Definition of the system temperature |
| | Various sources contribute to the incoming power, a measure of which is the so-called "system temperature". |
| |  |
| | where the different noise contributions originate from: |

= 3 K microwave and galactic background
= Atmospheric emission
= Ground radiation scattering into the feed
= Losses in the feed and input waveguide
= Injected calibration signal
= Thermal receiver/electronics noise
