4-Channel Programmable Attenuator, 0-95 dB , from 1 to 8000 MHz

Mini-Circuits’ RC4DAT-8G-95 is a 4-channel programmable attenuator suitable for a wide range of signal level control applications from 1 MHz to 8 GHz. Each independently controlled channel provides 0 to 95 dB attenuation in 0.25 dB steps with more than 100 dB isolation between channels. Its unique design maintains linear attenuation change per dB, even at the highest attenuation settings.
All 4 bi-directional RF channels are housed in a single, compact and rugged package with SMA female connectors on all RF ports, a standard Ethernet port (RJ45) and a USB type Mini-B power and control port.
The attenuator can be controlled via USB or Ethernet (supporting both HTTP and Telnet network protocols). Full software support is provided and can be downloaded from our website any time at http://www.minicircuits.com/softwaredownload/patt.html. The package includes our user-friendly GUI application for Windows® and a full API with programming instructions for Windows® and Linux® environments (both 32-bit and 64-bit systems).
