“…In addition, it is assumed that the digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) used for data acquisition are calibrated prior to their in the tuning of the relevant RF devices. Methods for loopback testing of DACs and ADCs are described in [20].…”

“…However, if parallel testing of multiple component-pairs is desirable, multiple loopback elements, one for each of the component-pair, would be needed on the load board. The loopback elements for parallel loopback testing could be minimized by including an analog summer and an RMS detector which are shared by multiple component-pairs 111) . By analyzing the test responses at the outputs of these shared elements with respect to different test stimuli, the performance of an individual data converter can be derived.…”

“…Θα πρέπει να σημειωθεί πως, τόσο ο έλεγχος, όσο και η βαθμονόμηση του ενσωματωμένου ADC θα πρέπει να έχει προηγηθεί της χρήσης του για τον έλεγχο του μίκτη, πράγμα που ισχύει και για το κύκλωμα του ενσωματωμένου DSP. Μέθοδοι για τον έλεγχο των ADCs με την τεχνική του βρόχου επιστροφής (loopback) έχουν ήδη προταθεί στη βιβλιογραφία[147]. Επιπλέον, το κύκλωμα του DSP μπορεί να ελεγχθεί μέσω ψηφιακών τεχνικών ελέγχου προκειμένου να επιβεβαιωθεί η ορθή λειτουργία του.…”
