Best method for Voltage Attenuation

Dear Engineers,

 

I am writing here to seek for the professional advice on voltage attenuation. Currently I am required to attenuate the voltage from the Ultrasonic controller to feed into National Instruments PCI-6220. The input signal voltage for this NI DAQ is +/-10V, whereas the controller voltages are varies. But we only required few data to be retrieved from the controller as below:-

 

  1. DC Voltage for 12V
  2. DC Voltage for 24V
  3. Ultrasonic Transducer Vpp 30V to +/- 10V
  4. Optional: Amplify DC voltage from 5V to 10V


For the Ultrasonic specification, kindly refer to the attached picture for the signal tapped directly from the transducer. The frequency is 62.5kHz. All the above data are required for real time monitoring and the acceptable error is less than 3%.

 

 

Please advice which solution is the best for my application.

 

Hope to hearing from you soon…and wish all of you a Merry Christmas...

 

 

 

 

Regards

James
