How to Create a Part 15B Report
2
What is Part 15B?

• Part 15B is the traditional Unintentional
  Radiator section of the Rules.
• Devices which fall into this category include
  Computers, Computer Peripherals and Radio
  Receivers which operate at less than 960MHz

3
What is an Unintentional Radiator

• Devices such as radio receivers and computers
  produce incidental radio frequency noise as a
  characteristic of their operation.
• They are never designed to use radio energy for
  either communications (Licensed or Unlicensed
  Transmitters), or for work (ISM equipment)

4
Building a Test Report

• All Part 15 filings use ANSI C63.4 as a guide for
  building Test Reports.
• See Section 10 for general report requirements.
• Details of the measuring equipment and OATS are
  required.
• Photographs of the Test Setup are necessary.

5
Required Exhibits

• AmericanTCB has its own easy-to-use application
  form in MS Word format for use in all filings. A
  completed Application is required before any work
  can proceed.
• In addition to the Test Report a number of
  specific Exhibits are required.

6
Exhibits which accompany all filings

• Label
• Internal Photographs
• External Photographs
• Cover Letters
• Operational Description
• Schematics
• Block Diagrams
• Manual
• Test Setup Photographs
• Can be held Confidential

7
Basic Exhibit Requirements

• All Exhibits, including the Test Report must be
  under 4MB in size
• Although a wide variety of file types are
  accepted by the Commission, we strongly recommend
  converting to .pdf format

8
Label

• Label drawing or photograph must be clear and
  readable
• Must show FCC ID
• Must show location on the product.
• Must include required regulatory statements.
• Some exceptions are allowed when the device is
  very small. Check for details with ATCB

9
Internal Photographs

• Must show top and bottom of all circuit boards
• Must be clear and easily readable
• Must show layout details
• Must show unusual construction details
• Ideally, large and one-to-a-page

10
External Photographs

• Must show all external controls
• Must show all ports and connections
• Must show top, bottom, and all sides of device.
• Orthographic projection preferred
• Ideally, large and one-to-a-page

11
Cover Letters

• A letter describing a reason for this Application
• A letter allowing the laboratory to act on behalf
  of the Applicant
• A Confidentiality Request letter, if desired,
  requesting that certain Exhibits be kept away
  from public view at the FCC website.
• Details and examples available from ATCB

12
Operational Description

• An operational description is ideally an
  engineering description of how the device works.
• Simplified descriptions are acceptable if dealing
  only with common, everyday devices.
• Can be held Confidential

13
Schematics

• These are complete electrical line drawings or
  diagrams of how a device is assembled.
• Circuit board layout diagrams are not needed or
  required.
• Must be clear and easily readable
• Must show component values
• Can be held Confidential

14
Block Diagram

• Different from a schematic
• Shows the major operational components and how
  they are interconnected
• Must show frequency and signal paths
• Should match Operational Description
• Can be held "Confidential

15
Manual

• Cannot show how to operate the device in a manner
  which violates FCC rules.
• Must have required regulatory information
• Preliminary drafts are acceptable.
• The required regulatory information is complex
  and device specific. Please check with ATCB for
  details.

16
Test Setup Photographs

• Must be provided as a separate Exhibit and not
  buried within the Test Report document.
• Must show highest radiated emissions setup
• Must conform to ANSI C63.4 requirements
• Must provide separate AC Conducted and Radiated
  Spurious teststups
