Data Generation
The Digital Cellsite assembly, see
buffers external data that emulates a CDMA traffic channel and
outputs this data to the CDMA Reference, see
The CDMA Reference assembly converts the data into I and Q drive
signals and sends it back to the Digital Cellsite assembly to be summed
with calibrated noise sources. The signals are then passed to the
IQ Modulator
CDMA Reference
The CDMA Reference supplies all the CDMA clocks for the Receive DSP
and the Digital Cellsite assemblies. The CDMA Reference also provides
reference switching for an external or the internal reference source.
