Guzik's ADC 6000 series of AXIe modules bring high-speed signal capture to the up-and-coming AXIe instrumentation bus. Available in one-channel to four-channel models, the ADC 6000 series has a maximum bandwidth of 13 GHz with sampling to 40 Gsamples/s (one channel model). Other models have bandwidths of 4 GHz, 6.5 GHz, and 8 GHz with samples rates of 10 Gsamples/s and 20 Gsamples/s. In addition to high speed and bandwidth, the ADC 6000 modules have deep memory, ranging from 2 Gbytes to 16 Gbytes for the four-channel model and from 8 Gbytes to 64 Gbytes for the one-channel model. The digitizer modules can be interleaved to double the sample rate.
High-speed digitizing of analog signals is only half the battle. The rest comes in getting digitized signals to a processor or host computer and in processing the data to get the right information. To accomplish that, the ADC 6000 models use a four-lane cabled PCI Express Gen 4 link, which delivers 1.6 Gbytes/s of sustained transfer rate to a host computer (the host needs PCIe bridge card). Even with such high sustained data rates, the module need not send all the data to a host computer, because it can process the data with its onboard FPGA. Signal-processing functions include channel equalization, filtering, FFT, DFT, min/max, averaging, and parameter calculations. In addition, Guzik can provide custom signal-processing functions.
If you use a host computer for signal processing, you can use your computer's graphic hardware. Guzik provides computing algorithms for the NVidia GeForce GTX 5703 GPU (graphics processing unit), which lets you use any Nvidia GPU with computing capability 2.0 or higher.
The ADC 6000 modules have a digital hardware trigger capability that lets you define trigger conditions for capturing the right signals. It also has external triggers and clocks for synchronizing signal acquisition to external equipment and for system integration.
Software support includes a development kit for custom applications. Guzik also provides a stand-alone program for instrument setup and display purposes. The software lets you export digitized signals for use with Excel, Matlab, and other data-processing applications.
