Field Strength Measurements

All antennas have loss or gain that can cause errors in measurements. The Site Master can

correct for antenna loss or gain errors using Field Strength Measurements.

The antenna factors must be uploaded to the Site Master using the Anritsu Software Tools

provided with the unit. These antenna factors can then be used to correct for the measure-

ment error.

Step 1. Enter the antenna factor information for the specific antenna into the antenna ed-

itor of the Software Tools (see page 7-7).

Step 2.

On the Site Master, press the MODE key.

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

ENTER.

Step 4. Upload the antenna factors to the Site Master.

Step 5.

Press the SWEEP key and select the

MEASURE soft key.

Step 6. Select the

FIELD STRENGTH soft key from the measurement menu.

Step 7. Press the

SELECT ANTENNA soft key and use the Up/Down arrow key to select

the desired antenna factor file. Press the ENTER key to select.

The Site Master will now automatically adjust the measurement results based on the an-

tenna factors entered. A

FIELD STR icon appears to the left of the graph, and the antenna

name appears in the title bar at the top. All marker values are displayed in V/m.

Figure 5-3 shows the results of a measurement.
