get_crest_factor() → float[source]
# [SOURce<HW>]:IQ:CREStfactor
value: float = driver.source.iq.get_crest_factor()

Specifies the crest factor for the external analog signal.

Returns:

crest_factor: float Range: 0 to 35, Unit: dB

get_gain() → IqGain[source]
# [SOURce<HW>]:IQ:GAIN
value: enums.IqGain = driver.source.iq.get_gain()

Optimizes the modulation of the I/Q modulator for a subset of measurement requirement.

get_source() → IqMode[source]
# [SOURce<HW>]:IQ:SOURce
value: enums.IqMode = driver.source.iq.get_source()

Selects the input signal source for the I/Q modulator.

Returns:

source: BASeband | ANALog External signals disable the amplitude modulation, an enabled custom digital modulation, any configured digital standard or an applied digital baseband input signal.

get_state() → bool[source]
# [SOURce<HW>]:IQ:STATe
value: bool = driver.source.iq.get_state()

Enables/disables the I/Q modulation. Note: Interdependencies The following functions cannot be activated simultaneously. They deactivate each other.

  • The internal baseband generator ([:SOURce<hw>]:BB:<DigStd>:STATe) and the external digital baseband input (method RsSmbv.source.bbin.state() )

  • The external digital baseband input (method RsSmbv.source.bbin.state() ) and digital output (method RsSmbv.source.iq.output.digital.state() ) because they share the same physical connectors (Dig I/Q and the HS Dig I/Q) .

  • The digital output (method RsSmbv.source.iq.output.digital.state() ) and the output of analog I/Q signals:

  • If [:SOURce<hw>]:IQ:SOURce BASeband, method RsSmbv.source.iq.state() + OUTPut<hw>:STATe or

  • method RsSmbv.source.iq.output.analog.state()

Returns:

state: 1 | ON | 0| OFF

get_wb_state() → bool[source]
# [SOURce<HW>]:IQ:WBSTate
value: bool = driver.source.iq.get_wb_state()

Activates I/Q wideband mode. Activation automatically optimizes the settings for wideband modulation signals with a bandwidth that is higher then 5 MHz.

Returns:

wb_state: 1 | ON | 0| OFF *RST: 0 (R&S SMBVB-K524) / 1 (R&S SMBVB-K525)

set_crest_factor(crest_factor: float) → None[source]
# [SOURce<HW>]:IQ:CREStfactor
driver.source.iq.set_crest_factor(crest_factor = 1.0)

Specifies the crest factor for the external analog signal.

Parameters:

crest_factor – float Range: 0 to 35, Unit: dB

set_gain(gain: IqGain) → None[source]
# [SOURce<HW>]:IQ:GAIN
driver.source.iq.set_gain(gain = enums.IqGain.DB0)

Optimizes the modulation of the I/Q modulator for a subset of measurement requirement.

Parameters:

gain – DBM4 | DBM2 | DB0 | DB2 | DB4 | DB8 | DB6 Dynamic range of 16 dB divided into 2 dB steps. DB0 | DB2 | DB4 | DB6 | DB8 Activates the specified gain of 0 dB, +2 dB, +4 dB, +6 dB, +8 dB DBM2 | DBM4 Activates the specified gain of -2 dB, -4 dB

set_source(source: IqMode) → None[source]
# [SOURce<HW>]:IQ:SOURce
driver.source.iq.set_source(source = enums.IqMode.ANALog)

Selects the input signal source for the I/Q modulator.

Parameters:

source – BASeband | ANALog External signals disable the amplitude modulation, an enabled custom digital modulation, any configured digital standard or an applied digital baseband input signal.

set_state(state: bool) → None[source]
# [SOURce<HW>]:IQ:STATe
driver.source.iq.set_state(state = False)

Enables/disables the I/Q modulation. Note: Interdependencies The following functions cannot be activated simultaneously. They deactivate each other.

  • The internal baseband generator ([:SOURce<hw>]:BB:<DigStd>:STATe) and the external digital baseband input (method RsSmbv.source.bbin.state() )

  • The external digital baseband input (method RsSmbv.source.bbin.state() ) and digital output (method RsSmbv.source.iq.output.digital.state() ) because they share the same physical connectors (Dig I/Q and the HS Dig I/Q) .

  • The digital output (method RsSmbv.source.iq.output.digital.state() ) and the output of analog I/Q signals:

  • If [:SOURce<hw>]:IQ:SOURce BASeband, method RsSmbv.source.iq.state() + OUTPut<hw>:STATe or

  • method RsSmbv.source.iq.output.analog.state()

Parameters:

state – 1 | ON | 0| OFF

set_wb_state(wb_state: bool) → None[source]
# [SOURce<HW>]:IQ:WBSTate
driver.source.iq.set_wb_state(wb_state = False)

Activates I/Q wideband mode. Activation automatically optimizes the settings for wideband modulation signals with a bandwidth that is higher then 5 MHz.

Parameters:

wb_state – 1 | ON | 0| OFF *RST: 0 (R&S SMBVB-K524) / 1 (R&S SMBVB-K525)
