SBE ON-LINE ENGINEERING COURSES FOR MEMBER EMPLOYEES

RF101: Module 1 – Introduction to Radio Frequency (RF)            Length: 1 hour, 16 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

Join us for the first module of the new SBE RF101:Terrestrlal Transmission Systems course, Introduction to Radio Frequency (RF). The webinar includes: Definition of RF and Electromagnetic radiation and spectrum, Electric and magnetic fields, The Inverse Square Law and Attenuation of EM waves, Frequency bands and RF wave characteristics, Units of power: dB and dBm, History of RF, and Safety issues introduction: Exposure and limits.

RF101: Module 2, Transmission Lines                                                   Length: 1 hour, 15 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This is the second in an eight-part series that presents an overview of RF needed to understand and work with the RF end of the system. Join us for the RF101: Module 2 Transmission Lines. Taught by Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT, the webinar continues the RF101 training and discusses these topics: the definition and types of transmission lines; impedance and its importance to applications; losses associated with coax; wavelength considerations which impact the broadcast facility; return losses (including VSWR and standing waves), and power considerations of both coax and connectors.

RF101: Module 3, Towers, Antennas, and Transmission Systems   Length: 1 hour, 30 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This module continues the RF101 Series and covers these topics: transmission systems block diagram; common RF system components; antennas and terms; isotropic radiator; dipole and polarization; wavelength versus antenna size; variations on the dipole; and antenna gain introduction. This course is targeted at those with minimal or no background in RF and/or who are relatively new to the field. This eight-part series serves as a refresher for more seasoned engineers.

RF101; Module 4, Antenna Gain – Feed-Line Loss                          Length: 1 hour, 36 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

The information learned in Modules 2 and 3 focuses on this important discussion highlighting the relationship between gain and loss. Calculations and examples are discussed in these topics: coverage requirements; ERP versus TPO; review of directivity and gain; system losses; single radiator, multiple radiators, and other gain/loss calculations. This webinar continues the eight-part series that is targeted at those with minimal or no background in RF and/or who are relatively new to the field. This multi-module course will present an overview of RF needed to understand the basics and make informed decisions.

RF101: Module 5, Modulation Fundamentals                                 Length: 1 hour, 11 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This webinar covers the basics of the various modulation methods used in broadcasting.  The discussion begins with an overview of the communications model and progresses to the following: modulation definition, classes of amplifiers and efficiency; analog modulation principles of AM & FM; digital modulation principles; IBOC Radio; Digital TV; bit error rate function; forward error correction; constellation and eye diagrams; and signal and noise.

RF101: Module 6, AM, FM, TV RF Propagation                            Length: 1 hour, 15 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This introductory propagation webinar builds on the previous modules with further discussion of the various ways RF is propagated in the atmosphere.  The discussion includes the following: free space path loss; terrestrial propagation; predicted coverage and the aspects that can affect reception (such as terrain and interference); and a more in-depth look into AM, FM & TV signals.

RF101: Module 7, RF Test and Measurement                              Length: 1 hour, 16 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This introductory RF Test and Measurement webinar explores the common transmission measurements that engineers will be called upon to perform.  This includes – but is not limited to – frequency, power, occupied bandwidth, and modulation. Technical considerations specific to each test will be considered along with applicable FCC rules.  A brief look into antenna and feed-line measurements will furnish a better understanding of what to expect from a good operation transmission system.  Tests specific to AM, FM, and TV broadcasts are examined.

RF101: Module 8, FCC Regulations                                                Length: 1 hour, 15 minutes

Presenter: Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT

This introduction to FCC regulations explores the rules commonly applicable to broadcast facilities, which all engineers will be called upon to understand and apply. Sample topics include: Regulations: Friend or Foe?, Navigating the Maze, About the FCC, Checklists, Rules Common to All Services, AM specific, FM specific, and DTV specific.
