- Updated2025-10-13
- 3 minute(s) read
Automatically detects the standard, channel bandwidth, and burst length of the input signal, and writes the Detected Standard, Detected Channel Bandwidth, and Detected Burst Length properties.
You must configure the Reference Level property before calling this VI. If the peak power level of the input is unknown, you can call the RFmxWLAN Auto Level VI to configure the Reference Level property after you set the Standard and Channel Bandwidth properties to values corresponding to maximum expected channel bandwidth.

Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string). Example: "" "signal::sig1" 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 (s)
—
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 (no error)
