Dual-Channel Crosstalk

A crosstalk measurement analyzes the amplification and phase lag between the reference channel and the idle response channel at the test frequency.

You can identify the detected tone amplitude and phase on the stimulus channel. The stimulus tone amplitude and phase are treated as references when specifying the tone relative amplitude and phase of the idle response channel. You can search for an idle response tone at the same frequency as the stimulus tone.

The measurement analysis of crosstalk is equivalent to that performed for a gain and phase measurement. The difference between these two measurements is that the gain and phase measurement is applied on the active response channel, while the crosstalk measurement is applied to the idle response channel. The following figure shows this difference.
