Your source for quality GNSS Networking Solutions and Design Services!Page 2 of 7DescriptionIdeal for Automated Test Environments (ATE), the <strong>AT11DV</strong> is a high dynamic rangedigital attenuator. Designed specifically for GPS applications, the <strong>AT11DV</strong> has provisionsfor supplying the DC voltage for the active antenna, including an optional feature formonitoring the health of the receive antenna system. The product includes additionaloptional features for oscillation detection and prevention, and filtering for the GPS L1 & L2bands. The <strong>AT11DV</strong> features digital display with a user friendly menu enabling easyoperation and configuration of the device. With an optional Bluetooth wireless interfacealso available, the <strong>AT11DV</strong> may be configured remotely when access to the system is notconvenient.Call, email (sales@gpssource.com), or visit our website (www.gpssource.com) for furtherinformation on product options, specifications, or to receive an easy to use order sheet.Document no: 433 Rev: 004 9 JUL 08
