on Feb 11, 2018Hello There,
I have questions about N9030A that inside test station with RF alignment failure. Our test station consist of MXG-A, Power meter, switching control unit & PXA.
The test code execute & running in such a way that --- when there’s N9030A perform self-alignment (RF alignment), station’s path connection as well as MXG-A RF output still remains while waiting for PXA to complete its RF alignment. But we found PXA occurred “RF alignment failure” & caused test looping & will only continue once PXA RF alignment is able to pass.
My question here is: does PXA RF alignment will fail if RF input detect external RF source? Will it cause permanent fatal failure if consistently happen in this way to PXA?
Thank you for help in this.
Best Regards,
Tze Chen
Hello Tze Chen,
Your RF alignment may fail if an external signal is applied to the input of the PXA while running alignments (auto or manual). Most likely this will not cause a permanent failure as long as maximum input level of the PXA is not exceeded. To remove this error, simply re-run the alignment.
The analyzer must be aligned to meet specification. To turn on Auto Align, press System, Alignments, Auto Align, Normal. You can also manually align by pressing System, Alignments, Align Now, All. If you are still having problems, press System, Alignments, Restore Align Defaults, then System, Alignments, Align now, All. You can find this in the X-Series Troubleshooting guide, page 111.
You can also use the following SCPI command to follow the Align Now Key path found in the Help Guide chm file
