If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.
	Relative Integrated Power returns the array of powers in the upper offset segment relative to the value returned by the SEM Results Total Aggregated Pwr property. For the intra-band noncontiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.
	Absolute Peak Power returns the array of peak powers in the upper offset segment. For the intra-band noncontiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.
	Relative Peak Power returns the array of peak power in the upper (positive) offset segment relative to the value returned by the SEM Results Total Aggregated Pwr property. For the intra-band noncontiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.
	Peak Frequency returns the array of frequency at which the peak power occurs in the upper (positive) offset segment. For the intra-band noncontiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.
	error out contains error information. This output provides standard error out functionality.

RFmxLTE SEM Fetch Spectrum

Fetches the spectrum used for the SEM measurement.

RFmxLTE SEM Fetch Spectrum

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

Example:

"signal::sig1"

"result::r1"

"signal::sig1/result::r1"

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

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

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

Spectrum returns the spectrum.

	x0 returns the start frequency of the channel. This value is expressed in Hz.
	dx returns the frequency bin spacing. This value is expressed in Hz.
	y returns the array of averaged power measured at each frequency bin. This value is expressed in dBm.

Composite Mask returns the composite mask trace used for the channel. This value is expressed in dBm.

	x0 returns the start frequency of the channel. This value is expressed in Hz.
	dx returns the frequency bin spacing. This value is expressed in Hz.
	y returns the array of composite mask used for the channel.

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