class RefsigCls

Refsig commands group definition. 18 total commands, 2 Subgroups, 4 group commands

get_dmrs() → int

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:DMRS
value: int = driver.source.bb.eutra.uplink.refsig.get_dmrs()

Sets the part of the demodulation reference signal (DMRS) index which is broadcasted and therefore valid for the whole cell. This index applies when multiple shifts within a cell are used and is used by the calculation of the DMRS sequence.

return

drs_dmrs: integer Range: 0 to 11

get_ds_shift() → int

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:DSSHift
value: int = driver.source.bb.eutra.uplink.refsig.get_ds_shift()

Sets the delta sequence shift for PUSCH needed for the calculation of the group hopping pattern.

return

delta_seq_shift: integer Range: 0 to 29

get_grp_hopping() → bool

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:GRPHopping
value: bool = driver.source.bb.eutra.uplink.refsig.get_grp_hopping()

Enables/disables group hopping for the uplink reference signals demodulation reference signal (DMRS) and sounding reference signal (SRS) .

return

group_hopping: 1| ON| 0| OFF

get_seq_hopping() → bool

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:SEQHopping
value: bool = driver.source.bb.eutra.uplink.refsig.get_seq_hopping()

Enables/disables sequence hopping for the uplink reference signals demodulation reference signal (DMRS) and sounding reference signal (SRS) .

return

sequence_hopping: 1| ON| 0| OFF

set_dmrs(drs_dmrs: int) → None

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:DMRS
driver.source.bb.eutra.uplink.refsig.set_dmrs(drs_dmrs = 1)

Sets the part of the demodulation reference signal (DMRS) index which is broadcasted and therefore valid for the whole cell. This index applies when multiple shifts within a cell are used and is used by the calculation of the DMRS sequence.

param drs_dmrs

integer Range: 0 to 11

Sets the delta sequence shift for PUSCH needed for the calculation of the group hopping pattern.

param delta_seq_shift

integer Range: 0 to 29

set_grp_hopping(group_hopping: bool) → None

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:GRPHopping
driver.source.bb.eutra.uplink.refsig.set_grp_hopping(group_hopping = False)

Enables/disables group hopping for the uplink reference signals demodulation reference signal (DMRS) and sounding reference signal (SRS) .

param group_hopping

1| ON| 0| OFF

set_seq_hopping(sequence_hopping: bool) → None

# SCPI: [SOURce<HW>]:BB:EUTRa:UL:REFSig:SEQHopping
driver.source.bb.eutra.uplink.refsig.set_seq_hopping(sequence_hopping = False)

Enables/disables sequence hopping for the uplink reference signals demodulation reference signal (DMRS) and sounding reference signal (SRS) .

param sequence_hopping

1| ON| 0| OFF
