Integrated Wireless Test Architecture

A typical architecture starts from test software and connects instruments, RF path, shielding box, fixture and DUT. Interfaces such as JTAG, UART, Ethernet and GPIO are configured by project needs.

Programming + RF Test

Modern wireless production testing is often more than RF measurement. Programming, memory configuration, RF calibration, functional communication and traceability can be organized in one flow.

RF Signal Path & Calibration

One key issue in wireless test systems is that the signal seen by the instrument is not always the same as the actual DUT interface signal. The intermediate path needs loss, compensation and calibration consideration.

Transmitter Test

Covers project-supported capabilities such as transmit power, frequency, frequency offset and modulated signal verification.

Receiver Test

Uses controlled RF input to evaluate DUT receiving behavior under different signal conditions, limited to existing capability terms such as receiver sensitivity and packet loss.

RF Functional Test

RF performance and product function can be verified together, such as RFID range, antenna detection, Wi-Fi functional connection and remote server interaction.

Wireless Application Scenarios

The following summaries come from existing project evidence without duplicating full case content.

RFID

Parallel Production Test Architecture

For products suitable for parallel test, shared instrument resources, switching, multi-DUT fixture and parallel test sequence can build a multi-DUT architecture without promising fixed parallel count or takt improvement.

Test Fixture & Shielding

Fixture design needs to consider mechanical positioning, electrical interface, RF path, repeatability and production operation.
