In this case, the output signal should be twice the amplitude of the input signal. If Ri = 1
kΩ and Rf = 2 kΩ, the gain will be:
Gain = 1 + 2000/1000
In this case, the output signal should be three times the amplitude of the input signal.

OPAmpExamplewithFREQOUT.bs2
OPAmpExamplewithFREQOUT.bs2 can be used to supply a 1 kHz sine wave signal to
the amplifier’s input. Whatever the amplitude of this input is, the gain will try to make
the output 1.5 times greater.
