Test Configuration
Before the Test Software can perform automated Base Station testing, it must have
available certain information regarding test conditions. Supply this information on the
Test Configuration Menu screen.
Configure the test as follows:
Step 1. Select the Test Config uration field. The Test Software will display the Test
Configuration Menu (see Figure 2-10).
Figure 2-10 Specifying Test Configuration Information
Step 2. Select the REF IN Connected to field and select the source of the input signal from the
drop-down Choices: list. The selections are: SCT (J2) [16 X Chip] (typically, the
19.6608-MHz clock from one of the cell site SCT modules) or GPS [10 M Hz], which is
from a GPS receiver.
Step 3. Select the Base Statio n Connect ion field and select the test port to be used in the
measurement from the drop-down Choices: list. The selections are: TX Ant enna Por t
(which supplies the transmitter power directly to the antenna) or TX Test Por t (which
comes from a directional coupler in the transmitter output).
Step 4. Select the Code Domain Averages field, rotate the knob to the desired value, then press
the knob to select it. Choose this value carefully. More data samples when averaging
measurements will increase testing time, but will reduce the effects of small level
changes, thus producing higher consistency and providing a higher confidence level for
the test results.
Step 5. Select the Walsh Code Power Uni ts field and select the units in which the Walsh code
power will be displayed from the drop-down Choices: list. The selections are: dBt, dBm,
and Watts. The unit “dBt” refers to the power of a Walsh code relative to the total
measured channel power. The units dBm and Watts are measurements of the absolute
power for a Walsh code.
