Description: Specifies whether the carrier is continuous or includes bursts.

If you set this attribute to NIBTSG_VAL_CARRIER_MODE_BURST, the toolkit generates the burst signal by adding zeros at the end of the packet to create one or more complete slots, depending on the packet type. In this mode, the toolkit also shapes the generated waveform to meet the burst ramp characteristics specified in the Bluetooth Test Purposes (TP) specification 1.2/2.0+EDR/2.1/2.1+EDR/3.0/3.0+HS. If you set this attribute to NIBTSG_VAL_CARRIER_MODE_CONTINUOUS, the toolkit generates a phase continuous Bluetooth signal, which is used as an interference signal. This mode is useful to generate an interference signal with pseudorandom bits and continuous phase. In this mode, the NIBTSG_NUMBER_OF_IDLE_SLOTS attribute is not used, and the number of idle slots is assumed be zero. In this mode, NI recommends you to leave the NIBTSG_NUMBER_OF_UNIQUE_PACKETS, NIBTSG_PAYLOAD_DATA_TYPE, and NIBTSG_DIRTY_TX_ENABLED attributes at their default values. Refer to the Carrier Mode topic for more information about the NIBTSG_CARRIER_MODE attribute.

The default value is NIBTSG_VAL_CARRIER_MODE_BURST.
