Programmable RF Attenuator Matrix

HBTE MIMO OTA test system provides a flexible, fast and efficient end-to-end testing system which supporting CBRS 5G NR FR2 technology in a RF anechoic chamber. It can effectively evaluate DUT wireless communication performance, this system could achieve the test scenario of InO CDL-A~E and UMi CDL-A~E in 3GPP 38827.

Programmable RF Attenuator Matrix
HBTE carries a wide range of programmable RF step attenuator with a broad selection of attenuation levels, frequency ranges and power dissipation ranges. A programmable digital attenuator can control the attenuation of the signal and adjust the signal energy value of different channels. When you are doing some tests like base station tests, UE tests, WiFi tests, etc, you can choose HBTE RF digital attenuator to simulate the strength of the signal energy. We also provide other quality products for customers, such as fixed RF attenuator, high power RF attenuator and RF power attenuator.

Key Features of Programmable RF Attenuators
Antenna Attenuator has a compact structure, small space occupation.

Support local manual control, configuration and view device status.

Support remote control, flexibly configure an IP address, adapt to any laboratory network environment.

Multi-in-one network port, to achieve device control, firmware upgrade, remote debug, one key remote device restart.

Support multi-user control and support user permission settings.

With standard API interface, wifi attenuators support through Telnet, Python, SCPI protocol control device, to meet the needs of user automation testing.

Completely independent RF attenuation channels and the energy of each signal is adjusted separately.

Adopt solid-state device with good continuity, repeatability, and reliability, support 7*24H uninterrupted operation.
