RF System Theory

This interactive course is designed to ensure learners record proper RF signal levels and verify RF quality within the various upstream and downstream portions of the cable network. Learners will be able distinguish between key attributes, assignments and the technologies that use RF. Learners will differentiate between the time and frequency domain to identify how transmission lines affect RF. Finally, learners will identify how to use power splitters, filters, directional couplers and other RF passive devices correctly in the cable network.


Recommended
Prerequisites:

  • SCTE/ISBE Understanding Cable Technology
  • SCTE/ISBE Broadband Premises Installation and Services

Target Audience:

  • Customer Facing Installers
  • Customer Facing Technicians
  • Service Technicians
  • Customer Service Representatives
  • Field Operation Teams
  • Network Operation Center and related positions

Length:

Recommended online length to complete the training is 3 hours or ½ day onsite.

Requirements for Successful Course Completion: 

Module quizzes and course final 80% or higher (two attempts provided) 

Format and Schedule:

The course is delivered online via the SCTE/ISBE virtual classroom.

Online learners interact with web based course materials and complete assessments (quizzes) at a time that is convenient for them. Learners may also contact the instructor when they have questions.

Learners spend approximately 2 - 3 hours per week, on average, completing the various course activities in order to maximize the learning benefits. 100% of the schedule is determined by the learners (interacting with online materials, completing quizzes and a final exam).

Upon Successful Course Completion Participants will receive:

  • SCTE/ISBE Course Completion Certificate
  • 1 Recertification Units (RUs) toward SCTE/ISBE certification renewal

Course Modules:

  • Module 1 RF Foundations for Cable Networks
  • Module 2 RF Operation for Cable Networks
