RFMXWLAN_ATTR_OFDMMODACC_RESULTS_PSDU_CRC_STATUS

Data Type: int32
Access: read only
Functions: RFmxWLAN_GetAttributeI32
Description: Indicates whether the cyclic redundancy check (CRC) of the received decoded PLCP service data unit (PSDU) has passed.

The measurement calculates the CRC over the decoded bits, excluding the last 32 bits of each MAC Protocol Data Unit (MPDU). The measurement first compares this value with the CRC value in the received payload, which is represented by the last 32 bits of the MPDU and then aggregates the values.

You do not need to use a selector string to read this result for default signal and result instance. Refer to the Selector Strings topic for information about the string syntax for named signals and results.

Get Function: RFmxWLAN_OFDMModAccGetResultsPSDUCRCStatus
Values:
RFMXWLAN_VAL_OFDMMODACC_PSDU_CRC_STATUS_FAIL (0) Indicates that the PSDU CRC failed.
RFMXWLAN_VAL_OFDMMODACC_PSDU_CRC_STATUS_PASS (1) Indicates that the PSDU CRC passed.

Access: read only
Functions: RFmxWLAN_GetAttributeF64
Description: Returns the duration of the packet extension field for the 802.11ax and 802.11be signals. This value is expressed in seconds.

This result is applicable only when you set the RFMXWLAN_ATTR_OFDM_HEADER_DECODING_ENABLED attribute to RFMXWLAN_VAL_OFDM_HEADER_DECODING_ENABLED_TRUE.

You do not need to use a selector string to read this result for default signal and result instance. Refer to the Selector Strings topic for information about the string syntax for named signals and results.
