The 5G base station check answer delivers ACLR and EVM measurements for cost-effective OTA testing of 5G community infrastructure

A brand new high-performance 5G base station check answer has been launched that allows community tools producers (NEMs) and small cell distributors to speed up validation of mmWave merchandise in line with the newest 3GPP specs.

Primarily based on Keysight’s S9130A 5G Efficiency Multi-Band Vector Transceiver (VXT), the check answer permits cell operators deploying 5G new radio (NR) in frequency vary 2 (FR2) to ship enhanced cell broadband (eMBB) connectivity in metropolitan areas and indoor environments comparable to stadiums and airports. Speedy deployment of a heterogenous community, consisting of macro base stations, small cell infrastructure, radio items (RUs) and distributed antenna techniques (DAS), depends upon streamlined testing throughout the workflow.

“Keysight’s new 5G base station check answer permits NEMs to validate 5G excessive efficiency macro base stations in manufacturing and distributors of 5G small cells to validate mmWave merchandise in R&D and design validation,” stated Giampaolo Tardioli, vice chairman and normal Supervisor for Keysight’s community entry group. “The answer combines the brand new 5G efficiency multi-band VXT with Keysight’s inner widespread interface unit (CIU) and mmWave distant radio head (RRH) to ship excessive efficiency over-the-air (OTA) testing in a compact type issue.”

Dependable Measurements

Keysight’s excessive efficiency 5G base station check answer leverages the corporate’s new PXIe based mostly vector transceiver (VXT) for delivering adjoining channel leakage ratio (ACLR) and error vector magnitude (EVM) measurements. The superior efficiency of the following era VXT and RRH brings the measurement airplane nearer to the gadget beneath check (DUT). Which means that the DUT can obtain excessive energy ranges throughout a large dynamic energy vary, leading to exceedingly correct and dependable measurement outcomes.

Keysight’s S9100 suite of options helps a number of channels for testing a number of base stations in parallel and leverage the corporate’s cloud-ready suite of PathWave software program options to simplify and velocity testing as distributors scale from design validation to quantity check. Supported PathWave options embody:

  • X-Collection Measurement Purposes for fundamental measurements comparable to EVM and ACLR.
  • 5G NR Sign Creation and Playback for characterizing energy and modulation efficiency of parts and transmitters.
  • 89600 Vector Sign Evaluation for superior demodulation and vector sign evaluation.
