Attributes

Specifies the evolved universal terrestrial radio access (E-UTRA) operating frequency band of a subblock, as defined in section 5.2 of the 3GPP TS 36.521 specification.

Specifies the center frequency of the acquired RF signal for a single carrier.

Specifies the index of the component carrier having its center at the user-configured center frequency. RFmx LTE uses this attribute along with RFMXLTE_ATTR_COMPONENT_CARRIER_SPACING_TYPE attribute to calculate the value of the RFMXLTE_ATTR_COMPONENT_CARRIER_FREQUENCY.

Specifies the spacing between two adjacent component carriers within a subblock. Refer to the Channel Spacing and Carrier Frequency Offset and Reference Frequency topics for more information about component carrier spacing.

Specifies the duplexing technique of the signal being measured.

Specifies the downlink eNodeB (Base station) category. Refer to the 3GPP 36.141 specification for more details.

Specifies the attenuation of a switch or cable connected to the RF IN connector of the signal analyzer. This value is expressed in dB. Refer to the RF Attenuation and Signal Levels topic for your device in the NI RF Vector Signal Analyzers Help for more information about attenuation.

Specifies the link direction of the received signal.

Specifies the number of physical antennas available at the DUT for transmission in a MIMO setup.

Specifies the number of subblocks that are configured in intra-band non-contiguous carrier aggregation.

Specifies the reference level which represents the maximum expected power of the RF input signal. This value is configured in dBm for RF devices and as Vpk-pk for baseband devices.

Specifies the margin RFmx adds to the RFMXLTE_ATTR_REFERENCE_LEVEL attribute. The margin avoids clipping and overflow warnings if the input signal exceeds the configured reference level.

Specifies the time to wait before results are available in the RFmxLTE Attribute. This value is expressed in seconds. Set this value to a time longer than expected for fetching the measurement. A value of -1 specifies that the RFmx Attribute waits until the measurement is complete.

Specifies the instrument port to be configured to acquire a signal. Use RFmxInstr_GetAvailablePorts function to get the valid port names.

Specifies the special subframe configuration index. It defines the length of DwPTS, GP, and UpPTS for TDD transmission as defined in the section 4.2 of 3GPP 36.211 specification.

Specifies the offset of the subblock from the center frequency. This value is expressed in Hz.

Specifies the physical antenna connected to the analyzer.

Specifies the configuration of the LTE frame structure in the time division duplex (TDD) mode. Refer to table 4.2-2 of the 3GPP TS 36.211 specification to configure the LTE frame.
