Impulse response

Hallo,
I am interested in characterizing an ultrasound receiver. I would like to measure its end-of-cable frequency response. The receiver has a central frequency around 0.5 MHz with a bandwidth of possibly 80% or higher.

Is there some ultrasound source with broadband pulses that can be used for this? Does anyone know of any other way to generate an acoustic impulse?

Thanks,
Srirang

Re: Impulse response
Sorry I should have mentioned that the receiver is a hydrophone; the acoustic source needs to be water-immersible.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
