class CoefficientsStruct[source]

Response structure. Fields:

  • 1 Ipart_0: float: No parameter help available

  • 2 J_0: float: float Range: -1E6 to 1E6

  • 3 I_1: float: No parameter help available

  • 4 J_1: float: float Range: -1E6 to 1E6

get() → CoefficientsStruct[source]
# [SOURce<HW>]:IQ:DOHerty:SHAPing:POLYnomial:COEFficients
value: CoefficientsStruct = driver.source.iq.doherty.shaping.polynomial.coefficients.get()

Sets the polynomial coefficients as a list of up to 10 comma separated value pairs. In Cartesian coordinates system, the coefficients bn are expressed in degrees.

Returns:

structure: for return value, see the help for CoefficientsStruct structure arguments.

get_catalog() → List[str][source]
# [SOURce<HW>]:IQ:DOHerty:SHAPing:POLYnomial:COEFficients:CATalog
value: List[str] = driver.source.iq.doherty.shaping.polynomial.coefficients.get_catalog()

Queries the available polynomial files in the default directory. Only files with the file extension dpd_poly are listed.

Returns:

catalog: string

load(filename: str) → None[source]
# [SOURce<HW>]:IQ:DOHerty:SHAPing:POLYnomial:COEFficients:LOAD
driver.source.iq.doherty.shaping.polynomial.coefficients.load(filename = 'abc')

Loads the selected polynomial file.

Parameters:

filename – string

set(ipart_0: float, j_0: float, i_1: float, j_1: float) → None[source]
# [SOURce<HW>]:IQ:DOHerty:SHAPing:POLYnomial:COEFficients
driver.source.iq.doherty.shaping.polynomial.coefficients.set(ipart_0 = 1.0, j_0 = 1.0, i_1 = 1.0, j_1 = 1.0)

Sets the polynomial coefficients as a list of up to 10 comma separated value pairs. In Cartesian coordinates system, the coefficients bn are expressed in degrees.

Parameters:

  • ipart_0 – float Range: -1E6 to 1E6

  • j_0 – float Range: -1E6 to 1E6

  • i_1 – float Range: -1E6 to 1E6

  • j_1 – float Range: -1E6 to 1E6

set_store(filename: str) → None[source]
# [SOURce<HW>]:IQ:DOHerty:SHAPing:POLYnomial:COEFficients:STORe
driver.source.iq.doherty.shaping.polynomial.coefficients.set_store(filename = 'abc')

Saves the polynomial function as polynomial file.

Parameters:

filename – string
