Spectrum Instrumentation has added a GPU-based digital down-conversion (DDC) option to its PC-based ‘SCAPP’ software, used with its PCIe signal digitiser cards – effectively ADCs for PCs. Working with sufficiently-powerful Cuda-based GPUs, the DDC option allows on-the-fly baseband signal extraction, and is offered as an alternative to FPGA-based DDC and its associated programming. “The GPU, …
