| RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS | Specifies the array of ohmic losses between the noise source and input port of the analyzer during calibration, as a function of frequency. This value is expressed in dB. This loss is accounted for by the noise figure (NF) measurement when you set the RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS_COMPENSATION_ENABLED attribute to True. You must exclude any loss specified by the RFMXSPECAN_ATTR_NF_Y_FACTOR_NOISE_SOURCE_LOSS attribute. |
| RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS_COMPENSATION_ENABLED | Specifies whether the noise figure (NF) measurement accounts for the ohmic losses between the noise source and input port of the analyzer during the calibration step, excluding any losses which you have specified using the RFMXSPECAN_ATTR_NF_Y_FACTOR_NOISE_SOURCE_LOSS attribute. |
| RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS_FREQUENCY | Specifies an array of frequencies corresponding to the ohmic losses between the source and the input port of the analyzer. This value is expressed in Hz. This attribute is applicable only when you set the RFMXSPECAN_ATTR_NF_Y_FACTOR_MODE attribute to Calibrate and set the RFMXSPECAN_ATTR_NF_MEASUREMENT_METHOD attribute to Y-Factor, or when you set the RFMXSPECAN_ATTR_NF_COLD_SOURCE_MODE attribute to Calibrate and set the NF Meas Method attribute to Cold Source. |
| RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS_TEMPERATURE | Specifies the physical temperature of the ohmic loss elements specified by the RFMXSPECAN_ATTR_NF_CALIBRATION_LOSS attribute. This value is expressed in kelvin. |
