SIGNAL_FACTOR_DS1074Z

Download Flojoy Studio to try this app

Set the "probe" settings for the DS1074Z oscilloscope. Note that only select values are available. If the selected value isn't available, the instrument will default to 10. This setting multiplies the y axis of the selected channel by this factor. By default the setting is 10 on instrument startup. It is recommened to set it to 1 inside Flojoy, unless the probe requires a correction. 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 setting. channel : select Which channel to use. probe_factor : float Multiply the y axis by this factor. Returns: out : String The probe factor settings.
