Crosstalk measurements in REW

[popeman]

This has probably been already discussed but is there any way of measure crosstalk with REW?

I can't find any info.

Use RightMark Audio Analyzer. Its free and has crosstalk and other features.

Thanks fro the suggestion but RightMark is only on windows, right? Is so, it's not a option for me.

For crosstalk of your soundcard, run loopback cable from output to input. Run sweep with output left channel only, input left channel. Then again with input right channel. Use all SPL trace arithmetic to compare the two.

For crosstalk in electronics best using the RTA stepped sine to make the measurement as the sweep noise floor will be a limiting factor.

Thank you John, I'll read the article once I get a chance.

So, from what I understand there's not direct option for a crosstalk measurements, correct?

I'm considering the pro upgrade some time in the future, mainly to support you effort for this amazing piece of equipment.

There isn't a one-step process to get a result that shows the crosstalk level relative to the drive level. If you run a stepped sine distortion measurement driving one channel and measuring the other you'll get the absolute level of crosstalk vs frequency. With the pro upgrade you could run a stepped sine distortion measurement capturing both channels while only driving one to get distortion behaviour for the driven channel and crosstalk level for the other, but you can get the same data with two measurements without the upgrade.
