3.4.3 Thermal Test

During testing, the pulse output was connected to the real PZT probe. Next, the temperature rise of the TMUX9832 and TX7516 were tested after 10 minutes of continuous shear wave output. The TMUX9832 device was at the following conditions:

  • Only 16 channels were open
  • Elastography pulse repetition frequency (PRF) = 20Hz
  • Frequency = 2.5MHz
  • Transition pulser counts = 1250
  • 70V peak voltage
