System Tests 68P09255A57-2 The LFR requires an active external antenna to receive LORAN RF signals. Timing pulses are derived from this signal, which is synchronized to Universal Time Coordinates (UTC) and GPS time. The LFR can maintain system time indefinately after initial GPS lock. The HSO is a high stability 10 MHz oscillator with the necessary interface to the CSMs. The HSO is typically installed in those geographical areas not covered by the LORAN-C system.

Loss/Gain Offset 68P09255A57-2 Loss/Gain Offset Background Proper test equipment setup ensures that the test equipment and associated test cables do not introduce measurement errors, and that measurements are correct. NOTE If the test set being used to interface with the BTS has been calibrated and maintained as a set, this procedure does not need to be performed. (Test Set includes LMF terminal, communications test set, additional test equipment, associated test cables, and adapters.
Loss/Gain Offset 68P09255A57-2 Prerequisites A Serial Connection and a Network Connection tab are provided for test equipment selection. The Serial Connection tab is used when the test equipment items are connected directly to the CDMA LMF computer via a GPIB box (normal setup). The Network Connection tab is used when the test equipment is to be connected remotely via a network connection.
Loss/Gain Offset 68P09255A57-2 Automatically Selecting Test Equipment in a Serial Connection Tab When using the auto-detection feature to select test equipment, the CDMA LMF examines which test equipment items are actually communicating with CDMA LMF.

Adjusting for loss 68P09255A57-2 Adjusting for loss Introduction Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy. RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX. Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX slot.
Adjusting for loss 68P09255A57-2 CAUTION Always wear a conductive, high impedance wrist strap while handling any circuit card/module. If this is not done, there is a high probability that the card/module could be damaged by ESD.
Adjusting for loss 68P09255A57-2 - The second breakdown of the array is per sector. Three sectors are allowed. Table 3-39: BTS.
Adjusting for loss 68P09255A57-2 Example: C[1]=384, odd cal entry = 1 ‘‘calibration point” C[2]=19102, even cal entry C[3]=777, C[4]=19086, . . C[19]=777, C[20]=19086, (since only two cal points were calibrated this would be repeated for the next 8 points) When the BBX is loaded with BLO data, the cal file data for the BBX is downloaded to the device in the order it is stored in the CAL file. TxCal data is sent first, C[1] - C[60].
Adjusting for loss 68P09255A57-2 At sites WITHOUT RFDS option, BLO is approximately 42.0 dB ±4.0 dB. A typical example would be TX output power measured at BTS (36.0 dBm) minus the BBX TX output level (approximately -6.0 dBm) would equate to 42 dB BLO. The TX Bay Level Offset at sites WITH the directional coupler option, is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output minus BBX output level. Example: TX output power measured at RFDS TX coupler (39.
Adjusting for loss 68P09255A57-2 Single-Sided BLO Normally valid values are some value plus-or-minus some offset. If single-sided BLO” is selected, the result will only be considered a success if it’s in the lower half of the range. If it was normally success from 37-47 (which is 42± 5), single-sided BLO” would make it a success only if the result was from 37-42.
Adjusting for loss 68P09255A57-2 Table 3-41: BTS TX Path Calibration Step Action NOTE Selecting PILOT (default) performs tests using a pilot signal only. Selecting STANDARD performs tests using pilot, synch, paging and six traffic channels. This requires an MCC to be selected. Selecting CDFPilot performs tests using the CDF value for pilot gain and IS-97 gain values for all the other channels included in the Standard pattern setting (paging, synch, and six traffic).

