The system requires low-frequency voltage control that is high-precision and low-noise, which they currently get from an external unit containing digital-to-analog converters (DACs). The Clinic team is developing a low-cost, open-source, multi-channel alternative to the current HRL system to integrate DAC control directly onto the FPGA so that it performs measurements and calibrations more efficiently and with better timing control than previously possible.\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>HRL Laboratories Engineering, 2024\u201325 Liaison(s): Abbie Wessels, Andrew Oriani, Paul Jerger \u201915 Advisor(s): Joshua Brake Students(s): Zoe Worrall (TL-S), Ellie [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[164],"tags":[249],"class_list":["post-14495","post","type-post","status-publish","format-standard","hentry","category-engineering","tag-hrl-laboratories"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts\/14495","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/comments?post=14495"}],"version-history":[{"count":1,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts\/14495\/revisions"}],"predecessor-version":[{"id":14540,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts\/14495\/revisions\/14540"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/media?parent=14495"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/categories?post=14495"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/tags?post=14495"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
