Phase Noise 15.1.3.2
Displayed Average Noise Level Change over Temperature 15.1.3.3
* Shown for gain 3, attenuator 0 dB. For auto gain/attenuator settings at cold temperatures, a reference
level of -55 dBm may be required for maximum sensitivity, instead of the usual -50 dBm.
Residual Signals over Temperature 15.1.3.4
Temperature typically has little effect on residual signal levels.
