Preamplifiers and Other Hydrophone Accessories
Onda offers a broad mix of preamplifiers to support your application. There are 3 models offered: AH-1100, AH-2010, and AH-2020. An in-line attenuator, ATH-2000, is also available to increase signal handling for high intensity applications.
Please visit the table of hydrophones and preamplifiers to compare technical specifications and download datasheets.
AH-1100 Preamplifier
The AH-1100 Preamplifier is based on the established AH-17dB design which has been used in the ultrasound measurement laboratory. This low noise design has even flatter response than its predecessor and high reliability SMA connectors to maintain its place as a universal amplifier for any ultrasound acoustic intensity measurement. Please refer to the datasheet for more information.
AH-2010 Preamplifier (submersible)
The AH-2010 Preamplifier offers a great combination of performance and features. Designed as an electronic and mechanical match for Onda hydrophones, the AH-2010 is well-suited for submersible measurements with only one coaxial cable going to the oscilloscope. It has a superb frequency response, low noise and high stability. Please refer to the datasheet for more information.
AH-2020 Preamplifier (submersible, switchable)
The AH-2020 Preamplifier is the ultimate combination of performance and features. This preamplifier is also designed to be submersible similar to the AH-2010, but it offers a selectable dual-gain setting for > 75 dB dynamic range. At the oscilloscope, the user can select the setting either by a switch or a TTL signal. Please refer to the datasheet for more information.
ATH-2000 Hydrophone Attenuator
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.Please refer to the datasheet for more information.
