Activating Interference Rejection
Other signals sometimes interfere with insertion loss measurements when
measuring the isolation between antennas. When measuring isolation between
antennas in the presence of known or suspected interference, you can minimize the
effect of the interference by activating Interference Rejection in the test set.
NOTE Use of interference rejection will increase the measurement time. Interference
rejection should be used if a known interfering signal exists or if the insertion loss
