SyncMode or SM [DISABLE|START|SAMPLE]
• Default parameter: DISABLE

processing module includes a sync input line (SyncIn) to allow external hardware control of
ADV data collection.
○
DISABLE indicates that data collection is completely under internal software control.
○
START indicates that data collection starts with the rising edge of the first input sync
pulse and continues at the software-programmed sampling rate.
○
SAMPLE indicates that data collection starts with the rising edge of the first input sync
pulse and continues at a rate determined by the time between the rising edge of succes-
sive input sync pulses.
• See §5.5 for information about external synchronization.
