NOTE:
You can choose RF Source On or Off in setup menu after tap to CAA RF Power On if you have RF Source option
in your CAA(Cable and Antenna Analyzer).
Conducting spectrum measurements
Spectrum
Most spectrum measurements of the interference analyzer are also available in Spectrum mode. Using these measurements allow
you to locate interferences in the frequency spectrum. You can configure the measurements just as in Spectrum mode. For more
information see "
Configuring spectrum measurements ".
The spectrum measurement with an audible indicator is especially useful for locating interferer sources with a directional antenna.
Setting measure setup for sound indicator
1 Tap the Setup ( ) icon on the side bar.
2 Tap Sound Indicator .
a Tap to switch the Sound between On and Off to enable and disable the alarm sound.
b Tap to switch the Alarm Reference to Marker to set the active marker position as the alarm reference.
c Tap to switch the Alarm Reference to Line to set the limit as the alarm reference.
The Reference Line Mode menu becomes activated to be set.
d Select Reference Line to specify a threshold for the reference line using the on-screen keyboard.
e Optional. To adjust the volume for alarm sound, tap Volume and input from 1 to 10 using the on-screen keyboard.
Setting measure setup for Interference ID
The Interference ID automatically classifies interfering signals over a designated spectrum and displays the list of possible signal
types corresponding to the selected signal.
1 Tap the Setup ( ) icon on the side bar.
2 Tap Interference ID .
a Tap to switch the Interference ID between On and Off to turn the Interference ID on and off.
b Tap Threshold and input a value using the on-screen keyboard.
NOTE:
You can go to Menu > Limit to analyze your measurements with the display line, multi-segment line, and channel
limit table. See “
Setting limit " for details.
Spectrogram
The Spectrogram is particularly useful when attempting to identify periodic or intermittent signals as it captures spectrum activity
over time and uses various colors to differentiate spectrum power levels. When the directional antenna is used to receive the signal,
you will see a change in the amplitude of the tracked signal as you change the direction of the antenna and see a change in the
Spectrogram colors. The source of the signal is located in the direction that results in the highest signal strength.
