Awgn commands group definition. 22 total commands, 5 Subgroups, 5 group commands

get_brate() → float[source]

# SCPI: [SOURce<HW>]:AWGN:BRATe
value: float = driver.source.awgn.get_brate()

Sets the bit rate used for calculation of bit energy to noise power ratio. Valid units are bps, kbps and mabps as well as b/s, kb/s and mab/s.

return:

brate: float Range: 400 to depends on the installed options

get_cn_ratio() → float[source]

# SCPI: [SOURce<HW>]:AWGN:CNRatio
value: float = driver.source.awgn.get_cn_ratio()

Sets the carrier/interferer ratio.

return:

cn_ratio: float Range: -50 to 45

get_en_ratio() → float[source]

# SCPI: [SOURce<HW>]:AWGN:ENRatio
value: float = driver.source.awgn.get_en_ratio()

Sets the ratio of bit energy to noise power density.

return:

en_ratio: float Range: -50 to depends on the installed options, Unit: dB

get_mode() → NoisAwgnMode[source]

# SCPI: [SOURce<HW>]:AWGN:MODE
value: enums.NoisAwgnMode = driver.source.awgn.get_mode()

Determines how the interfering signal is generated.

return:

mode: ONLY| ADD| CW ADD The AWGN noise signal is added to the baseband signal. ONLY The pure AWGN noise signal is modulated to the carrier. The connection to the baseband is interrupted CW The sine interfering signal is added to the baseband signal.

get_state() → bool[source]

# SCPI: [SOURce<HW>]:AWGN:STATe
value: bool = driver.source.awgn.get_state()

Activates or deactivates the AWGN generator or the corresponding stream. See also ‘Suffixes in the keywords ENTity<ch> and SOURce<hw>’.

return:

state: 1| ON| 0| OFF

set_brate(brate: float) → None[source]

# SCPI: [SOURce<HW>]:AWGN:BRATe
driver.source.awgn.set_brate(brate = 1.0)

Sets the bit rate used for calculation of bit energy to noise power ratio. Valid units are bps, kbps and mabps as well as b/s, kb/s and mab/s.

param brate:

float Range: 400 to depends on the installed options

set_cn_ratio(cn_ratio: float) → None[source]

# SCPI: [SOURce<HW>]:AWGN:CNRatio
driver.source.awgn.set_cn_ratio(cn_ratio = 1.0)

Sets the carrier/interferer ratio.

param cn_ratio:

float Range: -50 to 45

set_en_ratio(en_ratio: float) → None[source]

# SCPI: [SOURce<HW>]:AWGN:ENRatio
driver.source.awgn.set_en_ratio(en_ratio = 1.0)

Sets the ratio of bit energy to noise power density.

param en_ratio:

float Range: -50 to depends on the installed options, Unit: dB

set_mode(mode: NoisAwgnMode) → None[source]

# SCPI: [SOURce<HW>]:AWGN:MODE
driver.source.awgn.set_mode(mode = enums.NoisAwgnMode.ADD)

Determines how the interfering signal is generated.

param mode:

ONLY| ADD| CW ADD The AWGN noise signal is added to the baseband signal. ONLY The pure AWGN noise signal is modulated to the carrier. The connection to the baseband is interrupted CW The sine interfering signal is added to the baseband signal.

set_state(state: bool) → None[source]

# SCPI: [SOURce<HW>]:AWGN:STATe
driver.source.awgn.set_state(state = False)

Activates or deactivates the AWGN generator or the corresponding stream. See also ‘Suffixes in the keywords ENTity<ch> and SOURce<hw>’.

param state:

1| ON| 0| OFF
