When you encounter a problem on the M9485A launcher such as the modules cannot be displayed, execute the following steps.
Close the M9485A SFP launcher.
Execute the Connection Expert.
Click "Rescan" button at the top left in the Instrument tab.
Execute the M9485A SFP launcher.
If it is still not resolved, reboot the system (chassis and PC).
If it is still not resolved, reinstall the IO library.
When the operator's check or start up self test is failed, read the dialog message and check the cable connection first. The cable connection includes not only cable itself but also the divider and smp-smp adapter which connects between receiver modules and divider.
The operator's check consists of the following three parts.
Module Check
Digital Connection Check
Analog Connection Check
The following figure shows the flow. When a test is failed, an error message is displayed and store the failed information into the log file.
When you have this error, replace the module into the other slot. If the failed slot is still the same, the chassis is suspicious.
Check the front panel cable connections.
Check the Connection Expert to confirm if the chassis is detected correctly.
When you are using non-keysight chassis and digital connection test failed, check the trigger bus routing of chassis. See FAQ of M9485A in the Keysight web page for non-Keysight chassis setup. The trigger bus routing for the Keysight chassis is defined automatically, however, check the chassis SFP to confirm if the trigger bus routing is correct. Refer to the Trigger Bus Routing below. If it is not correct, see Trouble_on_Launcher.
If multiple failures occur, open the M9485A_SelftestLog.txt under C:\Users\Public\Public Documents\Network Analyzer. Check the failed test number (Rx, Sx or Lx) in the log file. See the following tables to find out the failure point.
Here are notes for troubleshooting.
When both module and analog connection checks are failed at the same time, refer to the module test first and check it. When both Sxx and Lxx are filed at the same time in analog connection check, refer to Lxx first and check it. If it seems good, refer to Sxx result.
When PXI trigger bus connection test is failed, confirm if the Connection Expert detects the chassis by clicking "Rescan" in its Instrument tab, then restart Soft Front Panel (SFP) again. If it is still failed, the chassis may have problem. If you are using non-Keysight chassis, see FAQ of M9485A in the Keysight web page for non-Keysight chassis setup.
When the self test is passed but the absolute measurement is noisy, confirm if the unused output ports on the M9340A are terminated with 50 Ω loads.
If you have some same modules, swapping the modules will help to isolate the module.
