ultrasonic transmitter and receiver measurement

Hi all;

 

We try to setup a system to measure performance of  different ultrasonic receivers and transmitters . For signal generation we decide to use NI 9262 anolog output card. Also we decided to record ultrasonic transmitter outputs with NI9223 anolog input card. However our ultrasonic transmitters maximum input voltages are change between 20Vrms -50Vrms and capacitance values are change between 1500pf-3000pf at 40kHz roughly.  NI 9262 maximum output is 10V -10mA so we figure out that we need an amplifier. Are we on the right path?  Do you know any proper amplifer that we can use?

Hi izafe,

 

I do agree that you need an amplifier, changing the output card is not an option since there are none made by NI that output the 50 V.

 

As for the amplifier suggestion, that is not my area of expertise, but perhaps looking into how Boost Converters work might prove useful for designing your own solution. 

There are several tutorials on Youtube, like this one: https://www.youtube.com/watch?v=vmNpsofY4-U.

 

Good luck!
