DIGITAL_ON_OFF_DS1074Z

The DIGITAL_ON_OFF_DS1074Z node turns digital channels on or off for the DS1074Z. Requires a CONNECTION_DS1074Z node at the start of the app to connect with the instrument. The VISA address will then be listed under 'connection'. This node should also work with compatible DS1000Z oscilloscopes Params: connection : VisaConnection The VISA address (requires the CONNECTION_DS1074Z node). digi_on_off : select Turn digital channel (i.e. LA) on the scope on or off. d0 : select Turn digital channel 0 on or off. d1 : select Turn digital channel 1 on or off. d2 : select Turn digital channel 2 on or off. d3 : select Turn digital channel 3 on or off. use_pods : select Use pod1 and pod2 parameters? If True, d0-d3 parameters are not used. pod1 : select Turn digital channels 0-7 on or off. pod2 : select Turn digital channels 8-15 on or off. Returns: out : DataContainer TextBlob: summary of channel settings.

In this example the digital function blocks are used to control the LA channels of the Rigol DS1047Z oscilloscope.

A CONNECTION_DS1047Z block must first be used to make the connection between Flojoy and the instrument.

The DIGITAL_ON_OFF_DS1047Z block turns the LA digital channel off as well as indiviual sub-channels.

The DIGITAL_TRIGGER_DS1047Z block chooses the triggering digital channel (e.g. D0 here) and the triggering level.

The SINGLE_TRIGGER_DS1047Z block sets the triggering mode to single which stops the oscilloscope as soon as a triggering signal is detected, leaving a static trace on the screen.

The DIGITAL_TRACE_DS1047Z block extracts traces from digital channels such as D0.
