Measurement
165
10. When using an adapter to the ECal, click Characterization and
then press the softkey corresponding to the characterization for the
adapter you are using.
11. Click Confidence Check.
12. Compare the data trace and the memory trace and verify
whether measurement is correct.
13. The following is the procedure for comparison when
simultaneously displaying the data trace and the memory trace.
a. Press Display key.
b. Click Display > Data & Mem.
c. Press Scale key.
d. Click Auto Scale.
e. Determine whether the difference between the traces is
acceptable. The difference should be read in terms of linear
values instead of dB error. If we consider the magnitude of the
linear error as compared to the dB delta, the value is very
small. So to evaluate the difference between the traces, a
linear error scale should be used for comparison instead of the
dB error scale.
14. For all of the parameters you want to verify, repeat the
procedure.
