Pathrrot X2

Channel Emulator

Pathrrot X2 channel emulator is the latest wireless measurement instrument launched by Transcom Instruments, which is oriented to the emulation for 4G/5G channel environment. It widely supports all kinds of MIMO channel models and has excellent RF performance, rich channel models, and friendly user experience etc. As a substitute of traditional field testing, the channel emulator can easily simulate the real world wireless propagation in the laboratory (i.e., virtual field test) by using real-time emulation capabilities of the instrument.

Pathrrot X2 provides a very effective means for the performance test of base station and user terminals, and it also builds a convenient test environment for the R&D of technologies and commercial products.
