Summary of ETSI EN 300 113 Testing for Land Mobile Services
This regulatory compliance testing covers the technical aspects of radio transmitters and receivers. These can be used in stations in the Private Mobile Radio (PMR) service. In the land mobile services, the testing operates on radio frequencies between 30 MHz and 1 GHz. This includes channel separations of 12,5 kHz, 20 kHz, and 25 kHz, intended for speech and/or data.
The ETSI EN 300 113 compliance testing method also applies to equipment for continuous and/or discontinuous transmission of data and/or digital speech.
The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder. Types of equipment covered by this document are as follow:
- Base station
- Mobile station
- Hand Portable stations
- Fitted with an antenna connector; or
- Without an external antenna connector but fitted with a permanent internal or temporary internal RF connector which allows access to the transmitter output and the receiver input.
Hand portable equipment without an external or internal RF connector is not covered by this document.
Scope of Equipment for RF Testing Purposes
Equipment being tested must fulfill the requirements of this standard on all frequencies over which the equipment is intended to operate. The manufacturer of this equipment will decide the frequency ranges, the range of operating conditions, and power requirements. These requirements are all applicable to establish appropriate test conditions.
Additionally, technical documentation and operating manuals must be supplied. Guidance from the manufacturer is given on the presentation of the equipment.
The manufacturer of equipment is responsible for providing one or more samples of equipment. Stand-alone equipment is to be complete with any ancillary equipment needed for testing. If a specific piece of equipment has several optional features, the test only needs to be performed on the equipment configured with the combination of features considered to be the most complex.
In the case of integral antenna equipment, it is acceptable to supply a second sample of the equipment if it does not have an internal permanent 50Ω connector.
Significance of the Mechanical and Electrical RF Device Testing
The equipment is designed, constructed, and manufactured to minimize harmful interference with other equipment and services. if un-properly adjusted, the controls may increase the interfering potentialities of the equipment being accessible for adjustment by the user.
The equipment must be marked in a visible place. The equipment must also be legible, tamper-proof, and durable. The marking must be following EC Directives and/or CEPT decisions or recommendations as appropriate.
The manufacturer may choose to have the equipment tested using bitstreams or messages. Methods of measurement using messages are generally more time-consuming.
ETSI EN 300 113 Testing Procedures and Conditions
In the case of combined full bandwidth analog speech and full bandwidth digital equipment, the following tests should be performed.
- Adjacent channel power.
- Unwanted emissions in the spurious domain.
- Transmitter attack time.
- Transmitter release time.
- Transient behavior of the transmitter
- Maximum usable sensitivity.
- Average usable sensitivity.
- Error behavior at high input levels.
- Co-channel rejection.
- Adjacent channel selectivity.
When specified, the transmitter under test is set to operate in continuous mode. If this is not possible, the measurements are carried out in a period shorter than the duration of the transmitted burst.
When measurements are made in discontinuous mode, the reported values can be average values. This is done using a set of measurements. Each of these measurements is made during or part of a burst.
The ETSI EN regulatory compliance testing conditions are generally performed under normal test conditions. The normal temperature conditions are to be within 15 to 35 degrees Celsius. The humidity conditions are set to be between the ranges of 20% and 75%.
