Step 8. Perform Quick Check
Step 8. Perform Quick Check
This Quick Check procedure helps to ensure that the system is properly configured.
Perform this check after the PNA has rebooted as a 4-port PNA (previous step).
NOTE An Operator’s Check, used to confirm that the 4-port system is fully
functional, is contained in the N4419B, N4420B, N4421B Service Guide.
Download the Service Guide at www.na.tm.agilent.com/multiport
All four test ports should be open and in the default port mapping configuration.
1. Preset the PNA.
2. Set the stop frequency on the PNA channel to the maximum frequency of either the
test set or the PNA, which ever is lower. This is probably the default setting.
3. On the PNA, click Trace, then Delete Trace to delete the S11 trace.
4. On the PNA, click Trace, then New Trace, then check S12, S13, and S14. Click OK.
This creates three new traces in the same channel and window. All of the new traces
should appear at the bottom, or below, the window.
5. Connect a Thru cable between logical ports 1-2, then between ports 1-3, then between
ports 1-4. This assumes that you have NOT changed port mapping. Port 3 is the PNA
“physical” port 2. Port 2 and port 4 is on the test set.
Each trace should look similar to the uncorrected trace in the following figure.
