Follow the procedure in Table I-5 to perform the In-Service Calibration.
Table I-5: In-Service Calibration
Step Action
NOTE
Perform this procedure after test equipment has been allowed to warm-up and stabilize for a minimum
of 60 minutes.
1 Set up the LMF for In-Service Calibration:
- Start the LMF by double-clicking the LMF icon on the Windows desktop.
- Click Tools>Options from the menu bar at the login screen.
- Check the applicable spectrum analyzer check box and the signal generator check box on the Test
Equipment tab.
Ensure that the GPIB address is 18 for the CDMA analyzer and 1 for the signal generator.
- Uncheck any other other equipment that is selected.
- Click the Apply button.
- Select the BTS Options tab in the LMF Option window.
- Check the In-Service Calibration check box.
- Click the Apply button.
- Click the Dismiss button to close the LMF Option window.
2 Login to the target BTS:
- Select the target BTS icon.
- Click the Login button at the login screen.
3 Measure the Cable Loss using the Cable Calibration function:
- Click Util>Cable Calibration from the menu bar at the main window.
- Set the desired channel(s) and select TX and RX CABLE CAL at the cable calibration pop up
window.
- Click the OK button to perform cable calibration.
- Follow the on-screen instructions to complete the cable loss measurement.
NOTE
- The measured value is input automatically to the cable loss file.
- To view the cable loss file, click Util>Examine>Cable Loss>TX or RX.
4 Add the spectrum analyzer power delta to the Cable Loss.
- To view the cable loss file, click Util>Examine>Cable Loss>TX or RX.
- Add the value computed in Table I-1, Table I-2, or Table I-3 to the TX Cable Loss.
NOTE
Be sure to include the sign of the value. The following examples are included to show the mathematics
and do not represent actual readings:
- Example: 5.65 dBm + 0.55 dBm = 6.20 dBm
- Example: 5.65 dBm + (-0.29 dBm) = 5.36 dBm
- Example: -5.65 dBm + 0.55 dBm = -5.10 dBm
- Example: -5.65 dBm + (-0.29 dBm) = -5.94 dBm
