Figure 5-17: Spectrum Analyzer Display With Carrier Feedthrough
CFT nulling adjusts the I and Q Offset values in the Collector DSP. The I and Q Offset are RFO
FIPS:
parameters 979 and 980, respectively.
As the temperature of the station changes, the CFT component can change. Even a properly
adjusted (nulled) transmitter must be periodically readjusted to assure that the CFT
component is kept at a minimum level.
CFT nulling can be done manually, semiautomatically, or automatically.
Manual Carrier Feedthrough Nulling
This method of nulling the carrier requires the user to enter different I and Q offset values
through the FIPS interface. This method takes the most effort on the part of the user and
contains the highest potential for error. (See RFO FIPS: parameters 979 and 980).
This method should only be used by development engineering. Semiautomatic or automatic
CFT nulling should be used.
