[Elecraft] KX3 IQ Outputs - What to expect?

Hi John,

In this situation the amplitude of both the I and Q channels should be the
same and they should always be 90 degrees out of phase.

Subject: [Elecraft] KX3 IQ Outputs - What to expect?

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.

John, kx4o
