ETSI EN 300 330 Short Range Device Wireless Testing

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 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. Our proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Keystone takes pride in providing the peace of mind that all of your wireless testing needs will be met.

Summary of ETSI EN 300 330 RF Testing

This ETSI EN 300 330 document applies to the following short-range device major equipment types:

1. Generic short-range devices including transmitters operating in the range from 9 kHz to 25 MHz.
2. Inductive loop transmitters operating from 9 kHz to 30 MHz. This includes Radio Frequency Identification (RFID) and Electronic Article Surveillance (EAS) operating in low and high-frequency ranges. 
3. Receivers of systems as defined above by bullets 1 and 2.

These radio equipment types are capable of operating in the permitted frequency bands of 9 kHz to 30 MHz:

• Either with a Radio Frequency (RF) output connection and dedicated antenna or with an integral antenna.
• For all types of modulation.
• Receivers of systems as defined by the bullets above.

This document covers fixed stations, mobile stations, and portable stations. If a system includes transponders, they are measured together with the transmitter. If the requirements from the clause mentioned above are met, all types of modulation for radio devices are covered in this document.

There are three types of RF device testing measuring methods. These are due to the varied nature of the antenna types for equipment used in this band. One wireless regulatory compliance method measures RF carrier current. Another measures the radiated H-field. Lastly, the third RF compliance method measures conducted power.

Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).

Testing Parameters of ETSI EN Intentional Radiator Equipment Testing

The product family of short-range radio devices is divided into three receiver categories. Each wireless telecom device has its own set of minimum performance criteria. This classification is based upon the impact on persons in case the RF lab equipment does not operate above the specified minimum performance level.

Each equipment submitted for testing should fulfill the requirements of this document. This includes all frequencies over which it is intended to operate. The provider shall declare frequency ranges to establish appropriate RF laboratory testing conditions. These may range from operating conditions and power requirements.

If the equipment is designed to operate with different transmitter radiated field strengths or power levels, each transmitter parameter is measured on samples of equipment.

The wireless product provider is recommended to prepare one or more samples of the equipment, as appropriate for testing. Stand-alone equipment is to be offered by the provider complete with any ancillary equipment needed for testing.

The performance of the equipment submitted for testing is representative of the performance of the corresponding production model.

The equipment is tested using the appropriate test power source. Where equipment can be powered using either external or internal power sources, the equipment is tested using external power sources as specified below.

During the RF testing lab procedures, the power source of the equipment is replaced by an external test power source capable of producing normal and extreme test voltages. For the intentional radiator requirements, the voltage of the external test power source is measured at the input terminals of the equipment.
