Hey Joseph,
I understand you are trying to connect the “Simscape Voltage Sensor” to the “Simulink Scope”.
You will require the "PS-Simulink Converter" Block between the Voltage Sensor and the Scope. You can find this block in the in Simscape-->Utilities in the library browser. You can connect the block in the following manner
For more information on the "PS-Simulink Converter", you can visit the documentation page.
