# SCPI: [SOURce<HW>]:BB:NR5G:HFB:BASeband
value: int = driver.source.bb.nr5G.hfb.get_baseband()

In serial mode, required for multiplexing serial commands for different basebands to one feedback line. See also Example ‘Configuring the ‘Baseband Selector’ for the 2 Tx antenna ports test cases’.

return:

fb_baseband: integer Range: 0 to 3

get_connector() → FeedbackConnectorAll[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:CONNector
value: enums.FeedbackConnectorAll = driver.source.bb.nr5G.hfb.get_connector()

Sets the feedback line connector.

return:

fb_connector: LOCal LOCal T/M 3 connector

get_cs_rate() → int[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:CSRate
value: int = driver.source.bb.nr5G.hfb.get_cs_rate()

Defines a custom serial rate.

INTRO_CMD_HELP: Prerequisites for this command

Select a custom serial rate ([:SOURce<hw>]:BB:NR5G:HFB:SRATe) .

If you have defined one of the predefined serial rates, the command queries the selected serial rate.

return:

custom_ser_rate: No help available

get_delay() → float[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:DELay
value: float = driver.source.bb.nr5G.hfb.get_delay()

Sets the point in time when the feedback can be sent to the instrument.

return:

fb_user_delay: float Range: -20 to -1.0

get_hpn_mode() → bool[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:HPNMode
value: bool = driver.source.bb.nr5G.hfb.get_hpn_mode()

Enables or disables the HARQ process number (HPN) mode. When the ‘HPN Mode’ is set to active, the additional user delay is set to -1.00 Slots and made unchangeable. An additional ‘HARQ Process Number’parameter is accessible in the PUSCH settings (‘PDSCH and PUSCH scheduling commands’) .

return:

hpn_mode: 1| ON| 0| OFF

get_log_path() → str[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:LOGPath
value: str = driver.source.bb.nr5G.hfb.get_log_path()

Defines the output folder on the device for the log files.

return:

log_gen_output_path: string

get_log_state() → bool[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:LOGState
value: bool = driver.source.bb.nr5G.hfb.get_log_state()

Enables the R&S SMW200A to create and store debug reports, i.e. log files with detailed information on the real-time feedback.

INTRO_CMD_HELP: The instrument generates two types of reports:

Transmission report

Table Header:

This file contains information about what is sent (e.g. redundancy versions) during the first 100 slots after triggering.

File is created after the 100 slots are sent.

Reception report

Table Header:

This file contains information about the first 100 received serial commands.

File is created after 100 commands are successfully received.

Use these debug files for troubleshooting of complex real-time feedback tests.

return:

log_gen_state: 1| ON| 0| OFF

get_mode() → FeedbackModeWithEthernet[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:MODE
value: enums.FeedbackModeWithEthernet = driver.source.bb.nr5G.hfb.get_mode()

Enables real-time feedback and determines the mode of the feedback line.

return:

fb_mode: OFF| SERial| S3X8 ETH Ethernet feedback mode. OFF Feedback is off. SERial Serial feedback mode. S3X8 Serial 3x8 feedback mode.

get_pdelay() → float[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:PDELay
value: float = driver.source.bb.nr5G.hfb.get_pdelay()

Sets a delay to the slot to which the timing adjustment command (TA) is applied. For example, if ‘Processing Delay’ is set to -2.00 and the TA is received in slot number 6, after processing, the TA is transmitted in slot number 8. If ‘TA State’ > ‘Off’, the value set for ‘Feedback Delay’ is used for ‘Processing Delay’.

return:

processing_delay: float Range: -20 to -1

get_symbol_rate() → FeedbackRateAll[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:SRATe
value: enums.FeedbackRateAll = driver.source.bb.nr5G.hfb.get_symbol_rate()

Sets the bit rate of the serial transmission. For test cases with high subcarrier spacing (SCS) and short slot duration, a serial rate of 115.2 kbps is insufficient. We recommend that you use higher serial rate so that at least one feedback command per slot is received.

return:

fb_serial_rate: No help available

get_ta_mode() → bool[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:TAMode
value: bool = driver.source.bb.nr5G.hfb.get_ta_mode()

Enables timing advance (TA) adjustment for the selected feedback mode. The TA adjustment uses the ‘Processing Delay’ to define a new timing advance value for advancing or delaying the UL transmission.

return:

ta_mode: 1| ON| 0| OFF

set_connector(fb_connector: FeedbackConnectorAll) → None[source]

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:CONNector
driver.source.bb.nr5G.hfb.set_connector(fb_connector = enums.FeedbackConnectorAll.LOCal)

Sets the feedback line connector.

param fb_connector:

# SCPI: [SOURce<HW>]:BB:NR5G:HFB:HPNMode
driver.source.bb.nr5G.hfb.set_hpn_mode(hpn_mode = False)

Enables or disables the HARQ process number (HPN) mode. When the ‘HPN Mode’ is set to active, the additional user delay is set to -1.00 Slots and made unchangeable. An additional ‘HARQ Process Number’parameter is accessible in the PUSCH settings (‘PDSCH and PUSCH scheduling commands’) .

R115 | R1M6 | R1M9 115.2 kbps, 1.6 Mbps, 1.92 Mbps CUST Custom serial rate. You can define the serial rate with [:SOURcehw]:BB:NR5G:HFB:CSRate.
