Vertical:Mixer Level (dBm)
Short Name: Mixer Level
Specifies the mixer level. The value is expressed in dBm. The mixer level represents the attenuation to apply to the input RF signal as it reaches the first mixer in the signal chain. NI-RFSA automatically selects an optimal mixer level value given the reference level if you do not configure this property. Reference level, attenuation, and mixer level are related by the following relationship:
attenuation = reference level – mixer level
mixer level < reference level
reference level – mixer level <= 50 dB
The following table shows the relationship between mixer level and noise and distortion.
| Mixer Level | Noise and Distortion Effects |
|---|---|
| –20 dB | Moderate distortion, low noise |
| –30 dB | Best compromise between distortion and noise |
| –40 dB | Low distortion, high noise |
