TRIGGER_DS1074Z

Download Flojoy Studio to try this app

Change the trigger settings for the DS1074Z oscilloscope. If 'query_set' is set to query the trigger settings will be queried and left unchanged. Requires a CONNECTION_DS1074Z 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 DS1000Z oscilloscopes Params: connection : VisaConnection The VISA address (requires the CONNECTION_DS1074Z block). query_set : select: "query" or "set" the trigger settings. channel : select Which channel to use as the trigger channel. level : float Set the triggering level, in Volts slope : select Which slope to detect the triggering time on. coupling : select Which coupling to use for the trigger signal. Returns: out : String The triggering settings.
