of the unit, and the DUT fixture is made of electromagnetically transparent material. The design
ensures an optimal measurement environment.
The system is composed of a shielding enclosure with absorbing material, positioner, ODC
baseband test module, mmWave frequency convertors, RF link, test automation software, and
other auxiliary modules. A system block diagram is shown in Figure 2.

Each RN200 module is described as follows.
1.
The baseband test module ODC200 VSG/VSA, designed for vector signal generation and
analysis, is ideal for 5G non-signaling FR1/FR2 testing. Its multiple RF input/output
channels support the real parallel test, which can improve test efficiency and significantly
reduce the test cost. Meanwhile, this module’s control interface is based on an open
design, where users can generate and analyze arbitrary signal waveforms.
2.
The mmWave frequency converter is used for testing mmWave devices. It upconverts
signals from 4GHz~5GHz to 24GHz~43.5GHz and vice versa. Users can test mmWave
devices’ performance without using any additional mmWave test instrument. The
mmWave frequency converter provides up to a 40dB power adjustment range and helps
to control the measured signal level to be within a reasonable range.
3.
The shielded enclosure, also known as the microwave chamber, is mainly used to isolate
electromagnetic signals, create a closed electromagnetic environment, provide a
