get_center() → float[source]
# [SOURce<HW>]:FREQuency:CENTer
value: float = driver.source.frequency.get_center()

Sets the center frequency of the sweep. The maximum value depends on the installed hardware options. For more information, refer to the specifications document.

Returns:

center: float Range: 300 kHz to depends on options, Unit: Hz

get_frequency() → float[source]
# [SOURce<HW>]:FREQuency:FREQuency
value: float = driver.source.frequency.get_frequency()

get_manual() → float[source]
# [SOURce<HW>]:FREQuency:MANual
value: float = driver.source.frequency.get_manual()

Sets the frequency and triggers a sweep step manually if SWEep:MODE MAN.

Returns:

manual: float You can select any frequency within the setting range, where: STARt is set with method RsSmw.source.frequency.start() STOP is set with method RsSmw.source.frequency.stop() OFFSet is set with method RsSmw.source.frequency.offset() Range: (STARt + OFFSet) to (STOP + OFFSet) , Unit: Hz

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

Sets the frequency mode for generating the RF output signal. The selected mode determines the parameters to be used for further frequency settings.

Returns:

mode: CW | FIXed | SWEep | LIST CW | FIXed Sets the fixed frequency mode. CW and FIXed are synonyms. The instrument operates at a defined frequency, set with command method RsSmw.source.frequency.cw.value() . SWEep Sets sweep mode. The instrument processes frequency (and level) settings in defined sweep steps. Set the range and current frequency with the commands: method RsSmw.source.frequency.start() and method RsSmw.source.frequency.stop() , method RsSmw.source.frequency.center() , method RsSmw.source.frequency.span() , method RsSmw.source.frequency.manual() LIST Sets list mode. The instrument processes frequency and level settings by means of values loaded from a list. To configure list mode settings, use the commands of the ‘SOURce:LIST subsystem’.

get_multiplier() → float[source]
# [SOURce<HW>]:FREQuency:MULTiplier
value: float = driver.source.frequency.get_multiplier()

Sets the multiplication factor NFREQ:MULT of a subsequent downstream instrument. The parameters offset fFREQ:OFFSer and multiplier NFREQ:MULT affect the frequency value set with the method RsSmw.source.frequency.cw.value() . The query method RsSmw.source.frequency.cw.value() returns the value corresponding to the formula: fFREQ = fRFout * NFREQ:MULT + fFREQ:OFFSer See ‘Displayed RF frequency and level values with downstream instruments’.

Returns:

multiplier: float Range: -10000 to 10000

get_offset() → float[source]
# [SOURce<HW>]:FREQuency:OFFSet
value: float = driver.source.frequency.get_offset()

Sets the frequency offset fFREQ:OFFSet of a downstream instrument.

The query method RsSmw.source.frequency.cw.value() returns the value corresponding to the formula: fFREQ = fRFout * NFREQ:MULT + fFREQ:OFFSer See ‘Displayed RF frequency and level values with downstream instruments’. Note: The offset also affects RF frequency sweep.
