摘要

Data-acquisition systems (DAS) set the fidelity of industrial radiotracer measurements, yet side-by-side benchmarks are scarce. We evaluate three multi-channel DAS LUDLUM, ALTAIX/ASHTAR, and KAERI on field datasets using a unified pipeline (SNR, FWHM, AUC, centroid, Δt, PSD,). LUDLUM delivered the narrowest pulses (mean FWHM ≈32 s) and earliest centroids (108 s), enabling superior timing/Δt. ALTAIX achieved the highest mean SNR (≈543) and larger AUC, indicating stronger sensitivity. KAERI showed ultra-low mid-band noise; after baseline/time-base harmonization its effective SNR was ≈715, though raw timing is not directly comparable. We also assess power-loss robustness and propose design guidance; timing tasks favor LUDLUM, amplitude-limited tasks favor ALTAIX.
