im trying to get a signal from a 3 phase voltage measure component from simscape library and want to use the signal with a 2FSK baseband demodulation block?

Hi im currently trying to use a 3 phase voltage measure block from the simscape power library to get a signal which i then want to demodulate with a 2fsk demodulation block from the communication toolbox. i have gotten the signal from the voltage measure block using the goto and from blocks. i get this error when i try to simulate "Complex signal mismatch. Input port 1 of 'plc_FM/M-FSK Demodulator Baseband' expects a signal of numeric type complex. However, it is driven by a signal of numeric type real".
