How to generate a variable frequency AC voltage source on simulink?

I want to simulate an RLC circuit that measures voltage at the output as a function of frequency for a variable frequency changing sinusoidal input voltage.

I used Simulink to create the circuit and it works well for individual values of f.

I want to change the frequency of the input signal over time during a single simulation

But when I try to put a range of values for the frequency, I get the error message:

'Invalid parameter in block '. The 'Frequency' parameter must be a scalar value.

How to solve the problem please?

Hi @Rosine DJUIDJE,

I understand that you want to change the frequency of the input signal over time during a single simulation.

Please follow the link below for an answer to a similar question. Do go through the comments and the provided link in the comments if necessary.

Hello,@Dhaniklal

Thank you so much for your response.

Indeed, I want to make this type of circuit as shown in the attached image. I dont use simscape, i use simulink.

I don't know how to vary the frequency in this AC voltage source.

please give me some suggestions,
