Spectrum Analyzers

The SA-MOD-1 spectrum analyzer is based on Avcom’s software-defined-radio technology platform designed to exceed today’s performance challenges. The analyzer is intended for embedded applications required to operate under challenging conditions. Avcom’s newest analyzer technology provides excellent performance by employing high-performance DSP, and FPGAs. Integrators can now embed a full-function spectrum analyzer in a very small volume into systems operating in austere and rugged environments. Communication with the module is achieved via ethernet and Avcom’s Graphical User Interface; the EVO GUI software. It provides a feature-rich set of functions to control, monitor & alarm, while recording. The system can also be accessed via a POSIX-Compliant API, available from Avcom.

The SBS2 Single Board analyzer is the second generation of embedded product designed from the ground up with the system integrator in mind. The compact design measures 3.75”x 5.75” (9.525 x 14.605cm) so that it can easily be integrated into another piece of equipment, inside a small satellite terminal, or as an integral part of the satellite antenna itself.

Performance & Specifications

The SBS2-2150E input covers an extended L-Band frequency of 950MHz to 2150MHz and will also allow monitoring of a 10MHz reference signal. The single board design only requires an external input voltage, accepting a wide range of +15 to +24VDC @ 7W. Communication is provided via Ethernet or USB. The single board supports both commercial Ethernet and USB connectors or header connectors for easier embedded system integration. Along with resolution bandwidths of 1MHz to 10 kHz, a 3kHz RBW option is available for applications requiring very detailed signal analysis. SBS2-2150E allows changes to the number of data points used if application needs to optimize refresh rate verses resolution. The data point number can be adjusted from 1-4000 points in the control software.
