RFmxWLAN OFDMModAcc Fetch Decoded SIG Bits Trace VI

Selector String specifies a selector string comprising of the signal name and result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "" (empty string).

Example:

""

"signal::sig1"

"result::r1"

"signal::sig1/result::r1"

You can use the RFmxWLAN Build Signal String VI to build the selector string.

Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI or the RFmxInstr Initialize NIRFSA (Array) VI.

Timeout specifies the timeout for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the VI waits until the measurement is complete. This value is expressed in seconds. The default value is 10.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

Instrument Handle Out passes a reference of your RFmx session to the next VI.

Decoded SIG Bits returns an array of bits in the HT-SIG field of the 802.11n waveform, the VHT-SIG-A field of the 802.11ac waveform, or the HE-SIG-A field of the 802.11ax waveform.

error out contains error information. This output provides standard error out functionality.
