Preparing the software

1Start the E6474A software.

2Refer to“Identifying devices" on page 81, and perform the procedure if you have not already done so.

3Click Log > Start Live Mode.

4Open the Spectrum Analyzer view and maximize the view.

5Select either Frequency or Channel in the Frequency Units. Frequency is displayed on the Spectrum Analyzer view.

6Set the measurement controls as follows: Band: Downlink

Frequency: User-specified. The frequency you specify and enter in the Center field should be a known communication frequency or channel.

Span: 2 MHz or 1 MHz, depending on the channel used

Averaging: Running

Averages: 32

Testing the signal

In the Markers group, click Add and To Max. The level and frequency are displayed at the top-left corner of the Spectrum Analyzer view.

Wait for at least one minute before using the displayed marker value. The system is set to display a running average of 32. With time, the marker value will approach the value of the measured signal.

Passing the test

If the signal trace is of acceptable amplitude above the noise floor, depending on the distance from transmitters and antenna placement, at the appropriate frequency for the channel measured, the system passed the test.
