Attributes

Specifies whether the cell ID of component carrier is auto calculated and configured by the measurement or configured by the user.

Specifies the evolved universal terrestrial radio access (E-UTRA) or NR operating frequency band of a subblock as specified in section 5.2 of the 3GPP 38.101-1/2/3 specification. Band determines the spectral flatness mask and spectral emission mask.

Specifies the center frequency of the acquired RF signal. This value is expressed in Hz. The signal analyzer tunes to this frequency.

Specifies the subblock channel raster which is used for computing nominal spacing between aggregated carriers as specified in section 5.4A.1 of 3GPP 38.101-1/2 specification and section 5.4.1.2 of 3GPP TS 38.104 specification. The value is expressed in Hz.

Specifies the index of the component carrier having its center at the user-configured center frequency. The measurement uses this attribute along with RFMXNR_ATTR_COMPONENT_CARRIER_SPACING_TYPE attribute to calculate the value of the RFMXNR_ATTR_COMPONENT_CARRIER_FREQUENCY. This attribute is ignored if you set the CC Spacing Type attribute to User.

Specifies the spacing between adjacent component carriers (CCs) within a subblock.

Specifies the downlink channel configuration mode.

Specifies whether the cell ID of downlink test model component carriers is auto calculated and configured by the measurement or configured by the user.

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

Specifies whether to use channel bandwidth and subcarrier spacing configuration supported in Frequency Range 1 (sub 6GHz), Frequency Range 2-1 (between 24.25GHz and 52.6GHz) or Frequency Range 2-2 (between 52.6GHz and 71GHz).

Specifies the downlink gNodeB (Base Station) category. Refer to the 3GPP 38.104 specification for more information about gNodeB category.

Specifies the downlink gNodeB (Base Station) type. Refer to the 3GPP 38.104 specification for more information about gNodeB Type.

Specifies the link direction of the received signal.

Specifies the number of receive chains.

Specifies the number of subblocks configured in intraband non-contiguous carrier aggregation scenarios.

Specifies the frequency used for phase compensation of the signal when you set the RFMXNR_ATTR_PHASE_COMPENSATION attribute to User Defined. This value is expressed in Hz.

Specifies the power boost for PI/2 BPSK signal when you set the RFMXNR_ATTR_FREQUENCY_RANGE attribute to Range 1. This attribute is valid only for uplink direction.

Specifies the power class for the UE as specified in section 6.2 of 3GPP 38.101-1/2/3 specification.

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

Specifies the margin RFmx adds to the RFMXNR_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 RFmxNR Attribute. This value is expressed in seconds.

Specifies the downlink SAN (Satellite Access Node) class representing the satellite constellation as specified in section 6.6.4 of 3GPP 38.108 specification.

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

Specifies the adjustment of the center frequency for adjacent E-UTRA and NR Channels in case of nominal spacing. The value is expressed in Hz.

Specifies the offset of the subblock from the RFMXNR_ATTR_CENTER_FREQUENCY.

Specifies the frequency of the transmitters local oscillator. This value is expressed in Hz. The frequency is defined per subblock and relative to the respective subblock center frequency.

Specifies the physical antenna that is currently connected to the analyzer.
