Interference Analyzer
The Interference Analyzer (option 011) function is extremely effective for locating and
identifying periodic or intermittent RF interference. Interference signals derive from
several kinds of licensed or unlicensed transmitters that cause dropped calls and poor
service quality.
• Spectrum analyzer
– Sound indicator
– AM/FM audio demodulation
– Interference ID
– Spectrum recorder
• Spectrogram
• Receive signal strength indicator (RSSI)
• Interference finder
• Spectrum replayer
• Dual spectrogram*
Measurements
A spectrum analyzer capable of performing spectrum clearance, capturing just the
events where the received signal exceeds the defined power limit.
Audible Tone volume is proportional to the signal’s power strength. In addition, a
built-in AM/FM audio demodulator conveniently identifies AM/FM signals.
Interference ID automatically classifies interfering signals and lists the possible signal
types corresponding to the signal selected.
Spectrogram captures spectrum activity over time and uses various colors to differen-
tiate spectrum power levels.
The spectrogram is effective for identifying periodic or intermittent signals. Post-
processing analysis can be made for each measurement over time using a time cursor.
*Only available for the JD748A.
