RF & Wireless Test

RF & Wireless Automated Test Solutions

RF & Wireless Automated Test Solutions are designed for Wi-Fi, Bluetooth, NB-IoT, RFID, RF modules, antenna/amplifier and automotive RF/V2X products. The solution integrates fixture, shielding and RF path, instrumentation, programming, RF measurement, functional test, test software and production data into a complete automated test system.

Customer Challenges

  • Wireless production testing often involves RF measurement, functional communication, online programming, fixture positioning, shielding environment and data traceability.
  • The signal seen by the instrument can differ from the actual DUT interface signal because of cable, connector, switch, fixture and shielding-interface paths.
  • Some products require a parallel test architecture, but the parallel count, fixture structure and sequence must be designed based on DUT and project constraints.
  • RF performance testing and product functional testing need to be combined, so the solution is not simply an instrument feature page.

Solution Approach

  • Build a typical system chain from test software to RF instrumentation, RF switch/cable, shielding box, test fixture and DUT.
  • Use project interfaces such as JTAG, UART, Ethernet and GPIO for DUT identification, programming, configuration, communication and functional validation.
  • Design RF path calibration, path-loss compensation and calibration flows based on project needs without publishing unverified dB accuracy or frequency range.
  • Organize RF measurement, functional test, production records, reports and traceability in unified test software.
  • Use existing Wi-Fi, RFID, antenna amplifier and V2X engineering cases as project evidence without creating customer stories.
