This enables RF system designers to identify and correct poor architecture choices early in the design, before commitments are made to the frequency plan, board area, layout, bill of materials, and performance. With more than pre-defined system measurements, and dozens of power and voltage-based behavioral models, designers do not need to spend time writing homegrown code, when they can use a dedicated, graphical tool designed for the RF system design task.
High-quality designs can be produced quickly, saving prototyping cycles, costly troubleshooting, and project risk. Figure 4. Spectrasys accounts for complex mismatch, bi-directional propagation, nonlinearities, frequency response, leakage terms, continuous spectrums from DC to millimeter waves, and tracks individual signal and noise contributors. These can be inspected interactively in seconds, directly from the graphs. WhatIF helps wireless system architects choose a set of Intermediate Frequencies IFs that maximize system performance with a minimum of filtering and design margin for multi-band RF receivers.
It reduces the frequency planning task from weeks of analysis down to an afternoon using an interactive, graphical approach. It accounts for tuned bandwidths, spurs and intermodulated frequencies. Figure 5. The WhatIF frequency planning tool quickly shows the best choices of IF frequencies for best spur-free performance and with lower system complexity.
Of the capabilities of the W, the basic Spectrasys simulator and WhatIF utility are also available as options to the Keysight Genesys environment. If your communications or defense systems contain both RF and signal processing content, require modulation analysis, such as EVM, BER, spectral regrowth, or phased array beamforming, or you need to connect to test equipment, wireless standards references, or interactive baseband modeling, then W RF System Design Kit within SystemVue is the clear choice.

You can use the test benches to measure the gain, noise figure, IP2, and IP3 of your system in different operating conditions. The test bench generates the required stimuli and evaluates the system response to compute the desired measurement. The test bench blocks are useful to validate the performance of your network in the presence of imperfections that are otherwise difficult to estimate analytically.
By comparing the test bench results with the expected analytical results, you gain confidence in the simulation results, you learn how to use the circuit envelope technique, and you verify that your system is correctly modeled. The test benches can also be directly generated from the RF Budget Analyzer app and support both heterodyne as well as homodyne architectures. Example showing how to use the OIP3 measurement test bench top to validate the nonlinearity of a simple receiver in the presence of noise, and results reported by the spectrum analyzer bottom.
