ETSI EN 300 390 Radio Equipment Using an Integral Antenna

ETSI EN 300 390 covers radio transmitter and receiver requirements used in Private Mobile Radio (PMR) services. 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 has a reputation for helping customers achieve their wireless product certifications. Our proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Keystone Compliance’s accurate test reports are delivered quickly using our “four-eyes” approach. Meaning that multiple technicians review each report, ensuring that all the information required is present.

Summary of ETSI EN Wireless Integral Antenna Testing

The ETSI EN standard test method applies to land mobile services, operating on radio frequencies between 30 MHz and 1 GHz. This includes channel separations of 12, 20, and 25 kHz, intended for data and/or speech.

ETSI EN 300 390 applies to service radio equipment intended for continuous and/or discontinuous transmission. The equipment comprises a transmitter and associated encoder. It also comprises a modulator and/or receivers and associated demodulator and decoders.

Integral Antenna: An antenna designed to be connected to the equipment. Additionally, the antenna does not use an external connector and is not considered to be part of the equipment. An integral antenna is fitted internally or externally to the equipment.

Before selling this device in global markets, the item must meet all compliance and regulatory requirements. The wireless technology device must also be marked in accordance with ED Directives and/or CEPT decisions. Lastly, this wireless testing and certification standard applies to combined analogue and digital radio equipment using an integral antenna. It is also intended for the transmission of data and speech. 

Scope of Wireless ETSI EN 300 390 Radio Equipment Testing

The frequency error of the transmitter is the difference between the measured carrier frequency in the absence of modulation and the nominal frequency of the transmitter.

Stand-alone equipment is complete with any ancillary equipment needed for testing. If equipment has several optional features, the test is only performed for the most complex feature.

The equipment being tested must be designed and built in accordance with good engineering practices. This will assist in minimizing harmful interference to other equipment and services.

Conditions of the Wireless ETSI EN Laboratory Test

The signal A-M3 is used as an unwanted signal for methods of measurement with either bitstreams or messages for measurements.

Generally, the test is performed under normal conditions. However, when stated, the test may be conducted under extreme conditions. The normal power source is replaced by a test power source capable of producing normal and extreme test voltages. The internal test power source must be low enough for its effect on the test results to be negligible.

Normal Test Conditions: The normal temperature and humidity conditions are done at the convenience of the manufacturer. These conditions are within the following ranges:

  • Temperature: +15 C to +35 C
  • Relative humidity: 20% to 75%

The normal test voltage for equipment connected to the mains is the nominal voltage. The frequency of the test power source corresponding to the AC is between 49 and 51 Hz. For operation from other power sources, the normal test voltage is declared by the manufacturer.

Extreme Test Conditions: For tests at extreme temperatures, measurements are made at the following upper and lower ranges:

  • -20 C and +55 C

Extreme test voltages for equipment connected to an AC mains source are to be the nominal mains voltage of 10%. Before measurements are made, the equipment reaches thermal balance in the test chamber. The equipment is then turned off during the temperature stabilizing period.
