①Dynamic range is measured with maximum pulse width, averaging time is 3 minutes, SNR=1; The level difference between the RMS noise level and the level where near end back-scattering occurs.


②Event dead zone is measured with the pulse width of 3ns; attenuation dead zone is measured with the pulse width of 5ns.
