Every capability is proven on real hardware before it enters the specification table. Planned features are labeled as such.
ABOUT RADILAB
From RF and electronics to measurement instruments that keep evolving
Wuxi Ruilei Electronic Technology Co., Ltd. was founded in 2019 in Wuxi, Jiangsu. We work on electronics and RF technologies and now focus on measurement instruments. FRA-100 is our first product.
WHO WE ARE
About Wuxi Ruilei Electronic Technology
We are an R&D-oriented company rooted in electronics and RF technology. Our background spans signal chains, analog front ends, RF circuits, and embedded systems; today we are converging that experience into a measurement-instrument product line.
FRA-100 is not a one-shot “finished product”; it is a platform built in stages. We first make two-channel gain/phase measurement reliable, then add impedance, calibration, and VNA. Each step is validated on real hardware, not just on a specification sheet.

HOW WE WORK
How we build products
Credibility in measurement comes from repeatable results, not from louder marketing.
Respect common-mode errors
Two-channel ratio measurement, narrow-band detection, and later calibration all aim to separate source, clock, cable, and fixture effects from the DUT.
Iterate hardware and software together
Analog front end, FPGA processing, host software, and calibration methods advance together, avoiding “hardware works, software doesn't”.
Label the stage honestly
Prototype, in development, and planned are clearly separated, so partners can judge maturity and risk.
CURRENT STAGE
Current stage: engineering prototype
We are turning the bench validation platform into a deliverable engineering prototype.
Working today
Two-channel stepped-sine gain/phase sweeps, FPGA digital down-conversion and single-bin DFT, 1 GbE SCPI, Windows host software, CSV/PNG export, and ADC overload detection.
In progress
Four-terminal vector-cancellation balanced bridge (HC/HP/LC/LP), impedance measurement, Open/Short/Load/Thru calibration, cable and fixture de-embedding, and full two-port VNA.
Next
Find real test scenarios and early partners to validate the prototype in filters, amplifiers, loop stability, and component measurements before finalizing the product configuration.
ROADMAP
Development roadmap
Every stage is validated on real hardware; timing may change with test results.
Proof of concept
Stepped-sine source, two-channel ratio measurement, and the FPGA processing chain.
