Figure 23-5  Calibration Annotation
1. In the dual-window  
layout, non-trace-specific 
annotations are moved from 
the left of the traces to the 
bottom of the traces
1. No Cal = No calibration 
applied
2. Rcvr Cal = Only receiver 
calibration applied
3. ~User Cal = Receiver Cal 
+ 
User Cal applied, but User 
Cal is interpolated (the 
calibration frequency points 
do not match up with sweep 
frequency points)
4. User Cal = Receiver cal + 
User Cal applied and User 
Cal is not interpolated (the 
calibration frequency points 
match up with sweep 
frequency points)
