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.

# 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

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