I/Q Modulation

I/Q Modulation
The following factors contribute to the error vector magnitude:
• Differences in amplitude, phase, and delay between the I and Q channels
• DC offsets
The I/Q menu not only enables you to select the I/Q signal source and output, it also provides
adjustments and calibrations to compensate for differences in the I and Q signals.
