Chapter 5 Spectrum Analyzer Measurements

Procedure

Using the test port extension cable and 30 dB attenuator, connect the Site Master to the RF_IN test port. The measurement can be accomplished with or without the 30 dB attenu- ator. The attenuator is recommended for additional protection.

Step 1. Press the ON/OFF key on the Site Master.

Step 2. Press the MODE key.

Step 3. Use the Up/Down arrow key to select the Spectrum Analyzer mode and press

ENTER.

Step 4. Enter the following control settings: reference level = –15 dBm Scale = 10 dB/division

RBW = 10 kHz

VBW = 30 kHz or greater Span = 2.5 MHz

Step 5. Press the MEAS key.

Step 6. Once in the MEAS menu, press the CHANNEL POWER soft key.

Step 7. Select the center frequency by pressing the CENTER FREQ soft key and enter 900 MHz as the center frequency of the CDMA signal.

Step 8. Select the integration bandwidth by pressing the INT BW soft key and enter 1.23 MHz for the integration bandwidth.

Step 9. Select channel span by pressing the CHANNEL SPAN soft key and enter 1.23 MHz as the desired integration bandwidth.

Step 10. Make the measurement by pressing the MEASURE soft key. The Site Master will display the measurement results in the display area.

Integration bandwidth is defined as the frequency span in which the spectrum analyzer inte- grates measured power readings.

Channel span is the frequency range the analyzer sweeps. Channel span must be set to equal or greater than the integration bandwidth, or the Site Master will by default set the channel span equal to the integration span. The Site Master also keeps the ratio of the integration bandwidth to channel span constant. For example, if the channel span is doubled, the Site Master will double the integration span.

When the integration bandwidth and channel span are set to the same value, the Site Master provides the most accurate measurement, as it uses all the sampling points for integration.
