Specifies an array of the ohmic losses between the noise source and the input port of the DUT, as a function of the frequency. This value is expressed in dB. This loss is accounted for by the NF measurement when you set the RFMXSPECAN_ATTR_NF_DUT_INPUT_LOSS_COMPENSATION_ENABLED attribute to True. You must exclude any loss which is inherent to the noise source and is common between the calibration and measurement steps, and configure the loss using the RFMXSPECAN_ATTR_NF_Y_FACTOR_NOISE_SOURCE_LOSS attribute.

Remarks


Specify the frequencies at which the losses were measured using the RFMXSPECAN_ATTR_NF_DUT_INPUT_LOSS_FREQUENCY attribute.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector String topic for information about the string syntax for named signals.

The default value is an empty array.
