Interference Rejection
Use this setting when you suspect that other signals in the area are interfering
with a measurement. Interference may look like a spike or lack of stability in the
measurement trace. While monitoring a measurement at a specific frequency,
toggle this setting between ON and OFF. If the measurement result decreases
while ON, then there is an interfering signal in the area. Continue to make
measurements with Interference Rejection ON. However, this will slow the
measurement speed.
Once enabled, up to SIX sweeps may be required before the interfering signal
is neutralized.
This setting can be changed at any time without affecting calibration accuracy.
