TwoTone Test Hacks
Performing Two-Tone Analysis Using Circuit Envelope Simulation. This example takes advantage of the properties of real signals--namely, the sum-product equivalence of sinusoids. To perform the same experiment on a different RF system: Choose f1 and f2, the frequencies of the test tones. Use a Simulink Sine source and an Inport block to model.

Two-tone, third-order intermodulation distortion (IM) expresses the degree of non-linearity of an electronic device that has a definable dynamic range, such as an amplifier or mixer. This characteristic is dependent upon input levels, as well as operating frequencies and terminating impedance.

Linearity VS Non Linearity SSB Dual / Two Tone Test Splatter And Harmonics Are A Bad Thing
The typical test of PIM is a two-tone test in which two large equal-amplitude sinusoids are applied to the device under test (DUT) and the level of the intermodulation signals measured. Except for the DUT generating the distortion being passive, distortion appears as described in Section 4.5. PIM is observed in a wide number of situations.

These signals can be represented by two tone testing which is suitable for showing the non-linear behavior of PA. The effects induced are intermodulation distortion (IMD), which is very dominant in third order. The effects of the IMD is even more significant than harmonic distortions of PA.

Here, Δf is a distance between the two-tone stimulus (representing an in-band blocker) and the received RF channel. Note that unlike IP3 test, here, Δf would be typically larger than the spacing between the two-tones. In this case the HD2 products of the two-tone generator are less meaningful as they do not appear at the receiver output, and only the PN is a limiting factor.

The Two Tone, third-order intermodulation distortion (IM) test measures the degree of nonlinearity of an electronic device with a definable dynamic range, such as an amplifier. Nonlinear RF Amplifiers may spread signals into adjacent channels, and or frequencies, which can cause Cross Modulation.

Two-tone testing is a means of testing electronic components and systems, particularly radio systems, for intermodulation distortion. It consists of simultaneously injecting two sinusoidal signals of different frequencies (tones) into the component or system.

Two tone IMD is measured by applying two spectrally pure sinewaves to the ADC at frequencies f1 and f2, usually relatively close together. The amplitude of each tone is set slightly more than 6 dB below full-scale so that the ADC does not clip when the two tones add in-phase.
