Analog-digital port B-381 (В-181)


The analog-digital port is a multichannel input / output system of analog and digital signals.

It includes:
  • 4-channel ADP for input in a computer and processing of analog signals;
  • 4-channel DAP for arbitrary shape signals generation ;
  • The 16-channel logic analyzer / generator for digital signals input / output.
Model B-181 is designed as the measuring module which is built in the measuring complex UNIPRO.

Model B-381 is designed as the separate device connected to a computer.
