SOURce:LIST Subsystem

This subsystem contains the commands for the List mode of the instrument.

The following settings are required to operate the instrument in List mode:

  1. Create a list.

    If a list which does not exist is selected with the :LIST:SEL command, an empty list with the name of the selected list is created.

    SOURce1:LIST:SEL "New_list"

  2. Fill the list with values.

    All list components must be of the same length. This does not apply to components of length 1. This is interpreted as if the component has the same length as the other components and as if all values are the same as the first value.

    SOURce1:LIST:FREQ 100 MHz, 110 MHz, 120 MHz...

    SOURce1:LIST:POW 2dBm, -1dBm, 0dBm...

  3. Select a list.

    If a new empty file has been created with the :LIST:SEL command, this file is selected, otherwise an existing list must be selected before the List mode is activated.

    SOURce1:LIST:SEL "Old_list"

  4. Set the dwell time.

    The dwell time determines the duration of the individual list steps.

    SOURce1:LIST:DWELl 3ms

  5. Set the List mode.

    The List mode determines the way in which the list is processed. In the example the list is processed once only or repeatedly depending on the trigger setting.

    SOURce1:LIST:MODE AUTO

  6. Determine the trigger.

    In the example each trigger causes the list to be processed once from beginning to end.

    SOURce:LIST:TRIGger:SOURce SINGle

  7. Activate the List mode.

    SOURce1:FREQuency:MODE LIST

  8. Trigger the list (depending on the mode).

    SOURce1:LIST:TRIGger:EXECute

  9. Deactivate the List mode.

    SOURce1:FREQuency:MODE CW

SCPI refers to the individual lists as segments.
