The scope is fine. The - terminla of the function generator shouldn't be connected to anything.bos1234 said:

You've currently got the scope negative connected to the opamp negative input, which should be a "virtual earth" (if your circuit was working properly). Whether or not it will make a difference in multisim, in real life you shouldn't be adding extra capacitance and perhaps extra noise pickup here. You should connect it directly to a zero volt point (earth) instead.bos1234 said:
A summer inverter op amp is a type of operational amplifier circuit that combines multiple input signals and produces an inverted output signal. It works by using an inverting amplifier configuration, where the output voltage is the inverse of the input voltage. The inputs are summed together and fed into the inverting input of the op amp, which amplifies and inverts the signal to produce the output.
A summer inverter op amp circuit typically consists of an op amp, resistors, and input signals. The op amp is usually a single integrated circuit, while the resistors are used to set the amplification and inversion levels. The input signals can be from various sources, such as sensors or other electronic circuits.
One of the main advantages of a summer inverter op amp circuit is its ability to combine and invert multiple input signals with high precision. It also has a high input impedance, which means it does not draw much current from the input signals, making it suitable for use with low current sources. Additionally, op amps are widely available and relatively inexpensive, making them a cost-effective choice for electronic circuits.
To simulate a summer inverter op amp circuit using Multisim, you can use the "Operational Amplifiers" category in the component library to select an op amp and place it on the circuit diagram. Then, you can add resistors and connect them to the appropriate pins of the op amp. Finally, you can add the input signals and connect them to the resistors. You can then run the simulation and observe the output signal.
Summer inverter op amp circuits are commonly used in electronic circuits for signal processing and conditioning. They can be used in audio amplifiers, filters, and oscillators, among other applications. They are also used in electronic instruments, such as oscilloscopes and function generators, to amplify and invert input signals for display and analysis.
