Acquisition Logic AL81G Digitizer Specifications
The AL81G is popular for high-speed scanning using higher-frequency ultrasonic signals. It is most often used to digitize the signals from a UT340 or other high-frequency pulser-receivers.

It features a single channel digitizing with 8-bit resolution, at up to 1 GHz sampling frequency. This provides about 40 dB of useful dynamic range, and is suitable for digitizing RF signals up to about 200 MHz center frequency.

The AL81G has a single input for either quadrature encoder or step-and direction signals. This feature enables the digitizer to keep up with the motion of high-speed scanning systems.

Application Examples:

  • high resolution automated scanners,
  • high resolution thickness gauging
  • flaw detection in advanced metals, coatings and laminates,
  • ultrasonic microscopes,
  • laboratory scanning systems.
