get_dwell() → float[source]
# [SOURce<HW>]:SWEep:[FREQuency]:DWELl
value: float = driver.source.sweep.frequency.get_dwell()

Sets the dwell time for a frequency sweep step.

Returns:

dwell: float Range: 0.001 to 100

get_mode() → AutoManStep[source]
# [SOURce<HW>]:SWEep:[FREQuency]:MODE
value: enums.AutoManStep = driver.source.sweep.frequency.get_mode()

Sets the cycle mode for the frequency sweep.

Returns:

mode: AUTO | MANual | STEP AUTO Each trigger event triggers exactly one complete sweep. MANual The trigger system is not active. You can trigger every step individually by input of the frequencies with the method RsSmw.source.frequency.manual() . STEP Each trigger event triggers one sweep step. The frequency increases by the value entered with method RsSmw.source.sweep.frequency.step.linear() (linear spacing) or method RsSmw.source.sweep.frequency.step.logarithmic() (logarithmic spacing) .

get_points() → int[source]
# [SOURce<HW>]:SWEep:[FREQuency]:POINts
value: int = driver.source.sweep.frequency.get_points()

Sets the number of steps within the RF frequency sweep range. Two separate POINts values are used for linear or logarithmic sweep spacing. This command always affects the currently set sweep spacing that you can set via the following command: SOURce<hw>:SWEep:FREQuency:SPACing LINear | LOGarithmic

Returns:

points: integer Range: 2 to Max

get_retrace() → bool[source]
# [SOURce<HW>]:SWEep:[FREQuency]:RETRace
value: bool = driver.source.sweep.frequency.get_retrace()

Activates that the signal changes to the start frequency value while it is waiting for the next trigger event. You can enable this feature, when you are working with sawtooth shapes in sweep mode ‘Single’ or ‘External Single’.

Returns:

state: 1 | ON | 0| OFF

get_running() → bool[source]
# [SOURce<HW>]:SWEep:[FREQuency]:RUNNing
value: bool = driver.source.sweep.frequency.get_running()

Queries the current sweep state.

Returns:

state: 1 | ON | 0| OFF

get_shape() → SweCyclMode[source]
# [SOURce<HW>]:SWEep:[FREQuency]:SHAPe
value: enums.SweCyclMode = driver.source.sweep.frequency.get_shape()

Determines the waveform shape for a frequency sweep sequence.

Returns:

shape: SAWTooth | TRIangle

get_spacing() → Spacing[source]
# [SOURce<HW>]:SWEep:[FREQuency]:SPACing
value: enums.Spacing = driver.source.sweep.frequency.get_spacing()

Selects the mode for the calculation of the frequency intervals, with which the current frequency at each step is increased or decreased. The keyword [:FREQuency] can be omitted; then the command is SCPI-compliant.

Returns:

spacing: LINear | LOGarithmic LINear Sets a fixed frequency value as step width and adds it to the current frequency. The linear step width is entered in Hz, see method RsSmw.source.sweep.frequency.step.linear() . LOGarithmic Sets a constant fraction of the current frequency as step width and adds it to the current frequency. The logarithmic step width is entered in %, see method RsSmw.source.sweep.frequency.step.logarithmic() .

set_dwell(dwell: float) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:DWELl
driver.source.sweep.frequency.set_dwell(dwell = 1.0)

Sets the dwell time for a frequency sweep step.

Parameters:

dwell – float Range: 0.001 to 100

set_mode(mode: AutoManStep) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:MODE
driver.source.sweep.frequency.set_mode(mode = enums.AutoManStep.AUTO)

Sets the cycle mode for the frequency sweep.

Parameters:

mode – AUTO | MANual | STEP AUTO Each trigger event triggers exactly one complete sweep. MANual The trigger system is not active. You can trigger every step individually by input of the frequencies with the method RsSmw.source.frequency.manual() . STEP Each trigger event triggers one sweep step. The frequency increases by the value entered with method RsSmw.source.sweep.frequency.step.linear() (linear spacing) or method RsSmw.source.sweep.frequency.step.logarithmic() (logarithmic spacing) .

set_points(points: int) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:POINts
driver.source.sweep.frequency.set_points(points = 1)

Sets the number of steps within the RF frequency sweep range. Two separate POINts values are used for linear or logarithmic sweep spacing. This command always affects the currently set sweep spacing that you can set via the following command: SOURce<hw>:SWEep:FREQuency:SPACing LINear | LOGarithmic

Parameters:

points – integer Range: 2 to Max

set_retrace(state: bool) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:RETRace
driver.source.sweep.frequency.set_retrace(state = False)

Activates that the signal changes to the start frequency value while it is waiting for the next trigger event. You can enable this feature, when you are working with sawtooth shapes in sweep mode ‘Single’ or ‘External Single’.

Parameters:

state – 1 | ON | 0| OFF

set_shape(shape: SweCyclMode) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:SHAPe
driver.source.sweep.frequency.set_shape(shape = enums.SweCyclMode.SAWTooth)

Determines the waveform shape for a frequency sweep sequence.

Parameters:

shape – SAWTooth | TRIangle

set_spacing(spacing: Spacing) → None[source]
# [SOURce<HW>]:SWEep:[FREQuency]:SPACing
driver.source.sweep.frequency.set_spacing(spacing = enums.Spacing.LINear)

Selects the mode for the calculation of the frequency intervals, with which the current frequency at each step is increased or decreased. The keyword [:FREQuency] can be omitted; then the command is SCPI-compliant.

Parameters:

spacing – LINear | LOGarithmic LINear Sets a fixed frequency value as step width and adds it to the current frequency. The linear step width is entered in Hz, see method RsSmw.source.sweep.frequency.step.linear() . LOGarithmic Sets a constant fraction of the current frequency as step width and adds it to the current frequency. The logarithmic step width is entered in %, see method RsSmw.source.sweep.frequency.step.logarithmic() .
