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 <Shift> or <Ctrl> key while making the selections.
4 Type the appropriate channel number in the Carrier n Channels box.
The default channel number displayed is determined by the CdmaChans[n] number in the cbsc-n.cdf
file for the BTS.
5 If applicable, select Verify BLO (default) or Single-sided BLO.
NOTE
Single-sided BLO is only used when checking non-redundant transceivers.
6 For RX select the appropriate RX branch (Both, Main, or Diversity) in the drop-down list.
7 In the Rate Set box, select the appropriate data rate (1=9600, 2=14400, 3=9600 1X) from the
drop-down list.
NOTE
The Rate Set selection of 3 is only available if 1X cards are selected for the test.
8 In the Test Pattern box, select the test pattern to use for the calibration from the drop-down list: Pilot
(default), CDF, CDFPilot or Standard.
9 Click OK.
The status report window and a Directions pop-up are displayed.
10 Follow the cable connection directions as they are displayed.
11 Click Save Results or Dismiss to close the status report window.
If Dismiss is used the test results will not be saved in the test report file.
Background: Tx Mask Test
This test verifies the spectral purity 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 through the appropriate TX OUT
(BTS/RFDS) connector.
The Pilot Gain is set to 541 for each antenna and all channel elements
from the MCCs are forward-link disabled. The BBX2 is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only). BBX2 power output is set to obtain +40 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler).
