I/Q Gain/Offset/Quadrature Calibration (ESG-D only)
Description
This test determines the required I/Q gain, offset, and quadrature calibration
constants/arrays that will minimize the I/Q modulation imperfections on the output board.
Several calibration constants are determined and then the I/Q gain, offset, and quadrature
DACs are adjusted over frequency to minimize the static vector modulation errors. The
results are stored in the signal generator as calibration arrays.
Required Test Equipment
• None
Procedure
1. Preset the signal generator.
2. Follow the instructions as they appear on the controller’s display.
