What is IQ correction?

Math of I/Q Correction

is the baseband frequency of the tone. However, due to the different channel environments and component properties, there is usually DC bias, as well as the offset on the phase and the amplitude, which makes the two signals as following: and.

What is IQ modulation?

What's an IQ Modulator? An IQ modulator is a device that converts baseband information into RF signals. Internally, two double-balanced mixers are combined as shown below. By modulating with both in-phase (I) and quadrature (Q) inputs, any arbitrary output amplitude and phase can be selected.

What is IQ gain?

IQ Gain Imbalance indicates the amount of amplifier gain imbalance between I and Q. For example, a value of -6.02 dB means the Q signal is being amplified twice as much as the I signal. This measurement is expressed in dB and calculated over the data in the Measurement Interval.
