From mmWave radar to electric drivetrains — complete coverage of modern automotive electronics validation
Rohde & Schwarz covers the full automotive test lifecycle, from design verification through type approval to volume production. KanTek is the authorized Taiwan distributor, providing selection consultation and local technical support.
The core test problems in modern automotive electronic systems
The fast evolution of automated driving, electrification and connectivity has put automotive electronics engineers in front of test challenges they have not faced before. The EU's 2035 phase-out of new combustion-engine cars is accelerating electrification worldwide, and Taiwanese Tier 1 suppliers are now under pressure on both export type approval and production throughput. These are the pain points the industry is dealing with today:
- Rising SAE automation levels (L2 → L4/5) drive a large increase in ADAS test coverage and safety requirements, and ISO 26262 and SOTIF call for broader sensor immunity validation
- Radar design specifications keep moving (higher resolution, massive MIMO, new bands) and there is still no unified industry standard, so test procedures have to be developed in house and executed rigorously
- Fast switching in SiC/GaN wide-bandgap semiconductors generates high-frequency EMI, and high-voltage electric drivetrains impose far stricter insulation, electrical safety and EMC requirements
- 5G, V2X, UWB, BLE and GNSS antenna systems are integrated into one vehicle at the same time and have to be validated for coexistence; component-level CISPR 25 testing alone no longer predicts the electromagnetic behavior of a powered-up vehicle
- In-vehicle networks are moving to multi-gigabit rates (Automotive Ethernet up to 10GBASE-T1), which compounds signal integrity challenges while TCU production test throughput has to rise in step
Five core automotive electronics test domains

End-to-end support for your automotive electronics test requirements
Long-Term Support Commitments
Production lines and R&D validation environments need measurement instruments that keep running for five to ten years. As the authorized Taiwan distributor for R&S, KanTek Technology offers the formal long-term support commitments below, so that your test equipment stays usable across the whole product lifecycle.
R&S states a minimum spare parts availability period of 10 years after a product is discontinued. KanTek Technology can help you write a priority spare-parts purchase clause into the procurement contract and hold a local buffer stock, reducing the risk that a critical component goes out of supply.
R&S operates an 18-month advance discontinuation notice. Once the notice is issued the last time buy (LTB) window opens, and during it you can secure enough replacement parts or instruments. KanTek Technology passes EOL notices on immediately and helps you size the LTB quantity and the budget.
Three-year, five-year and seven-year long-term service contracts (LTSC) can be quoted, covering scheduled preventive maintenance, annual calibration through a TAF-accredited partner laboratory, priority repair scheduling and technical support options. An LTSC can be tailored to the requirements of a particular procurement and signed in Chinese, which meets the Government Procurement Act's requirements for a local service contract.
KanTek Technology knows Taiwan's government procurement and corporate central purchasing processes, and supports automotive electronics OEMs and research institutes from requirement definition through to RFQ submission, compliantly and efficiently.
Some high-end R&S measurement instruments fall under US export control (EAR). KanTek Technology can help you confirm the ECCN classification, apply for the export license and supply a template for the end-use certificate (EUC) required, so that the procurement stays within export control rules.
KanTek Technology works with local partner laboratories in Taiwan that hold TAF accreditation (Taiwan Accreditation Foundation) and issue calibration reports to ISO/IEC 17025, satisfying government procurement acceptance and the measurement traceability requirements of IATF 16949.
Every inquiry, technical discussion and quotation document can be covered by a non-disclosure agreement at your request, which suits automotive electronics procurements involving confidential specifications and keeps the technical detail confidential throughout.
The industry partners who rely on KanTek Technology
One of Taiwan's five largest automotive electronics Tier 1 suppliers introduced the R&S FSW + ATS1500C mmWave radar validation chain in Q3 2024 and cut the UNECE R155/R157 certification cycle for its 77 GHz radar modules from 14 weeks to 6 weeks; in the same year the same company adopted the CMW500 for automotive LTE-V2X (PC5) protocol test and raised its first-pass rate from 68% to 94%. KanTek Technology provides local-language technical support, instrument calibration and — once the service launches — flexible rental terms, so that engineering teams can evaluate advanced test equipment at minimal risk.
