digital down conversion (DDC), filtering, signal averaging, data demultiplexing, data transformation, or fast Fourier transform (FFT). provides easy building blocks for similar processing functions.
All SCAPP software is based on C/C++ and Python, making it easy to implement and modify using only general programming skills. For example, if continuous spectral analysis is required, time domain data can be collected at 10 GS/s and streamed directly to the GPU for continuous conversion to the frequency domain.
A system with an M5i.33xx digitizer (new 8-bit mode switching), SCAPP, and an affordable GPU allows conversion processes such as multiplexing, windowing, FFT, and averaging (1M FFT blocks) to run continuously. This FFT covers the frequency range from DC to 5 GHz at a sampling rate of 10 GS/s and provides a frequency resolution of 10 kHz. Better resolution can also be produced by using larger FFT blocks.
Spectrum Instruments provides a streaming and data storage system based on Supermicro servers equipped with AMD EPYC processors and RAID storage using U.2 SSD. This COTS system has up to 240TB of storage and can record more than 6 hours of data at a sampling rate of up to 10GS/s.
“GPUs provide a solution for dealing with intensive situations such as those commonly found in imaging, communications, astronomy, spectroscopy and aerospace, while storage systems are associated with quality control, mapping or surveillance tasks,” says Oliver Robini, CTO of Spectrum Instruments. We provide a differentiated tool for all users who monitor signals for a short period or for a long period of time,” he emphasized.
The M5i.33xx series of digitizers and streaming systems is now available, and the new 8-bit transfer mode is included on all M5i digitizer cards. More detailed information is available on the website.
