Frequency Response Analyzer (FRA) is an IS technique based on Phase Sensitive Detection (PSD) to extract the real and imaginary response of the sample at each input signal, which presents advantages compared to FFT-based (Fast Fourier Transform) algorithms in terms of complexity and speed. Parallelization of this technique has proven pivotal in multi-sample characterization, reducing the instrumentation size and speeding up analysis processes in, e.g., biotechnological or chemical applications. This work presents a multichannel FRA-based IS system developed on a low-cost multicore microcontroller platform which both generates the required excitation signals and acquires and processes the output sensor data with a minimum number of external passive components, providing accurate impedance measurements. With a suitable configuration, the use of this multicore solution allows characterizing several impedance samples in parallel, reducing the measurement time. In addition, the proposed architecture is easily scalable. 000077184 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2015-65750-R 000077184 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000077184 590__ $$a2.412$$b2019 000077184 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b125 / 265 = 0.472$$c2019$$dQ2$$eT2 000077184 592__ $$a0.303$$b2019 000077184 593__ $$aElectrical and Electronic Engineering$$c2019$$dQ2 000077184 593__ $$aControl and Systems Engineering$$c2019$$dQ3 000077184 593__ $$aSignal Processing$$c2019$$dQ3 000077184 593__ $$aHardware and Architecture$$c2019$$dQ3 000077184 593__ $$aComputer Networks and Communications$$c2019$$dQ3 000077184 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000077184 700__ $$0(orcid)0000-0002-5380-3013$$aMedrano, N.$$uUniversidad de Zaragoza 000077184 700__ $$0(orcid)0000-0003-2361-1077$$aCalvo, B.$$uUniversidad de Zaragoza 000077184 700__ $$0(orcid)0000-0001-6642-3792$$aMartinez, P.A.$$uUniversidad de Zaragoza 000077184 7102_ $$15008$$2250$$aUniversidad de Zaragoza$$bDpto.
