niBT RFSA Read Power Spectrum VI

niBT SA session specifies the niBT SA session refnum. Use this parameter to configure the behavior and operation of the appropriate NI Bluetooth Analysis Toolkit VI that accepts the niBT SA session refnum at its input.

instrument handle identifies the instrument session. The toolkit obtains this parameter from the niRFSA Initialize VI or the niRFSA Initialize With Options VI.

timeout specifies the time allotted for the VI to complete before returning a timeout error. This value is expressed in seconds. A value of –1 specifies that the VI waits until all data is available. A value of 0 specifies that the VI returns the available data immediately. The default value is 10.

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

niBT SA session out returns the niBT SA session refnum. Use this reference as the session input to subsequent VIs.

Note  Close the niBT SA session refnum using the niBT SA Close Session VI before the VI completes execution to avoid possible memory leak issues.

instrument handle out passes a reference from the instrument session to the next VI.

power spectrum returns the real-valued power spectrum.

	f0 returns the start frequency of the spectrum. This value is expressed in Hz.
	df returns the frequency interval between data points in the spectrum. This value is expressed in Hz.
	y returns the averaged power spectrum acquired using NI-RFSA.

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