what model of PC Oscilloscopes and probes I can choose?

:?
I want to measure audio frequency and ultrasonic in air and in water(under water), and then analyse the data. So the instrument must fit the following:
1. Frequency range: DC to 5 MHz or 10 MHz;
2. Frequency analyser(FFT Function);
3. Proper probes or sensors by which I can measure audio and ultrasonic frequency in water and under water.

How to choose your products, please give me some advice.

Thanks a lot!

Hello zhouwp,

Please view the application note at this link http://www.picotech.com/applications/oscilloscope_tutorial.html for the basics of choosing an oscilloscope.

All of our oscilloscopes will allow spectral analyses, and for the frequency range that you require, the choice is wide. However, a 12-bit unit will yield the greatest resolution and dynamic range (http://www.picotech.com/oscilloscope-sp ... tions.html).

With regard to sensors, you would need to source those yourself as they are specialised applications. In general though, they should be voltage output with BNC terminations (ideally). A web search should find what you require.
