RFmxLTE Configure Component Carrier (VI)

Owning Palette: Configuration

Configures the Component Carrier Bandwidth, Component Carrier Frequency, and Cell ID of the component carrier.

Use "carrier<k>" or "subblock<n>/carrier<k>" as the selector string to configure this VI.

Component Carrier Bandwidth specifies the channel bandwidths of the signal being measured. The default value is 10.0 M.

200.0 k (2e5)

Indicates a channel bandwidth of 200 kHz. This value indicates that the received signal is an NB-IoT stand-alone signal.

1.4 M (1.4e6)

Indicates a channel bandwidth of 1.4 MHz.

3.0 M (3e6)

Indicates a channel bandwidth of 3 MHz.

5.0 M (5e6)

Indicates a channel bandwidth of 5 MHz.

10.0 M (10e6)

Indicates a channel bandwidth of 10 MHz.

15.0 M (15e6)

Indicates a channel bandwidth of 15 MHz.

20.0 M (20e6)

Indicates a channel bandwidth of 20 MHz.

Component Carrier Frequency specifies the offsets of the component carrier from the subblock center frequency that you configure in the Center Freq property. This parameter is applicable only if you set the CC Spacing Type property to User. The default value is 0.

Cell ID specifies the physical layer cell identities. The default value is 0. Valid values are 0 to 503, inclusive.

Selector String specifies a selector string comprising of the signal name, subblock number and carrier number. If you do not specify the signal name, the default signal instance is used. The default value is "subblock0/carrier0".

Example:

"subblock0/carrier0"

"signal::sig1/subblock0/carrier0"

You can use the RFmxLTE Build Carrier String VI to build the selector string.
