U3042AE12 Troubleshooting Operational Check Failures
Troubleshooting Operational Check Failures 
If your test results fail the Operational Check limits, verify following:
1. Insure that the test set is turned on and connected properly to the PNA.
2. Check all appropriate network analyzer and test set connectors for damage, cleanliness, 
and proper torque.
3. Repeat the relevant 1-Port calibrations.
4. Verify that the stand-alone network analyzer is operating properly and meeting its 
published specifications. 
Interconnect Cable Verification
1. Connect the Test Set to the PNA and select Multiport mode.
2. Verify the Source Interconnect RF cables (Source Out and CPLR THRU).
a. Remove the Receiver and CPLR ARM interconnect cables and install the standard 
PNA jumpers.
b. Connect two RF cables on the PNA, Port-1 to Port-2 and Port-3 to Port-4.
c. Set the PNA to measure Trace S12, S21, S34 and S43, and verify that there are no 
power holes. If S12, or S34 has a power hole check the Port-2, or Port-4 Source 
interconnect cables and test set connectors for damage. If S21, or S43 has a power 
hole check the Port-1, or Port-3 Source interconnect cables and test set connectors for 
damage. 
3. Verify the Receiver Interconnect RF cables (Receiver A IN or B IN and CPLR ARM).
a. Re-install the Receiver and CPLR ARM interconnect cables.
b. Remove the Source Out and CPLR THRU interconnect cables and install the 
standard PNA jumpers.
c. Set the PNA to measure Trace S12, S21, S34 and S43. Verify that there are no power 
holes. If S12 or S34 has a power hole check Port-1, or Port-3 Receiver Interconnect 
cables and test set connectors for damage. If S21, or S43 has a power hole check 
Port-2, or Port-4 Receiver Interconnect cables and test set connectors for damage. 
4. If the problem still exists, connect the standard jumpers to the PNA (Source and 
Receiver) and verify the Source Out to CPLR THRU and A/B IN to CPLR ARM switch 
paths. 
a. Connect two RF cable, one to Port-1 and one to Port-2.
b. Set the PNA to measure trace S12 (all standard jumpers connected).
c. Connect the Port-1 cable to Source Out and Port-2 cable to CPLR THRU connectors 
on the test set. If a power hole still exists refer to “Contacting Agilent” on page 94.
d. Connect Port-1 to Receiver A IN or B IN and Port-2 to CPLR ARM connectors on the 
test set. If a power hole still exists refer to “Contacting Agilent”.
