Gen Special Input Atten
Gen Special
Generator special modes change how IQ modulated signals are
generated.
• 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.

CDMA GENERATOR
Input Atten
This field controls the RF attenuators of the Test Set. If an ADC
Overdriven message is displayed at the top of the screen while
making measurements, increase the attenuator setting until the
message is no longer displayed. This is the coarse level adjustment for
the signal level into the CDMA analyzer. Fine level adjustment is
performed using the Gain field.
See the "Gain" field on page 100 for more information.
NOTE The Input Atten setting does not affect, and is not
displayed with, the average power measurement.
