Figure 6-3 Principle Diagram of Z6 Series and Z8 series’ Probe Board
The function of Z6 series and Z8 series probe board describes as following:

The ultrasound signal is transferred from 64-channel to 128-array by the high-voltage
switch on the probe board.

Probe information could be obtained by probe board via reading probe online signal and
probe ID.
