Hi, I develop a circuit using Simscape blocks. My input signal is developed by simulink blocks, "random number + Matlab function block". I use the simulink-PS converter to join this signal to my circuit, but i can't. What is the problem? Thanks in advance.

Are you connecting the output of the Simulink->PS converter to a source block?
I recommend looking at demos to understand the difference between a physical signal output by the S->PS block and the physical connection between Simscape components.
For more specific help, add more details or an image of your model.

Hi,
No, the output of the Simulink->PS converter in joined directly to the circuit.
The circuit is a parallel RC. The output of the parallel RC is joined to a Voltage Sensor and this is joined to a PS->Simulink and this to a Scope block.
My input signal is a random pulse signal.
I connect the input signal to the Simulink-Ps converter but i can't join this to the parallel RC circuit (i use a solver configuration block).
My project consist in represent the frequency response of a circuit that is excited by a random pulse signal. (low frequency, 1Hz to 1000Hz). Can i use Simscape? or is better use SimRF blocks?
The model is:

Thanks in advanced.

Simscape should be good for your problem.
The problem is that Simscape does not know if the signal coming from the S-PS is your desired current or voltage.
You need a block to specify that, pick one of those:

For the voltage sensor, it should connect, try to connect it a bit farther from the Capacitor port.
