Mini-Circuits’ RUDAT-6000-90 is a general purpose, single channel programmable attenuator suitable for a wide range of signal level control applications from 1 MHz to 6 GHz. The Attenuator provides 0 to 90 dB attenuation in 0.25 dB steps. Its unique design maintains linear attenuation change per dB, even at the highest attenuation settings.
The attenuator is housed in a compact and rugged package with SMA female connectors on the bi-directional input and output RF ports, a standard 9 pin D-Sub and a USB type Mini-B power and control ports.
The attenuator can be controlled via USB or RS232 (via D-Sub connector). 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).
