TRIGGER_SETTINGS_MDO3XXX

Sets advanced trigger settings for an MDO3XXX oscilloscope. Note that "unchanged" will leave the settings unchanged. Requires a CONNECTION_MDO3XXX block at the start of the app to connect with the instrument. The VISA address will then be listed under 'connection'. This block should also work with compatible Tektronix scopes (untested): MDO4xxx, MSO4xxx, and DPO4xxx. Params: connection : VisaConnection The VISA address (requires the CONNECTION_MDO3XXX block). query_set : str Whether to query or set the triggering channel. edge_couplings : str Set the trigger edge coupling type. trigger_types : str Set to trigger on edge, logic, or pulses. edge_slope : str Set to trigger on positive, negative, or either slopes. Returns: out : DataContainer String: Summary of trigger settings.
