I/Q Calibration (Option UNG Only)
The intent of performing the I/Q calibration is to reduce or eliminate
the undesired-sideband signal and the carrier feedthrough signal.
Adjustments to the ratio of I Gain to Q Gain as well as adjustments to
Quadrature can minimize the undesired-sideband signal. For example:
1. leave Q Gain fixed and adjust I Gain until the undesired-sideband
signal is minimized
2. adjust Quadrature until the undesired-sideband signal is minimized
3. repeat this process a few times between the I Gain, Q Gain, and
Quadrature adjustments to obtain the best overall reduction in the
level of the undesired-sideband signal
Adjustments to the I Offset and Q Offset can minimize the carrier
feedthrough signal. For example:
1. adjust I Offset until the carrier feedthrough signal is minimized
2. adjust Q Offset until the carrier feedthrough signal is minimized
3. repeat this process a few times between the I Offset and Q Offset
adjustments to obtain the best overall reduction in carrier
feedthrough
