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, AH-2020, AG-2010, and AG-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. For high sensitivity, the AH-2010 is available in two different bandwidths: 25 MHz or 100 MHz. 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. For high sensitivity, the AH-2020 is available in two different bandwidths: 25 MHz or 100 MHz. The user can select the setting either by a switch or a TTL signal. Please refer to the datasheet for more information.

AG-2010 Preamplifier (submersible)

The AG-2010 preamplifier offers a similar mix of performance and features as the AH-2010 preamplifier, except that the gain is designed to compensate for frequency variation observed in the HGL-0200 and HGL-0085 hydrophones between 20 and 40 MHz. The combined solution enables the flattest response with a sensitivity that varies less than +/- 3 dB from 0.25 to 40 MHz, which is desirable for accurate measurement of typical pulsed diagnostic ultrasound systems. Please refer to the datasheet for more information.

AG-2020 Preamplifier (submersible, switchable)

The AG-2020 preamplifier offers a similar mix of performance and features as the AH-2020 preamplifier, except that the gain is designed to compensate for frequency variation observed in the HGL-0200 and HGL-0085 hydrophones between 20 and 40 MHz. The combined solution enables the flattest response with a sensitivity that varies less than +/- 3 dB from 0.25 to 40 MHz, which is desirable for accurate measurement of typical pulsed diagnostic ultrasound systems. The AG-2020 preamplifier has two gain settings, selectable by either 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.
