A novice asks for advice on active ultrasonic probes [Copy link]

I would like to ask you guys, what are the advantages and disadvantages of active ultrasonic probes compared to passive ones.

chunyang

Active ones have internal drive circuits. Generally speaking, they are more expensive than passive ones with self-built drive circuits, but their performance and consistency are usually better. Making your own drive is more flexible and you can achieve the balance you want in performance and cost.

Could you be more specific, sir?

Passive is like headphones, you can use it by plugging it in, it is very convenient but the effect is not good. Active is like speakers, it needs a separate power supply, but the sound quality is just right.

You should read the instruction manual of the active ultrasonic probe and then compare it with the passive one to understand it. In fact, what I said before is detailed enough. Whether you can understand it depends on whether you have the relevant basic knowledge.
