How to find frequency of the signal coming from an inverter output, simulink?

I need to find the frequency of the signal coming out from the inverter at AC+ port line as shown below. There is no direct simulink tool to do this and for some reason, I couldn't attach even a scope at the AC+ terminal?

you attatch the scope to voltage and current measurement outputs. You have a voltage measurement right there that you could attatch a scope to. You can use various signal processing blocks in simulink to analyze the frequency content of the signal. You can use something like a phase locked loop: https://www.mathworks.com/help/physmod/sps/powersys/ref/positivesequenceplldriven.html
or you can use the spectrum analyzer, one ships with simscape electrical if you have a newer version. https://www.mathworks.com/help/dsp/ref/spectrumanalyzer.html
