Doing UPM functional check for body channel 1

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

  1. Make sure the RF enable switch is in the DISABLE (down) position.
  2. For body channel 1, disconnect J4 and J22 and connect the dummy load to J4 and connect the 3/16 inch wavelength stub cable to J22.

  3. Set the RF enable switch to the On position.
  4. Press Landmark. Then, advance to scan. A phantom is not needed.
  5. On the Common Service Desktop, from the Calibration menu, select Calibration > Calibration Wizard and select Click here to start this tool.
  6. (For non-proprietary mode) on the Common Service Desktop, from the Calibration menu, select Calibration > UPM Tool and select Click here to start this tool.
  7. Select RF/UPM Cal & Functional Check (Body) and select Click here to start this tool.
  8. note: Be sure to check the resistance as noted in the Dummy load resistance check and setup procedure, prior to starting the UPM functional check.
    In the UPM tool, make the following UPM functional check selections:

    RF Chain Body Channel 1
    note: The Power Type drop-down menu is inactive for this step.
  9. Click Start.
  10. Click Yes when the prompt asks if the hardware setup is correct.
  11. Review the system prompts as they are displayed 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.
  12. 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.
  13. 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 displayed in the log, the functional test has passed. Click Yes on the dialog box.
  14. If the test fails, go to UPM troubleshooting.
