ANSI/TIA-603-E Testing of Land Mobile FM or PM Communications Equipment

ANSI/TIA 603 provides information on radio equipment used in the Private Land Mobile Services that use FM or PM modulations. As a leader in RF regulatory compliance testing, Keystone Compliance recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process.

Keystone’s proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Our wireless test engineers work with clients to quickly develop appropriate and concise test plans. Keystone is continually developing partnerships in GMA and RF exposure testing. These strategic partnerships allow us to meet customer needs beyond our scope of accreditation.

Summary of ANSI 603 E Testing of Land Mobile Wireless Devices

ANSI and TIA test method 603 defines measurements and the performance of radio equipment used in the private land mobile services. These devices use PM or FM modulation for the transmission of data using analog or digital techniques. Communication equipment often has a frequency of 1 GHz or less.

This standard applies to land-mobile equipment licensed under the FCC in the public safety, special emergency, and industrial radio services. TIA/ANSI 603 applies to equipment used by the government and falls under National Telecommunication and Information Administration (NTIA) rules.

Scope of ANSI/TIA 603-E Wireless Communication Equipment Testing

ANSI/TIA 603-E standardizes parameters, definitions, and test conditions used to determine the performance equipment of this wireless test method. ANSI/TIA testing compares the test results of measurements made by different observers or equipment.

There are two performance levels given in this wireless test method. Class A performance is recommended for private land mobile transceivers with enhanced interface protection characteristics. Class B performance levels are the minimum recommended levels for private land mobile transceivers.

ANSI/TIA Standard Lab Testing Conditions

The ANSI and TIA wireless equipment is generally assembled following the manufacturer’s instructions for the mode of operation being tested. When alternative modes of operation are available, the equipment is also adjusted and assembled for these modes. A complete series of measurements and tests are conducted for each mode of operation.

ANSI tests are conducted with associated equipment that is normally used with the unit under test installed. For mobile or portable equipment, the receiver, transmitter, control unit, and power supply are included in the installation process. The equipment must also function in the housing supplied with the equipment, where applicable.

Voltages used in this test standard are specified by the manufacturer. The voltage can not deviate from the stated value by more than ±2%. This is during the measurement of any one parameter, on any unit wider test.

For wireless equipment powered by batteries integral to the equipment, the standard test voltage is specified by the manufacturer. Test voltages can not exceed battery voltages after 10% of the rated battery capacity has been used.

The standard ac test voltage is equal to the nominal ac mains voltage to be applied to the equipment. If equipment is provided with different input voltage taps, the one designated nominal voltage is used.

Atmospheric conditions are conducted at a temperature of 25 degrees Celsius and an atmospheric pressure of 1013 hPa. Measurements are carried out at any combination of temperature, pressure, and relative humidity within the following limits:

  • Temperature: 20 to 35 Celsius
  • Relative Humidity: 45% to 75%
  • Atmospheric Pressure: 860 hPa to 1060 hPa
