Select and Run the Test
Perform the Emission BW & Spurious Test as follows:
Step 1. From the Lucent CDMA Tests Main Menu screen, select the Test Selections field. The
Test Software will display the Test Selections Menu screen.
Step 2. Select the Emission BW & Spurious Test field.
Step 3. The Test Software will display instructions regarding test results. Read the instructions,
then press the
k1 (Proceed) key.
Step 4. Enter the “Percentage” of total power in the span. This will be used to determine the
emissions bandwidth. The default is 99 percent.
Enter the spectrum analyzer frequency “Span” in which to perform the Emissions
Bandwidth Test. The default is 1.499 MHz.
Step 5. Follow the displayed instructions and diagram to make the measurement for the
Spurious Emissions Test.
NOTE This procedure includes steps that prompt you to disconnect cables from the site antenna
ports and make connections to the Test Set. Before removing or re-installing the antenna
cables, make certain that the transmitter has been turned off by the MSC (or by switch
personnel if not using a modem). The green ACT LEDs on the ACU and BCR modules
indicate the transmitter is active, and therefore should be off before disconnecting
cables.
Step 6. The Test Software will begin running the spurious emissions test. At the end of the test,
a short summary of results will appear on the display. A complete listing of the spurious
emissions measurements and the results will be sent to the BTS Laptop Utility program
Test Results window.
Step 7. Press the
k1 (Proceed) key to start the Emissions Bandwidth Test. The test results will
appear on the Test Set display and also in the BTS Laptop Utility program Test Results
window. Press the
k1 (Proceed) key after viewing the screen. The final screen will
display re-configuration information. Press the
k1 (Proceed) key again to return to the
Test Selections Menu screen.
