AT690-USB Programmable Attenuator Features

    The AT490 is a universal digital attenuator with standalone supply and small dimensions, providing easy handling and remote control through RS232 9 pins interface.
      Its small size and ease of use will soon make it a must in any RF professionnal or amateur lab.
        Its communication possibilities allows to include it in a larger automated test bench or in complete instrumentation systems.
          The AT690-USB is the extended frequency range version, with some great additionnal features, like USB connection, Li-Ion battery, rugged aluminium housing and graphical display.
            AT490 is also available with 75 Ohms impedance, but with limited frequency range (2.2 GHz) and BNC connectors, as reference AT290-75.
