Linear control range examination that
measures the gain difference between
control voltages, 1.0V and 2.0V.
Examines how far the gain change
between control voltages 1V – 2V is from
the ideal

when two in-band 0.5F/S signal are input to
the DAC
Spurious measurement between

the IF output when two in-band 0.5F/S
signal are input to the DAC.
Spurious measurement above

Examines the carrier feed through when I
and Q single-tone F/S in-band CDMA
spread spectrum data are input.
Examines the IF harmonics in the 1.23MHz
range after I and Q single tone F/S data
are input.

Sets the control voltage so that AGC IF
outputs -83.2dBm – 0.8dBm when I and Q
single tone F/S data are input. Converts
the noise within