Alarms 68P09255A57-2 Alarms The alarms testing should be performed at a convenient point in the optimization/ATP process, since the LMF is necessary to ensure that the RF cabinet is receiving the appropriate alarms from the power cabinet. The SC 4812ET is capable of concurrently monitoring 10 customer defined input signals and four customer defined outputs, which interface to the 50-pin punchblock. All alarms are defaulted to “Not Equipped” during ATP testing.
Alarms 68P09255A57-2 Table 3-54: Heat Exchanger Alarm Step Action 1 Turn circuit breaker “B” of the Heat Exchanger circuit breakers OFF. This will generate a Heat Exchanger alarm, ensure that the LMF reports the correct alarm condition in the RF Cabinet. 2 Alarm condition will be reported as BTS Relay #25 - “Heat Exchanger Alarm” makes contact. 3 Turn the circuit breaker “B” ON. Ensure that the alarm condition is now removed. NOTE The Heat Exchanger will go through the Start Up sequence.

Verify that the minor alarm LED (amber) is illuminated on the Meter Alarm Panel and the LMF reports this minor alarm. 2 Alarm condition will be reported as BTS Relay #24 “Minor Alarm” makes contact. 3 Turn the TCP power switch ON. The alarm condition should clear.

ATP Tests 68P09255A57-2 ATP Tests Introduction The Automated Acceptance Test Procedure (ATP) allows Motorola Cellular Field Engineers (CFEs) to run automated acceptance tests on all equipped BTS subsystem devices using the Local Maintenance Facility (LMF) and supported test equipment per the current Cell Site Data File (CDF) assignment. The results of these tests (at the option of the operator) are written to a file that can be printed.
ATP Tests 68P09255A57-2 In the unlikely event that the BTS passes these tests but has a forward link problem during normal operation, the CFE should then perform the additional TX tests for troubleshooting: TX spectral mask, TX rho, and TX code domain. NOTE Refer to Chapter 3 for detailed information on test set connections for calibrating equipment, cables and other test set components, if required.
ATP Tests 68P09255A57-2 TX/RX OUT Connections NOTE Table:note. Note 10pt Helvetica Many of the acceptance test procedures require taking measurements at the TX OUT (BTS/RFDS) connector. At sites with RFDS, all measurements are through the RFDS directional coupler TX OUT connector. ATP Test Procedure There are three different ATP testing options that can be performed to completely test a BTS. Depending on your requirements, one of the following ATP testing options should be run.
ATP Tests 68P09255A57-2 Individual Acceptance Tests The following individual ATP tests can be used to verify the results of specific tests: Spectral Purity TX Mask This test verifies that the transmitted CDMA carrier waveform, generated on each sector, meets the transmit spectral mask specification with respect to the assigned CDF file values.
ATP Tests 68P09255A57-2 ATP Test Procedure Table 4-1 describes the step-by-step procedures to run any APT Test. Table 4-1: ATP Test Procedure Step Action 1 Select the device(s) to be tested. 2 From the Tests menu, select the desired test. 3 Select the appropriate carrier(s) (carrier - bts# - sector# - carrier#) displayed in the Channels/Carrier pick list. To select multiple items, hold down the or key while making the selections.
ATP Tests 68P09255A57-2 NOTE TX output power is set to +40 dBm by setting BTS power level to +33.5 dBm to compensate for 6.5 dB increase from pilot gain set to 541. The calibrated communications test set measures and returns the attenuation level of all spurious and IM products in a 30 kHz resolution bandwidth with respect to the mean power of the CDMA channel, measured in a 1.23 MHz bandwidth, in dB, verifying that results meet system tolerances at the following test points: 1.
ATP Tests 68P09255A57-2 Background: Rho Test This test verifies the transmitted Pilot channel element digital waveform quality of each BBX2 carrier keyed up at a specific frequency per the current CDF file assignment. All tests are performed using the external calibrated test set controlled by the same command. All measurements are via the appropriate TX OUT (BTS/RFDS) connector. The Pilot Gain is set to 262 for each antenna, and all channel elements from the MCCs will be forward link disabled.
ATP Tests 68P09255A57-2 Background: Code Domain Power Test This test verifies the Code Domain Power/Noise of each BBX2 carrier keyed up at a specific frequency per the current CDF file assignment. All tests are performed using the external calibrated test set controlled by the same command. All measurements are via the appropriate TX OUT (BTS/RFDS) connector.
