Radiometrics Midwest Corporation provides EMC and regulatory testing for telecommunications, wireless and network-connected electronic equipment at our A2LA-accredited EMC laboratory in Illinois.
Our telecommunications experience includes commercial and industrial communications equipment, intentional radiators, wireless devices, network equipment and products evaluated to FCC, ISED, ETSI and customer-specific requirements.
Telecommunications EMC Testing
Telecommunications equipment can require evaluation for both electromagnetic emissions and immunity as well as radio-transmitter requirements when wireless technology is incorporated into the product.
Radiometrics can coordinate multiple portions of a telecommunications EMC program, including:
- Radiated emissions
- Conducted emissions
- Radiated RF immunity
- Conducted RF immunity
- Electrostatic discharge
- Electrical fast transients
- Surge immunity
- Voltage dips and interruptions
- Intentional radiator testing
- Pre-compliance evaluation
- EMC troubleshooting and engineering support
The applicable test program depends on the product, interfaces, intended environment, radio technology and markets where the equipment will be sold.
Telecommunications Equipment
Radiometrics can support EMC and regulatory testing for a wide range of communications and network-connected products, including:
- Wireless communication devices
- Network and data communications equipment
- Base-station and infrastructure electronics
- Industrial communication equipment
- Remote monitoring and telemetry systems
- IoT and connected devices
- Equipment incorporating Wi-Fi or Bluetooth
- Short-range radio devices
- RF transmitters and receivers
- Communications modules and electronic subsystems
Testing can be performed on complete products or individual communications modules and subsystems depending on the applicable regulatory and customer requirements.
FCC Telecommunications and Wireless Testing
Radiometrics performs applicable FCC testing for telecommunications and wireless equipment.
Our capabilities include testing associated with FCC Part 15 as well as applicable licensed radio-service requirements.
Depending on the equipment and radio service, applicable FCC requirements may include Parts 22, 90, 95, 97 and 101.
Radiometrics can review the equipment, operating frequencies and intended application to help identify the appropriate FCC test requirements.
ISED Canada Telecommunications Testing
Radiometrics also performs applicable Innovation, Science and Economic Development Canada (ISED) testing for radio and telecommunications equipment.
Applicable requirements can include:
- RSS-Gen
- RSS-119
- RSS-130
- RSS-131
- RSS-210
- RSS-247
The applicable RSS specification depends on the radio technology, operating frequency, power level and intended application.
Wireless Device and Intentional Radiator Testing
Modern telecommunications equipment frequently incorporates Wi-Fi, Bluetooth, short-range radios, telemetry or other intentional transmitters.
Radiometrics performs FCC and ISED intentional-radiator testing for applicable wireless devices and radio technologies.
Testing can include transmitter emissions, restricted-band measurements, band-edge measurements and other requirements applicable to the radio technology and certification program.
European ETSI Testing
Products intended for European markets may require testing to applicable ETSI radio and EMC standards.
Radiometrics’ capabilities include testing associated with standards such as:
- ETSI EN 300 220
- ETSI EN 300 328
- ETSI EN 300 330
- ETSI EN 300 440
- ETSI EN 301 489 series
The applicable ETSI requirements depend on the radio technology, operating frequency and product configuration.
Telcordia / Bellcore Telecommunications Requirements
Radiometrics has experience with telecommunications-industry requirements historically associated with Bellcore and Telcordia.
These requirements may continue to appear in customer specifications, network-equipment qualification programs and legacy telecommunications documentation.
Radiometrics can review the specific Telcordia, Bellcore or customer telecommunications requirement and determine which tests can be supported by our laboratory.
EMC Immunity for Telecommunications Equipment
Network and communications equipment can be exposed to electrostatic discharge, RF fields, electrical transients, surges and conducted RF disturbances through power and communication connections.
Depending on the applicable product or customer standard, immunity testing can include:
- IEC 61000-4-2 electrostatic discharge
- IEC 61000-4-3 radiated RF immunity
- IEC 61000-4-4 electrical fast transient/burst
- IEC 61000-4-5 surge immunity
- IEC 61000-4-6 conducted RF immunity
- IEC 61000-4-8 power-frequency magnetic field immunity
- IEC 61000-4-11 voltage dips and interruptions
-
Detailed information about these immunity methods is available on our IEC 61000-4 EMC Immunity Testing page.
Radiometrics can coordinate these immunity requirements with emissions and applicable radio testing.
Radiated and Conducted Emissions
Telecommunications equipment containing digital electronics, processors, switching power supplies and high-speed interfaces can generate unwanted RF emissions.
Radiometrics performs applicable radiated and conducted emissions testing for FCC, CISPR, EN and other product requirements.
Testing can include representative operating modes, network activity, external cables, peripherals and support equipment when required by the applicable standard.
Pre-Compliance Testing
Pre-compliance testing can identify emissions, immunity or radio-performance problems before a product enters formal certification or qualification testing.
Radiometrics can perform focused engineering measurements to evaluate:
- Enclosure shielding
- Cable configuration
- Grounding and bonding
- Power-input filtering
- Interface filtering
- Antenna configuration
- Switching power supplies
- Digital circuitry
- Product operating modes
Design or configuration changes can often be evaluated during testing.
Telecommunications EMC Troubleshooting
If equipment fails an EMC or radio requirement, Radiometrics engineers can work with the manufacturer’s engineering team to characterize the problem and evaluate potential corrective changes.
Our combination of emissions, immunity and intentional-radiator testing allows multiple aspects of a telecommunications EMC problem to be investigated within the same laboratory.
