Tekiknow’s product Portfolio
EMC Testing solutions
The company provides end-to-end solutions for EMC testing, including application-specific EMC chambers, automation tools, NF scanners, supporting hardware, and transient immunity test setups.
EMC Chambers from Tekiknow
Tekiknow develops application-based EMC chambers covering radiated emissions, radiated immunity, and pre-compliance validation. The company’s EMC infrastructure focuses on validated RF performance rather than just chamber construction. Their chambers support shielding effectiveness up to 100 dB, extendable to 120 dB for high-performance environments, and are validated using NSA, sVSWR, TD sVSWR, and NSIL measurements to ensure consistent EMC measurement accuracy.
Compliant Chambers
Tekiknow makes 3m compliant EMC chambers in both semi-anechoic and fully anechoic configurations, along with a 10m compliant semi-anechoic chamber for large-scale EMC testing. The 3m chambers support emissions and immunity testing from 9 kHz to 18 GHz, extendable to 40 GHz, and comply with CISPR 16-1-4 and IEC 61000-4-3 standards. The semi-anechoic version uses copper-beryllium knife-edge shielded doors with validated NSA, sVSWR, and field uniformity performance, while the fully anechoic chamber uses full absorber coverage, including the floor, to minimize reflections and improve high-frequency measurement accuracy. Tekiknow’s 10m chamber supports 1m, 3m, 5m, and 10m test distances with quiet zones up to 4 meters, making it suitable for automotive, aerospace, defense, EV, and large industrial EMC validation.
Pre-Compliant Chamber
The Pre-Compliant Chamber is designed for rapid in-house EMC debugging and development-stage validation. It supports testing from 30 MHz to 18 GHz, with optional extension to 40 GHz. The chamber enables engineering teams to identify EMC issues during PCB, subsystem, and enclosure development before formal certification. Despite its compact footprint, it still supports shielding validation, NSA verification, and field uniformity measurements for meaningful pre-compliance analysis. Click here to learn more.
CISPR 12 Chamber
Tekiknow’s CISPR 12 Chamber is intended for radiated emissions testing of vehicles, boats, and engine-driven devices. The chamber is optimized to maintain low-noise RF conditions and stable site attenuation characteristics required for automotive and industrial EMC evaluations.

EMC Testing Automation Tools
Tekiknow offers three automation tools to enhance EMC testing accuracy, streamline compliance processes, and identify interference issues early in product development. These include Nexio’s EMC automation software, which supports automated emissions and immunity testing, instrument control, and standards-based workflows with integrated reporting and multi-vendor compatibility; Lumiloop’s laser-powered RF probes, used for field uniformity measurements and chamber calibration with improved stability and reduced interference; and Langer’s near-field scanning and PCB-level diagnostic tools, which enable localized EMI analysis, emission hotspot detection, and real-time debugging at the board and subsystem level before full compliance testing.
TEK-Near Field Scanner
Tekiknow provides robotic near-field scanners for localized EMI/EMC analysis at PCB and subsystem level during product development and pre-compliance testing. The system performs automated electric- and magnetic-field measurements using high-precision scanning probes to generate 2D and 3D RF emission maps for identifying hotspots, coupling paths, shielding leakage, clock noise, and switching interference directly on electronic assemblies.
The scanner supports automated vector measurements, real-time EMC analysis, high-precision robotic scanning, PCB impedance evaluation, and emission hotspot localization. These systems are mainly used for PCB EMC optimization, shielding effectiveness analysis, signal integrity troubleshooting, and early-stage EMC debugging before full chamber compliance testing.

Supporting Hardware
The company also provides supporting EMC chamber components such as RF shielded doors, antenna masts, turntables, antenna positioners, EMC cameras, low-dielectric test benches, and programmable RF attenuators for EMC and RF test environments. These components are designed to maintain shielding integrity, reduce RF reflections, support precise antenna positioning and DUT rotation, and enable real-time monitoring during emissions and immunity testing. Many of the systems use low-dielectric, non-reflective, and fiber-optic-controlled structures to minimize unintended electromagnetic interactions.
Transient immunity test setups
The company also provides EMC transient immunity test setups for evaluating how electronic equipment responds to electrostatic discharge, switching transients, voltage surges, magnetic fields, and power interruptions according to IEC 61000-4 standards. These setups include ESD, EFT, surge, magnetic field, and voltage dip testing systems integrated with ground reference planes, coupling/decoupling networks, surge generators, shielded grounding structures, and calibration equipment to simulate real-world electrical disturbances during EMC immunity testing.

Antenna Chamber
The antenna chamber from Tekiknows is a fully anechoic. It supports both far-field and near-field measurements and is used for applications including 5G, wireless communication systems, and next-generation network technologies. The chamber is constructed to provide a controlled, interference-free environment with shielding performance effective up to 40 GHz.
The chamber’s internal lining is covered with pyramidal anechoic absorbers. Specialized walkway absorbers are used on the floor, allowing physical access for setup and maintenance without affecting measurement conditions. Tekiknow also uses advanced polyurethane absorbers that help ensure accurate and reflection-free measurements. These absorbers are lightweight, customizable, and designed to perform effectively at high frequencies, making them suitable for long-term use across different antenna chamber designs.
The chamber supports testing from 800 MHz to millimeter-wave frequencies and follows established shielding verification standards such as IEEE-299 and EN 50147-1 (9 kHz to 18 GHz). It is equipped with precision antenna positioners offering up to 0.1° resolution and polarizers with 0.5° accuracy. The system is further supported by software and multi-axis positioning capabilities, enabling reliable testing of both passive antennas and active devices across research, commercial, defense, and space applications.
The chamber system is complemented by Tekiknows’ TEKPAT RF software, which supports automated measurement and reporting across antenna testing workflows. The software enables radiation pattern and frequency response measurements, along with the calculation of key parameters such as gain, radiation efficiency, total radiated power (TRP), and EIRP. It also provides visualization capabilities for 2D and 3D radiation patterns, with options to export data in formats such as CSV and generate structured test reports. With support for both active and passive device measurements, pre-certification and validation processes, and high-resolution measurements of up to 0.25°, the platform integrates closely with hardware, including switch matrices and vector network analyzers, ensuring a streamlined and precise testing environment for modern RF applications.
