Berkeley - Model 855B -300 kHz up to 40 GHzMulti-Channel RF / Microwave Signal Generator
The Model 855 Series is a phase coherent multi-output fast switching and low phase noise signal generator with a frequency range from 300 kHz (B only) to 6.2, 12.5, 20.0 or 40 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 10MHz, 100MHz, or 1000 MHz references.
The Model 855 series comes in standard 19 inch 1U (up to 4 channels) or 3U (up to 8 channels) enclosures and offers various control interfaces such as USB, LAN, or GPIB. Each interface allows easy and fast communication using the SCPI 1999 command set. Remote control of the instrument can be quickly attained from any host computer using a free and intuitive GUI. In addition, a customer-supplied application programming interface (API) or programming examples for Matlab, Labview, C++, and other commercially available tools make implementation very straightforward.
The Model 855 offers a handy Phase-Coherent Switching option. While you can set the phase relationship between channels (in degrees) on the standard unit, the Phase-Coherent Switching option allows users to maintain the phase relationship between chanels even while switching frequency.
