get(generatorIx=GeneratorIx.Default) → float[source]

# [SOURce<HW>]:FM<CH>:[DEViation]
value: float = driver.source.fm.deviation.get(generatorIx = repcap.GeneratorIx.Default)

Sets the modulation deviation of the frequency modulation in Hz.

Parameters:: generatorIx – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Fm’)
Returns:: deviation: float The maximum deviation depends on the RF frequency and the selected modulation mode (see the specifiacton document) . Range: 0 to max

get_mode() → ModulationDevMode[source]

# [SOURce<HW>]:FM:DEViation:MODE
value: enums.ModulationDevMode = driver.source.fm.deviation.get_mode()

Selects the coupling mode. The coupling mode parameter also determines the mode for fixing the total deviation.

Returns:: fm_dev_mode: UNCoupled | TOTal | RATio UNCoupled Does not couple the LF signals. The deviation values of both paths are independent. TOTal Couples the deviation of both paths. RATio Couples the deviation ratio of both paths

get_sum() → float[source]

# [SOURce<HW>]:FM:DEViation:SUM
value: float = driver.source.fm.deviation.get_sum()

Sets the total deviation of the LF signal when using combined signal sources in frequency modulation.

set(deviation: float, generatorIx=GeneratorIx.Default) → None[source]

# [SOURce<HW>]:FM<CH>:[DEViation]
driver.source.fm.deviation.set(deviation = 1.0, generatorIx = repcap.GeneratorIx.Default)

Sets the modulation deviation of the frequency modulation in Hz.

Parameters:

deviation – float The maximum deviation depends on the RF frequency and the selected modulation mode (see the specifiacton document) . Range: 0 to max
generatorIx – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Fm’)

set_mode(fm_dev_mode: ModulationDevMode) → None[source]

# [SOURce<HW>]:FM:DEViation:MODE
driver.source.fm.deviation.set_mode(fm_dev_mode = enums.ModulationDevMode.RATio)

Selects the coupling mode. The coupling mode parameter also determines the mode for fixing the total deviation.

Parameters:: fm_dev_mode – UNCoupled | TOTal | RATio UNCoupled Does not couple the LF signals. The deviation values of both paths are independent. TOTal Couples the deviation of both paths. RATio Couples the deviation ratio of both paths

set_sum(fm_dev_sum: float) → None[source]

# [SOURce<HW>]:FM:DEViation:SUM
driver.source.fm.deviation.set_sum(fm_dev_sum = 1.0)

Sets the total deviation of the LF signal when using combined signal sources in frequency modulation.
