get(channelNull=ChannelNull.Default) → RsSmbv.enums.ChanCodType

# SCPI: [SOURce<HW>]:BB:W3GPp:BSTation:ENHanced:CHANnel<CH0>:DPCH:CCODing:TYPE
value: enums.ChanCodType = driver.source.bb.w3Gpp.bstation.enhanced.channel.dpch.ccoding.typePy.get(channelNull = repcap.ChannelNull.Default)

The command selects the channel coding scheme in accordance with the 3GPP specification. The 3GPP specification defines 4 reference measurement channel coding types, which differ in the input data bit rate to be processed (12.2, 64, 144 and 384 ksps) . The additional AMR CODER coding scheme generates the coding of a voice channel. The BTFD coding types with different data rates are also defined in the 3GPP specification (TS 34.121) . They are used for the receiver quality test Blind Transport Format Detection. When a channel coding type conforms to the standard and channel coding is activated, (BB:W3GP:BST:ENH:CHAN<n>:DPCH:CCOD:STAT) the slot format (BB:W3GP:BST:ENH:CHAN<n>:DPCH:CCOD:SFOR) and thus the symbol rate (BB:W3GP:BST:ENH:CHAN<n>:DPCH:CCOD:SRAT) , the bits per frame, (BB:W3GP:BST:ENH:CHAN<n>:DPCH:CCOD:BPFR) , the pilot length (BB:W3GP:BST1:CHAN<n>:DPCC:PLEN) and the TFCI state (BB:W3GP:BST1:CHAN<n>:DPCC:TFCI:STAT) are set to the associated values.

param channelNull

optional repeated capability selector. Default value: Nr0 (settable in the interface ‘Channel’)
