Test Performance
The static zone performance of the RP system is one of the core indicators of the constriction field system. The RP system has the leading international static zone performance, and has the leading international / domestic core technology in system simulation design, feed source, reflective surface, absorbing material, turntable and static zone testing equipment.
The efficiency of the test system stems from a deep understanding of the user’s needs and the part under test, and a continuous improvement in test efficiency on the basis of meeting the customer’s test accuracy requirements, until the perfect balance of efficiency and accuracy is achieved.
Core Technologies
1. Uniform-Phase-center Feed
Compared to traditional corrugated horn feeds, GTS’s CATR horn feeds exhibit excellent wide-angle cross-polarization performance, with phase center deviations on the E-plane and H-plane being less than 5° , and VSWR less than 1.5. In the whole system simulation, the cross-polarization testing accuracy has improved nearly three fold, and the phase testing accuracy has increased by approximately 20%.

2. Low Edge Scattering Reflector
Reflective surface for wave absorbing surrounds
3. Low-scattering high-precision Positioner
GTS has expertise in precision electromechanical technology, combined with full-wave system simulation, self-developed absorbing materials, and microsecond-level continuous triggering technology. This combination ensures system mechanical precision while reducing positioner interference to the test zone, The accumulated error of bidirectional tests is zero, doubling the testing efficiency. The dimensions, precision, range of motor travel and load bearing of the positioner are all customizable.

4.EPP High Performance Absorbers
The EPP absorbing material is developed, manufactured and tested by GTS. It uses environmentally friendly and durable EPP(Expanded Polypropylene) as base material. Through full-wave simulation and optimization design, it ensures the overall absorbing performance of the absorbers. The absorption rate testing technology with ultra-wideband, multi-angle incidence guarantees the excellent quality of each piece of absorber. Its flame resistance meets UL94 HF-1 standards, with internationally leading absorption performance. The EPP absorber is dust-free, and moisture-free, it applies
to various environments, such as outdoors, clean room, PIM chamber, OTA chamber, etc.
5.Thermal Testing Module
RP1200 series can be equipped with a thermal-insulation wave-transparent ball mask, enabling high-low temperature shock and cyclic testing from -10~55 ℃. The ball mask is compatible with existing positioners, requiring minimal system upgrades. It can be easily installed and removed without affecting the original testing functionality.
