仿真GPS接收机中的锁频环功能，与硬件设计十分相似，稍作改动即可实现锁相环功能(Simulation of GPS receiver in frequency-locked loop functions, and hardware design is very similar, minor modifications to achieve phase-locked loop function)

These probes are for use with the Simscape multi-domain physical modeling tools (Simscape, SimHydraulics and SimElectronics). The ssc_Probes.slx library file contains probes for viewing the through and across variable for each domain. The ssc_dc_motor.slx model file is an example of how to use. See Help block for additional usage notes.
