I/Q Gain/Offset/Quadrature Calibration

Description

This calibration determines the required I/Q gain, offset, and quadrature calibration constants/arrays that
will minimize the I/Q modulation imperfections on the A13 Output. 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.
