Four ways it responds
Each card is a real question to the running system and the start of its answer. The badges are the ones the technician sees. In use, the tech names the manufacturer and platform, and the copilot answers only from that system’s documentation. Names are left out here.
Grounded in the OEM manual
troubleshooting
A DAS remote shows a VSWR alarm. How do I troubleshoot it?
Check the RF path components
- Inspect the coax path for visible damage or stress.
- Verify every connector along the path is mated and clean.
- Check that the antenna connections are secure.
Check the system status
- Open Command & Control, select the BIU, then review History > Event Log.
Fully groundedOEM 3General DAS 2
Why it reads this way: fault questions about a named platform keep two evidence slots for general fault isolation, so the physical checks come first and the vendor menus second.
General checks, clearly labeled
no platform procedures on file
The optical link to remote 3 shows low optical power. What do I check?
These are general DAS checks, not this platform’s procedures. Confirm alarm meanings, thresholds, and the approved procedure in the manufacturer’s documentation before acting.
- Inspect the connection, clean it, then inspect it again.
- Verify the wavelength, fiber, polish, and polarity.
- Measure both endpoint powers.
- Run OLTS or OTDR as appropriate.
- Compare the results with the engineered budget.
Partially groundedGeneral DAS 5
Why it reads this way: a tech asking what to check gets the method. Asking what the alarm means on this platform is still refused, because that answer has to come from the manufacturer.
No pass/fail without criteria
measurement
Is 14 dB return loss a pass?
I can explain what 14 dB means, but I cannot call it pass or fail without the applicable project, carrier, OEM, regulatory, standard, or AHJ acceptance criteria.
Next checks
- Find the approved acceptance criteria for the site, band, and measurement location before recording a result.
Partially groundedGeneral DAS 5
Why it reads this way: the same number can pass on one project and fail on another. The verdict belongs to the acceptance document, not the model.
Declines rather than guess
specification
What torque should I use on a 4.3-10 connector?
No verified guidance covers this, so no answer is given rather than a guess. Check the OEM documentation or the project acceptance criteria for this site.
Insufficient evidenceGeneral DAS 5
Why it reads this way: none of the sources states a torque value. A plausible number from the model's memory would read as fact on site.
