niRFSG 5611 Configure RF Gain Calibration VI

instrument handle identifies your instrument calibration session. instrument handle is obtained from the niRFSG Initialize External Calibration VI.

instrument transition power specifies the approximate bottom of the power meter's range where it becomes either too slow or too inaccurate.

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 instrument session to the next VI.

spectrum analyzer reference level returns the value at which to set the spectrum analyzer reference level.

measurement instrument specifies the instrument(s) to use for measuring the output power.

frequency to measure indicates the frequency of the generated signal. This value is expressed in hertz. The power of the generated signal should be measured.

external LO settings indicates the options to set if an LO source is used instead of the PXI/PXIe-5652.

	LO In Frequency indicates the tone frequency to generate with the LO source.
	LO In Power indicates the output power to generate with the LO source.

external AWG settings indicates the options to set if an arbitrary waveform generator (AWG) is used instead of the PXIe-5450.

	Offset Frequency indicates the tone frequency to generate with the AWG.
	Power indicates the output power to generate with the AWG.
	Impairments indicates the properties to apply to the I/Q signal to achieve desirable calibration results. I Offset specifies the DC offset to generate on the I signal. Q Offset specifies the DC offset to generate on the Q signal. Qtr Skew specifies the adjustment of the phase angle between the I and Q vectors. If the skew is zero, the phase angle is 90 degrees. Gain Imb specifies the power ratio (I power / Q power) to generate.

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