Notes/Equations

Used in AC simulation
The improvement of system noise figure is given when each element is made noiseless. This is the noise figure (in dB) from the source port to a specified output port, obtained while setting each component noiseless, one at a time. The noise analysis and noise contribution control parameters in the AC Simulation component must be selected. For noise contribution, the output network node must be labeled and referenced on the noise page in the AC Controller. Noise contributors mode should be set to "Sort by Name." The option "Include port noise "on the AC Controller should be selected. For the source, the parameter "Noise" should be set to yes. For this particular budget measurement the AC controller parameter "OutputBudgetIV" can be set to no. The noise figure is always calculated per IEEE standard definition with the input termination at 290 K.

Note Remember that the budget function can refer only to the default dataset, that is, the dataset selected in the data display window.

Budget Path Measurements

This function does not support the budget path feature.
