3.4.2 Output Waveform

Table 3-3, Table 3-4, and Table 3-5 show part of the register configuration for TX7516 in CW-mode, B-mode, and elastography mode. Since the pulser input substations are identical for each TMUX9832, all channels of the first TMUX9832 are turned on for testing, measured at TMUX9832 output, and load resistance is 220Ω|220pF.
