Motherboard driving performance for the PCB demo

The STM3210E-EVAL demonstration board (motherboard) has been programmed to show

the STHV748’s main functions. In particular, the firmware installed into the internal memory

allows the PCB demo to be driven in a way that the STHV748 pulser performs an example

of three work conditions:

●

Pulse wave mode (PW), (see Figure 15)

●

Continuous wave mode (CW), (see Figure 16)

●

Pulse cancellation mode (PC), (see Figure 17)
