SysCalc is a Microsoft Windows-based program for modeling the noise, gain, intermodulation/spurious performance, and compression point of a system of cascaded components where each component is characterized by known parameters. SysCalc’s powerful features allow you to intelligently balance such parameters as dynamic range, sensitivity, spurious levels and gain distribution. And, with its presentation-quality output you can impressively document your designs. SysCalc uses a tabbed-notebook metaphor (See Layout) to organize components into logically independent System pages. The pages are then linked together to form the complete system. Each System page can be uniquely customized to display only the information and data fields that are important to you. There is no limit to the number of components that can be placed on a page or the number of pages that can be linked in a project. You can also attach one or more of SysCalc’s unique Reports to each system. These Reports allow SysCalc to display tailored results, such as yield analysis or graphical performance, as a function of input power, frequency or system temperature.
XML Data Files
Attach XML Data files to any component. Characterize any parameter versus frequency and/or temperature. Data structure accommodates multiple definitions.
S-Parameter files now attachable to any component.
Spline smoothing on both
New AGC Model
'Sequenced' model allows for staged gain (new)
'Ganged' model allows for simultaneous tracking by multiple controls
New Input parameters
| Input/Output Impedance | Input and output impedance can be defined for each component. | |
| Backoff | the Backoff in dB below OP1dB |
New Output parameters
| Gain+ | the cumulative gain (dB) from the from the beginning of the page through the current component. | |
| NF_eff | the effective noise figure (dB) of the component. | |
| NF+ | the cumulative NF_eff (dB) from the from the beginning of the page through the current component. | |
| No | the output noise power (dBm) of the component. | |
| Vi | the component input voltage (rms). | |
| Vo | the component output voltage (rms). |
Each parameter can be related to other parameters within the same component through mathematical expressions. For instance, Psat can be defined as 3 dB above P1dB.
