[Elecraft] KX3 IQ Outputs - What to expect?

[John]

Hello all,

I'm trying to debug something here and need help with some concepts.

Has anyone ever looked at the I and Q outputs of a KX3 with a 2 channel 
o-scope while tuning above and below a fixed carrier - from a test 
source perhaps?

If so can you comment on the relative amplitudes and phase difference 
observed vs. the tuning offset from the test signal?

Thanks.
