property sweep_time_interval: Any: Control the sweep time interval (int from 0 to 99999 s).

property transfer_format: Any: Control the data transfer format. It returns to default ASCII at reset.

trigger(): Perform a single sweep according to previous conditions.

wait_for_sweep_complete(should_stop=<function AQ6370Series.<lambda>>, timeout=3600, delay=0)

Block the program, waiting for the sweep to complete.

Parameters:
