RF Systems

Comprehensive "RF Systems" Solution

More specifically, Visual System Simulator™ (VSS) software is an RF and wireless communication systems design environment that allows designers of commercial and military transmitters and receivers
 to quickly and easily create subsystem architectures and optimize each of their components for best overall performance.

Seamless integration with Microwave Office® software makes it easy to move from system level design and behavioral modeling to detailed component-level design and ultimately performance evaluation with measurements based on signals provided by physical or virtual instruments. VSS supports all current communication standards, such as LTE, DVB-H/DVB-T, WiMAX/ 802.16d-2004/802.16e-2005 (mobile and fixed), CDMA2000, GSM/EDGE, WLAN/802.11a/b/g, 3G WCDMA FDD, and IS95.


Visual System Simulator for Radar Systems

VSS for Radar Systems allows detailed behavioral modeling of the RF and signal processing of a radar system, together with 3D antenna patterns derived from synthesis or measurement. Links to MATLAB and LabVIEW provide for custom signal processing algorthms. Links to instruments like NI’s PXI, R&S’s and Anritsu’s VSG/ VNAs allow a real DUT to be incorporated into the simulation, capture real world signals, or synthesize an impaired signal from a point in the simulated system.

VSS for Radar Systems can be classified as ground-based, airborne, space borne or ship-based. They can also be classified by frequency band, antenna or waveform type. Functionality varies from tracking to early warning, and to over the horizon and more.

Visual System Simulator for LTE Communication Systems

Long Term Evolution (LTE) is rapidly being deployed by major U.S. carriers and will serve most, if not all, top-tier markets by the end of 2012. The challenges for designers in producing the best performance in systems destined for LTE service are similar to those for other standards such as Worldwide Interoperability for Microwave Access (WiMAX) and include high peak-to-average ratios (PARs) and tight requirements for adjacent channel leakage ratio (ACLR) and error vector magnitude (EVM).

VSS for LTE Communication Systems includes all requirements for Layer 1 (physical layer) outlined in the LTE standard from the 3rd Generation Partnership Project (3GPP). It enables RF/analog engineers, with minimal effort, to evaluate LTE communication systems inclusive of the analog impairments due to the RF chain. Having such capabilities helps designers to reduce time-to-market by eliminating iterations and rework, and cuts system costs by ensuring that components are not over-specified and needlessly expensive.
