ETSI EN 300 220-1 EMC Radio Spectrum Short Range Devices
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 Compliance actively engages in the TCB Council, ANSI C63 Main Committee, and ANSI C63 wireless working groups.
Keystone’s RF testing lab takes pride in providing the peace of mind that all of your wireless testing needs will be met. Additionally, we are in constant communication throughout the entire test process. Keystone Compliance is continually developing partnerships in GMA and RF exposure testing. These strategic partnerships allow us to meet customer needs beyond our scope of accreditation. Our radio testing engineers streamline the process and assist companies to achieve the compliance they require.

Summary of ESTI EN 300 220-1 Wireless RF Compliance Testing
This wireless products testing applies to the following short-range device major equipment types:
- Non-specific short-range devices.
- Alarms, identification systems, radio-determination, telecommand, telemetry, etc.
- Radiofrequency identification.
- Detection, movement, and alert applications.
These radio equipment types are capable of operating in certain frequency bands. These bands include 25 MHz to 1,000 MHz.
- Either with an RF output connection or dedicated antenna or with an integral antenna.
- For all types of modulation.
- With or without speech.
Scope of ETSI EN 300 220-1 Technical Requirement for RF Lab Testing
The product family for short-range devices is divided into three categories. Each category has a set of relevant receiver requirements. The set of receiver requirements depends on the choice of receiver category by the equipment provider.
When designing SRD, manufacturers must choose one of the three receiver categories. These are according to the grade of operational reliability they provide. Therefore, the provider must specify the receiver category and declare it within the product literature.
For this intentional radiator performance test, the receiver produces an appropriate output under normal conditions as shown below:
- A SINAD ratio of 20 dB. Measured at the receiver output through a telephone weighting network.
- After demodulation, a data signal with a bit error ratio of 10-2without correction.
- After demodulation, a message acceptance ratio of 80%.
- An appropriate false alarm rate, or, sensing criteria declared by the provider.
Each equipment submitted for testing should fulfill the requirements of the ETSI EN 300 220-1 standard on all frequencies over which it is intended to operate. Testing is carried out on the highest and lowest frequencies within the equipment’s intended operating range.
If a piece of equipment is designed to operate with different carrier powers, measurements of each transmitter are performed at the highest power level. A test fixture for equipment with an integral antenna may be supplied.
To simplify the RF device testing process, measurements are performed according to the document on samples defined in the document’s specific clauses. These clauses are intended to give confidence that the requirements have been met without the necessity of performing measurements on all frequencies.
ETSI Electromagnetic Compatibility Testing Conditions
Intentional radiator requirements state that the testing equipment may be made under normal or extreme test conditions.
Normal test conditions such as temperature and humidity are done conveniently within the ranges of 15-35 degrees Celsius and 20% to 75% relative humidity. When it is impractical to carry out tests under these conditions, the ambient temperature and humidity are stated in the test report.
Extreme testing condition measurements are made following the procedures specified at upper and lower temperatures. The temperature range is declared by the provider. The temperature range may also be conditioned to general, portable, or normal indoor ambient temperatures.
