Users can adjust I Offset and Q offset alternately to optimize LO leakage.
4) Quadrature Angle Adjustment
Offset the phase of the Q signal relative to the phase of the I signal. The baseband
quadrature adjustment key is calibrated in units of degrees. This can optimize the
image leakage.
I/Q Output
This adjustment is only applied to the I and Q signal on the rear panel output.
1) I/Q Output Atten
Set the I and Q signal attenuation on the rear panel output. I and Q signals will be
attenuated at the same time.
Range: 0-20 dB.
2) I/Q Output Gain Balance
Adjust I signal amplitude or Q signal amplitude. Range: 4 dB.
When the setting value is positive, the I signal is attenuated, and when the setting
value is negative, the Q signal is attenuated.
3) I Output Offset
This adjusts the DC offset level of the I+ and I- output signal. I+ and I- cannot be
adjusted independently.
4) Q Output Offset
