FSA stands for vehicle system analysis. It is measuring equipment for electrical and engine-related signals, rather than solely a serial ECU scan tool. Bosch documents modular systems including FSA 500 and the FSA 7xx family.
The FSA 720 is a PC-connected measurement module; Bosch specifies a two-channel oscilloscope and component tests, with CompacSoft[plus] required for certain guided tests. A KTS interface can be combined for ECU values. FSA 740 and 750 are other system configurations; check their actual supplied instruments and probes.
Follow the limits and measurement category of the specific instrument and probes. Hybrid and high-voltage work requires the correct equipment and training.
