Description
Specifies the downconverter module attenuation setting in dB.
Calculate the attenuation setting using desired NIRFSA_ATTR_REFERENCE_LEVEL and NIRFSA_ATTR_MIXER_LEVEL settings, according to the following formula:
attenuation = reference level – mixer level
For example, when using a reference level of 0 dBm (default) with moderate distortion and low noise, specify an attenuation value of 20 dB, as shown by the following calculation:
attenuation = (0 dB reference level) – (–20 dB mixer level
