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
±
@100kHz – @1.98MHz
to dBc/Hz.
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.
