NF

Configures averaging for the noise figure (NF) measurement.

Configures the scattering parameters of the DUT as a function of the frequency, for use in the cold source measurement method.

Configures the characteristics of the microwave termination used as a noise source in the cold source method.

Configures the cold source based noise figure (NF) measurement to perform the calibration step or the measurement step.

Configures the effective noise-bandwidth in which power measurements are performed in the noise figure (NF) measurement.

Configures the duration for which the signals are acquired at each frequency to perform the noise figure (NF) measurement.

Configures the noise figure (NF) measurement to use either the Y-factor or the cold source method.

Configures the Y-Factor based noise figure (NF) measurement to perform the calibration step or the measurement step.

Configures excess noise ratio (ENR) and temperature of the noise source used by the Y-factor method.

Configures the ohmic loss inherent to the noise source used in the Y-Factor method that is common to the calibration and the measurement steps.

Configures the time required for the acquisition to wait till the noise source used in the Y-Factor method settles to hot or cold state when the noise source is powered on or off.

Clear the noise figure calibration data for Cold Source and Y-Factor method. Calibration data associated with the selected VSA is cleared for the Cold Source method while calibration data associated with the noise source name and the VSA is cleared for the Y-Factor method.

Loads the ohmic loss data from an S2P file, as a function of frequency of the loss elements between the noise source and the input port of the analyzer during the calibration step, excluding the loss specified as the noise source loss.

Loads the scattering parameter data from an S2P file and configures them as a function of frequency for use in the cold source measurement method.

Loads the characteristics of the microwave termination from an S1P file, which used as a noise source in the cold source method.

Loads the ohmic Input loss data from an S2P file and configures the loss elements between the noise source and the input port of DUT, excluding the losses that are common to the calibration step and the measurement step.

Loads the ohmic Output loss data from an S2P file and configures the loss elements between the output port of the DUT and the input port of the analyzer.

Loads the gain characteristics of the external preamplifier from an S2P file, as a function of frequency. The gain values are expressed in dB.

Loads the ohmic loss from an S2P file, which is inherent to the noise source used in the Y-Factor method that is common to the calibration and the measurement steps.

Computes and sets an appropriate reference level based on the expected maximum DUT gain, maximum DUT noise figure, and other measurement and analyzer attributes. You must not set RFMXINSTR_ATTR_MIXER_LEVEL, RFMXINSTR_ATTR_MIXER_LEVEL_OFFSET, RFMXINSTR_ATTR_IF_OUTPUT_POWER_LEVEL_OFFSET, and RFMXINSTR_ATTR_IF_FILTER_BANDWIDTH attributes in order to obtain an appropriate recommended reference level.

Indicates whether the calibration data is valid for the configuration specified by the signal name in the Selector string parameter.
