Mini Circuits’ ZVVA-3000 is a 50 RF variable attenuator which combines the performance benefits of a voltage variable design with the convenience and ease-of-use of a software controlled step attenuator. This model operates from 20 MHz to 3 GHz with fine attenuation steps of 0.1 dB and monotonic attenuation transitions, meaning no uncontrolled ‘glitches’ when transitioning from one attenuation to the next.
The attenuator is housed in a compact and rugged package with SMA female connectors for the bi-directional input and output RF ports, a standard 9 pin D-Sub and a USB type Mini-B for power and control.
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 software 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.
