Intermodulation Distortion Analysis

Intermodulation Distortion Analysis

Next
Intermodulation analysis is a type of transient analysis in which two sinusoidal signals are applied to an input source and the resulting intermodulation products at the sum and difference frequencies are computed.

Plots of H1, IM2, and IM3 vs F, and both peak and RMS versions of VIN, VOUT, PIN(Input Power), and POUT(Output Power) are available.

The program will optionally find and mark the 1dBm compression point (P1dBm) and the second and third order intercepts (IP2 and IP3).

The analysis makes extensive use of Periodic Steady State techniques to improve accuracy and speed.
