Antenna System Calibration Equipment Required
7. Select the uplink band (quadrant) in which the test transmitter is programmed. The
choices are 1, 2, 3, or 4.
8. Right click on the detected TIM PCI card.
9. Select Open. The PCI Device Window will open (shown in FIGURE 4-2).

10. Enable power for the antennas:
11. Click on the change button located under the Transmitter window. Scroll down to and
select DL_EN_BOTH_ANT.
12. Verify both the Main and Div Ant "LEDs" are both illuminated.
13. Press the Update Now button. Check the antenna current for the main and diversity
branches. Each antenna should draw approximately 135 milliamps. Multiply that
number by the number antennas connected to each branch. Determine if the
appropriate current measurement is displayed. (with no antennas connected the current
measurement will be approximately 65 ma.)
14. Scroll down to the channel that corresponds to the frequency of the test transmitter.
4.1.1 Setting a Reference Signal Level
1. Connect the RF attenuator(s) to the SMA connector on the test transceiver.
2. Connect the SMA to BNC adapter (P/N 0454-00-0041-XX) to the test Transceiver.
3. Connect to test transceiver to the Main (A) input connector on the TIM Transceiver.
NOTE: The signal level (RSSI) displayed for the test transceiver. The
signal should not exceed -40 dbm. Add additional
attenuators if necessary.
