4 Open the Spectrum Analyzer view and maximize the view.
5 Select either Frequency or Channel in the Frequency Units.
Frequency is displayed on the Spectrum Analyzer view.
6 Set 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.
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.
NOTE
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.
