From "Cabinet Stack" to "Suitcase": A Technological Leap.

First Generation (Pre-2010):

Size comparable to a refrigerator. Required multiple engineers to operate collaboratively. A single test took approximately 8 hours.

Second Generation (Early 5G Era):

Modular design supporting Sub-6GHz frequency bands. Testing time reduced to 2 hours.

Third Generation (Modern Era)

Portable devices the size of a notebook. Capable of simultaneously testing mmWave + Sub-6GHz. Supports automated script testing

Future Trends:

Virtualized testing (replacing some hardware with software).

Pre-research on 6G terahertz frequency band testing technology.
