ATP Test Procedure

Follow the procedure in Table 4-1 to perform any ATP test.

Table 4-1: ATP Test Procedure

Step Action

1 Be sure that all prerequisites described on page 4-5 have been met.

NOTE

If the LMF has been logged into the BTS with a different Multi–Channel Preselector setting than the

one to be used for this test, the LMF must be logged out of the BTS and logged in again with the new

Multi–Channel Preselector setting. Using the wrong MPC setting can cause a false test failure.

2 Select the device(s) to be tested.

3 From the Tests menu, select the desired test from the pulldown menu:

– All TX/RX ATP... / All TX ATP... / All RX ATP... or

– TX > (TX Mask... / Rho... / Pilot Time Offset... / Code Domain Power...) or

– RX > FER...

4 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.

Verify that the correct channel number for the selected carrier is shown in the Carrier # Channels

box. If it is not, obtain the latest bts–#.cdf (or bts–#.necf) and cbsc–#.cdf files from the CBSC.

NOTE

If necessary, the correct channel number may be manually entered into the Carrier # Channels box.

6 If applicable, select Verify BLO (default) or Single–sided BLO.

NOTE

Single–sided BLO is only used when checking non–redundant transceivers.

7 For RX select the appropriate RX branch (Both, Main, or Diversity) in the drop–down list.

8 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 1 is only available if non–1X cards are selected for the test.

The Rate Set selection of 2 is only available if non–1X cards are selected for the test.

The Rate Set selection of 3 is only available if 1X cards are selected for the test.

9 Enter the channel elements to be tested for the RX ATP in the Channel Element(s) box. By default,

all channel elements are specified.

Use one of the following methods to enter more than one channel element:

– Enter non–sequential channel elements separated by a comma and no spaces (for example;

0,5,15).

– Enter a range of sequential channel elements by typing the first and last channel elements

separated by two periods (for example; 0..15).

NOTE

The channel element numbers are 0 based; that is the first channel element is 0.
