VERTICAL_AXIS_DS1074Z

Download Flojoy Studio to try this app
Change the vertical axis display for the DS1074Z oscilloscope. Both the scale and offset can be changed. The scale sets the size of one section. The full window is 12 times the scale. The offset and scale setting will be rounded up to the nearest available setting by the DS1074Z. 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 set or query. offset : float Set the vertical axis offset. scale : float Set the vertical axis scale. Returns: out : String Summary of the vertical axis settings.
