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
±
@1.98MHz – @44MHz
to dBc/Hz.
Examines the difference between the
power in the @1.23MHz band and the
noise power in the 30kHz band after IS-98
specified CDMA data is input.
Examines the difference between the
power in the @1.23MHz band and the
noise power at
±
1.98MHz in the 30kHz
band after IS-98 specified CDMA data is
input.
Examines the I and Q gain and phase
error. Examines the USB suppression ratio
after I and Q single-tone F/S data is input.
Examines the change in IF amplitude
between @1kHz – @630kHz.
Examines the on-off settling time of the TX
block when PAON=Low in the TALK mode.

Output when full scale data is input to the
DAC at minimum AGC gain.
Output when full scale data is input to the
DAC at maximum AGC gain.
Examines the input voltage responding to
the control input when 15k
resistance is
series-connected to TAGC_CONT.
Examines the gain difference between
control voltages 1.0 V and 2.0V to examine
the linear control band.
Examines if the gain change between
control voltages 1V – 2V is not ideal.
Examines the noise density between
±
@100kHz – @44MHz when single-tone
F/S data is input. This characteristic
generally depends on the VCO phase noise
characteristics.
Examines the harmonics at the IF when
single -tone F/S data is input.
