Figure 1. Transient Analysis window.
Consider the RF Amplifier circuit shown in Figure 2. The amplifier is configured for maximum output power at 1.5MHz. In this example you will add a custom expression to a Transient Analysis to multiply the input by the output voltages.

Figure 3. Analysis parameters for the Transient Analysis.
Refer to the Transient Analysis tutorial for more details on how to configure the Analysis Parameters tab.
You can now add an expression to analysis. The items in the Variables in circuit list display the voltage and current values which can be grouped into expressions. The output voltage is represented by the variable V(Output) and the voltage taken at the input is represented by the variable V(Input).
