Overview
The CAEN Mod.DT1081B Desktop Four Fold Programmable Logic Unit is a laboratory tool that incorporates in a single handy Desktop module the most common functionalities that you need to implement the logic capabilities of your experiment.
The module is organized in four sections, with 6 inputs and 4 outputs each accepting TTL/NIM signals, with the possibility to feed in analog signals and process them through a leading-edge discriminator. The input stage features an asynchronous Gate&Delay with 5 ns resolution while the output stage feature an asynchronous Monostable stage. This allows the user to trim at best the needed parameters and to perform accurate measurements using the available logic functions.
Each section is configurable independently according to one of the available pre-programmed functions. The board configuration can be performed using the 2.8” touch screen display or via the web-interface, accessible via USB or Ethernet.
On the touch screen interface, each function is associated to a widget, meant to be used for configuration and monitor purposes.
The web-interface allows the user to remotely configure the instrument via USB or Ethernet, monitor the functions output, dump data on file or history chart and access to the most advanced functions. No software installation is required!
