Verification Results Files
When System Verification is configured as recommended, the process produces five
files - one
text file and four .png files. The text file contains model numbers and serial numbers of the PNA
and 85059A kit, along with tabular lists of all results. The other files are screen captures of the
magnitude and phase traces for each verification device. All file names contain the date and
time of the system verification.
Refer to the example screen captures in Figure 6-5, Figure 6-6, Figure 6-7, and Figure 6-8. The
windows are labeled 1, 2, 3, and 4. Window 1 is S
11
, window 2 is S
21
, window 3 is S
12
, and trace
4 is S
22
. Two traces are shown for each measurement - a black trace and a colored trace. The
black traces represent the factory measured data for the verification devices. The colored traces
represent the actual measured data from the calibrated system.
