Reflection Tracking (E
RF
and E
RR
)
Description Reflection tracking is the difference between the frequency response of the
reference path (R path) and the frequency response of the reflection test path (A or B input
path).
Significant System Components
• open calibration kit device
• short calibration kit device
• R signal path if large variation in both E
RF
and E
RR
• A or B input paths if only one term is affected
Affected Measurements All reflection measurements (high or low return loss) are
affected by the reflection tracking errors.
