The instrument comprises front-end acquisition boxes, receiving boxes, an Ethernet switch, and host-computer software. Each acquisition box integrates signal-conditioning circuits, a time-interleaved analog-to-digital converter, a low-jitter clock network, a field-programmable gate array (FPGA), local buffering, and an optical-fiber interface to perform high-quality acquisition, digitization, and transmission of broadband signals. A joint amplitude-phase compensation filtering algorithm is implemented in the FPGA to compensate for amplitude and phase distortions and improve the amplitude\u2013frequency response and transient waveform fidelity of the acquisition channel. Experiments demonstrate a maximum sampling rate of 10.4 GSPS, a 1\u00a0GHz operating bandwidth, an effective number of bits of at least 8.2 bits, and a dynamic range of at least 57 dB over all ranges. Within the target bandwidth, the passband flatness is within \u00b10.5 dB, the fast-edge rise time is below 350\u00a0ps, and the minimum measured synchronization time differences within one acquisition box and between different acquisition boxes are both less than one sampling period.<\/jats:p>","DOI":"10.1063\/5.0354711","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T15:39:19Z","timestamp":1792078759000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A broadband, high-dynamic-range, and high-fidelity distributed data acquisition instrument"],"prefix":"10.1063","volume":"97","author":[{"given":"Meng","family":"Wang","sequence":"first","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-9603-0882","authenticated-orcid":false,"given":"Weijia","family":"Lyu","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0910-1856","authenticated-orcid":false,"given":"Jiangjun","family":"Fan","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1839-2711","authenticated-orcid":false,"given":"Tong","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-7383-4707","authenticated-orcid":false,"given":"Zicheng","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2832-5582","authenticated-orcid":false,"given":"Hao","family":"Zeng","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China , Chengdu 611731,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,10,15]]},"reference":[{"key":"2026101511391303700_c1","doi-asserted-by":"publisher","first-page":"123508","DOI":"10.1063\/1.4772398","article-title":"A novel time stamping technique for distributed data acquisition systems","volume":"83","year":"2012","journal-title":"Rev.
