Multi-Output RF / Microwave Signal Generator Up to 20GHz with 8 Independent Channels

The Model 855 series is a phase coherent multi-output fast switching and low phase noise signal generator with a frequency range from 10 MHz to 6.2, 12.5, or 20.0 GHz. The 855 is ideally suited for a variety of applications where good signal quality and a wide, accurate output power range are required. Excellent phase noise is combined with spurious and harmonic rejection. A high-stability OCXO reference provides excellent frequency accuracy and stability. The generator accepts external 10, 100, or 1000 MHz references.

The Model 855 series comes in standard 19 inch 1U (up to 3 channels) or 3U (4 to 8 channels) enclosure and offers various control interfaces like USB, LAN, or GPIB. Each interface allows easy and fast communication using SCPI 1999 command set. Remote control of the instrument can be quickly attained from any host system. A customer-supplied application programming interface (API) or programming examples for Matlab, Labview, C++, and other commercially available tools make implementation very straightforward.
