IF Conversion
To downconvert the CDMA the signal, the 114.3 MHz IF is mixed with
a 110.6136 MHz LO to produce a 3.6864 MHz IF in the IQ Modulator
assembly, see
LO signal is phase locked to a 10 MHz signal from the CDMA Reference
assembly, see
CDMA Signal Analysis
The 3.6864 MHz signal goes to the DSP assembly. The DSP assembly
analyzes the 3.6864 MHz signal to make IQ modulation measurements,
such as rho, timing accuracy, carrier feedthrough, and phase error.
Power Measurements
The DSP assembly also makes average power measurements through a
direct link from the RF Input/Output assembly
