Microwave Link Troubleshooting using PCR Tool

Transmission engineering


PCR reports a countless variety of microwave transmitter, receiver, and traffic data responses to a multitude of combinations of: Transmitter and receiver alarms, Flat and dispersive multipath fades, Power fades caused by rain and ABL (Atmospheric Boundary Layer) duct-generated signal entrapments, Radio module behavior, Maintenance activity, Antenna misalignments, Non-optimum space and frequency diversity separations, Effects of the path’s geo-climatic conditions, Interference, etc.

The PCR courses are conducted by AVIAT expert trainers in a mentoring environment backed by their deep technology expertise and experience in implementation of microwave wireless and IP networks.

The PCR course is conducted at Aviat Training locations or can be arranged at customer sites.

Upon successfully completing this course, participants will be able to:

  • Use the PCR tool to troubleshoot microwave links
  • Solve the most frequently encountered microwave link problems using the analysis performed with the PCR tool
  • Analyze microwave propagation events
  • Better understand the effects of the environment on microwave frequencies
  • Perform basic path analysis
  • Correlate RSL hits to propagation events
  • Interpret basic PCR readings
  • Describe common RF problems
  1. Microwave transmission engineering experience
  2. Microwave link design experience
  3. Attendees are encouraged to bring their system-specific PCR data for analysis in the workshop
  4. PathLoss V.4 or V.5 is required to complete the tasks associated with the course
  5. Each student must bring an IBM compatible laptop PC and have administrator rights on the PC (to allow installation of the Portal craft tool).The PC must have minimum parameters of:
    • Pentium 4 or later w/ 1GB of RAM and 250 Mb of free hard drive space.
    • Microsoft Windows XP, Vista, 7 or Windows 10.
    • USB Port
    • Network adaptor port (LAN Port)
    • DB9 serial port connection or adapter (optional)

Course outline

  • Atmospheric effects – mixed and layered
  • Terrain effects – scattered and specular
  • Fade mechanisms:
  • Multipath fades – reflective and refractive
  • Power fades – antenna decoupling, wave front defocusing, path obstruction; rain depolarization
  • Dispersive fades – spectrum distortion
  • Interference issues – co- and adjacent-channel
  • EMI issues – site noise, feeder system contamination, spurious radar and LMR interferences, oTE11 mode conversion
  • Error migration via muxless repeaters
  • Protection schemes and diversity arrangements
  • Link impairment mitigation
  • PCR overview – analog traces, radio status, radio and traffic alarms,
  • Extracting PCR performance data
  • Reading and interpreting PCR data
  • Path and Performance analysis
  • Case study
  • Path analysis
  • Performance data analysis
