The UPM functional check runs a prescribed scan in the forward power. It compares the measured RF power from the UPM to the expected value stored in the UPM configuration file.
Procedure
- Make sure the RF enable switch is in the DISABLE (down) position.
- For body channel, disconnect J4 and connect the dummy load to J4.
- Set the RF enable switch to the On position.
- Press Landmark. Then, advance to scan. A phantom is not needed.
- On the Common Service Desktop, from the Calibration menu, select Calibration > Calibration Wizard and select Click here to start this tool.
- On the Common Service Desktop, from the Calibration menu, select Calibration > UPM and Click here to start this tool.
On the Common Service Desktop, from the Calibration menu, select Calibration > RAP and Click here to start this tool.
- In the tool, make the following functional check selections:
(For system running DV26.0 or earlier)
| Setting | Value |
|---|
| Task | UPM Func Chk |
| RF Chain | Body Channel |
Note: The Power Type drop-down menu is inactive for this step.
(For system running DV29.1 or later) | Setting | Value |
|---|
| Task | Power Monitor Functional Check |
| RF Chain | Body |
- Click Start.
- Click Yes when the prompt asks if the hardware setup is correct.
- Review the system prompts as they are shown during test execution.
This functional check takes 2 to 3 minutes before any user interaction is required. Functional check tests include: 10-second average power check, RF inhibit test, and short-term average power fault host trip test.
- Look for a dialog box about the UPM tripping and a power trip error message.
- If the UPM does not trip, recheck the calibration connections and repeat the functional check.
- From the CSD, open the error log. Make sure the error log contains the message that the UPM has detected a power fault on Body Short Term Average.
- If the error is shown in the log, the functional test has passed. Click Yes on the dialog box.
- If the test fails, go to UPM troubleshooting.
