TRIGGER_LEVEL_MDO3XXX

Set the trigger voltage of a MDO3XXX oscilloscope (or queries it). The trigger voltage is the level at which an oscilloscope will find the start of a signal. 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). trigger_volts : float The voltage to set the triggering level to. query_set : str Whether to query or set the triggering voltage. Returns: out : DataContainer Scalar: The triggering voltage.
