class OfdmCls

Ofdm commands group definition. 4 total commands, 0 Subgroups, 4 group commands

get_alpha() → NumbersB

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:ALPHa
value: enums.NumbersB = driver.source.bb.dvb.dvbt.ofdm.get_alpha()

Selects the alpha value. This value is used to shape the constellation of the modulation. For DVB-H, this value is always 1.

return:

alpha: 1| 2| 4

get_bandwidth() → DvbSysBand

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:BWIDth
value: enums.DvbSysBand = driver.source.bb.dvb.dvbt.ofdm.get_bandwidth()

Selects the system bandwidth.

return:

bwidth: 5| 6| 7| 8

get_ginterval() → DvbGuardInt

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:GINTerval
value: enums.DvbGuardInt = driver.source.bb.dvb.dvbt.ofdm.get_ginterval()

Selects the OFDM/RF guard interval.

return:

ginterval: GI1D4| GI1D8| GI1D16| GI1D32

get_modulation() → ModulationC

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:MODulation
value: enums.ModulationC = driver.source.bb.dvb.dvbt.ofdm.get_modulation()

Selects the constellation for the OFDM modulation.

return:

modulation: QPSK| QAM16| QAM64

set_alpha(alpha: NumbersB) → None

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:ALPHa
driver.source.bb.dvb.dvbt.ofdm.set_alpha(alpha = enums.NumbersB._1)

Selects the alpha value. This value is used to shape the constellation of the modulation. For DVB-H, this value is always 1.

param alpha:

1| 2| 4

set_bandwidth(bwidth: DvbSysBand) → None

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:BWIDth
driver.source.bb.dvb.dvbt.ofdm.set_bandwidth(bwidth = enums.DvbSysBand._5)

Selects the system bandwidth.

param bwidth:

5| 6| 7| 8

set_ginterval(ginterval: DvbGuardInt) → None

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:GINTerval
driver.source.bb.dvb.dvbt.ofdm.set_ginterval(ginterval = enums.DvbGuardInt.GI1D16)

Selects the OFDM/RF guard interval.

param ginterval:

GI1D4| GI1D8| GI1D16| GI1D32

set_modulation(modulation: ModulationC) → None

# SCPI: [SOURce<HW>]:BB:DVB:DVBT:OFDM:MODulation
driver.source.bb.dvb.dvbt.ofdm.set_modulation(modulation = enums.ModulationC.QAM16)

Selects the constellation for the OFDM modulation.

param modulation:

QPSK| QAM16| QAM64
