In order to prevent interference from the 50 or 60 Hz mains line the CAT can optionally trigger QMatrix acquisition on the external SYNC input signal. The SYNC signal should be derived from the mains line and the acquisition will trigger on a falling edge of this signal. The SYNC pin option can be used with any of the QMatrix modes discussed in the previous sections. The SYNC pin usage in the Internal Discharge mode scenario is shown in case F.
For QMatrix method SMP, DIS, VDIV and SYNC pin options discussed in this Section, Refer to general_pin_options_t.
