Measurements and Testbenches

Analyze performance metrics of analog and mixed-signal systems

Analyze different foundation blocks and system-level models of mixed-signal systems using measurement blocks and testbenches. You can validate a block from the Mixed-Signal Blockset™ library, or you can validate your own customized blocks.

For PLL, use the measurement blocks to analyze performance metrics such as phase noise, reference and fractional spurs, aperture jitter, timing impairments, and lock time. Use block-specific testbenches to validate your customized blocks.

For ADC, use the measurement blocks to analyze key performance metrics such as aperture jitter, SNR, SINAD, noise floor, offset error, and gain error.

Use a system-level testbench to validate your PLL and ADC models.
