RFmxTDSCDMA Configure User Defined Channel (Array) VI

Configures all user-defined channels when the channel configuration mode is set to User Defined.
Use equal-sized arrays for Slot Index, Channel Type, and Modulation Type. You can configure up to two channels for the same index for multi-code transmission.

Inputs/Outputs
![]() Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string). Examples: "" "signal::sig1" You can use the RFmxTDSCDMA Build Signal String VI to build the selector string. ![]() Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI. ![]() Slot Index specifies the slot index used for the current user defined channel configuration. The slot index is numbered according to the start time of the acquisition. For example, slot index 0 is the first slot detected in the acquired signal. Valid Values: 0 to 6 ![]() Channel Type specifies the TD-SCDMA channel type. The default value is Idle.
![]() Slot Format specifies the spreading factor, the number of TFCI code words, the number of transmit power control bits, and the number of synchronization shift bits. Refer to the 3GPP TS 25.221 V11.0.0 standard for more information about slot format. The default value is 0. ![]() error in describes error conditions that occur before this node runs. This input provides standard error in functionality. ![]() Modulation Type specifies the modulation type of the corresponding channels. The default value is QPSK.
![]() Channelization Code specifies the channelization code assigned to the channel. The default value is 1. The valid values are 1 to 16. ![]() Instrument Handle Out passes a reference to your RFmx session to the next VI. ![]() error out returns error information. This output provides standard error out functionality. |
