New System Simulation Software from ACS
 Escondido, CA, January
28, 2010 -- The
LINC2 VSA (Visual System Architect) software from ACS offers a large variety of new design and analysis
capabilities for designing at the system level. The program renders obsolete many of the traditional spreadsheet
and system cascade calculators once used to analyze system performance. The Visual System Architect combines the
flexibility and ease of use of schematic-based system simulation with a variety of analysis methods. In addition
to cumulative cascade budget plots of gain, NF, IP3, efficiency, signal and DC power, there is a Spectrum Analyzer
type display that plots all the signals and spurs present at any node in the system.
Complete spectral domain analysis is aided by a unique signal and spur viewer that displays every signal
along with its path through the system. The VSA Signal Tree makes it easy to trace the history of any signal or
spur back through the system to its origin. All transformations to the signal are reported, including frequency
translation, amplitude changes and how the signal was created (via fundamental, harmonic, or intermodulation and
the harmonic number or intermod order involved).
The Visual System Architect goes beyond the traditional system
budget plots to offer a much wider array of performance measurement methods and analysis tools. For example, the
program includes a Power Sweep window that graphically displays the linear range as well as the P1dB (1 dB gain
compression) point and compression curve characteristics for the entire system cascade. The Tune menu allows the
user to vary any component parameter to immediately see its effect on system linearity or changes to the
compression point.
The ability to display an input-output power sweep curve extends to any point in the
system, not just to the output port. Thus, the user can probe any node internal to the system and view the linear
range and compression curve characteristics of the system up to and including the selected component.
The
Visual System Architect is a new addition to the LINC2 family of RF and microwave circuit design and simulation
software suites from ACS (Applied Computational Sciences LLC., Escondido, CA). More information about the Visual
System Architect and other LINC2 products from ACS can be found on the ACS web site at
