:LIST Subsystem

The list subsystem is used to set the controls and the parameters associated with

frequency and/or power sweeps.

Dwell List

:LIST:DWELl <val>{, <val>}

:LIST:DWELl?

This command defines a list of dwell times. The list is stored in a file (DWEL_FILE) which

is only reinitialized upon power-up preset. Each value specifies the minimum time that the

sweep engine waits at that point’s frequency and/or power setting before going to the next

setting. Dwell times are only used when the point trigger source is set to Immediate.

Dwell List Points Query

:LIST:DWELl:POINts?

This command queries the signal generator for the number of points in the dwell list.

Dwell List Type

:LIST:DWELl:TYPE LIST|STEP

:LIST:DWELl:TYPE?

This command sets the type of dwell for a list sweep. The choices are List or Step. Use this

command to toggle the dwell time for the list sweep points between the values defined in

the list sweep and the value set for step sweep. Choose

LIST to sweep with dwell times that

you have defined in the list sweep. Choose

STEP to sweep each point in the list with a dwell

time set via the :SWEep:DWELl <val> command.

*RST Value: List

Frequency List

:LIST:FREQuency <val>{, <val>}

:LIST:FREQuency?

This command defines the frequency list. Each value specifies the frequency that the

sweep engine uses when sweeping frequency. This list is stored in a file (FREQ_FILE),

which is only

reinitialized upon power-up preset.

Frequency List Points Query

:LIST:FREQuency:POINts?

This command queries the signal generator for the number of points in the frequency list.
