CDMA Measurements - Screens and Control Fields
Control Fields for CDMA Measurements
Anl Special
Analyzer special modes change how IQ modulated signals are analyzed.
• Normal sets the CDMA generator and CDMA analyzer to create and
analyze signals with standard rotation.
• Inverted sets reverse rotation for I and Q signals; opposite to the
direction specified in the IS-95 standards. In this mode, the CDMA
generator creates reverse-rotation IQ signals and the CDMA
analyzer expects reverse-rotation IQ signals.
