U3025AE10 Operational Check
Figure 54 Reflection Tracking Trace (Port 1-2)
10.Compare the Reflection Tracking (1,1) trace to the appropriate limits in Table 12 on
page 43. This can be done using Limit Lines (press Marker/Analysis > Analysis > Limit
Test). The trace should be above the limit. PASS will be displayed on the screen if the
limit lines are used.
11.Repeat step 9 and step 10 for Cal Sets “999.1” thru “999.12” (12-Port).
NOTE For Ports 3-12 the response from 10 MHz to 500 MHz is normal due to the
PNA-X Couplers in comparison to the U3022AE10 bridges. The bridges have
more gain in the coupled RF path.
