Onda -Model ATH-2000 -Medical Hydrophone Attenuators
FromOnda Corporation
In conjunction with the family of Onda hydrophones, the ATH-2000 increases the preamp large signal handling by 20 dB to accommodate high intensity applications such as HITU. Its in-line "cable-free" configuration allows fully submersible measurements while eliminating the risk of cable resonance and scope impedance mismatches. The ATH-2000 is compatible with all AH-20x0 and AG-20x0 series preamplifiers as well as HN and HGL hydrophones.
