Easy, low-cost and space-saving 5G NR fading tests now possible with a single Radio Communication Test Station unit.

Anritsu has announced the launch of its popular Radio Communication Test Station MT8000A with upgraded 5G Protocol Test functions. The upgrade uses NR (New Radio) fading software when implementing built-in baseband fading tests, making the MT8000A capable of providing support for 3GPP TS 38.521-4 B.1/B.2 V15.0.0-compliant 5G NR channel (TDL) model tests.

A fading test simulates the actual radio-wave propagation environment and is required for development of mobile devices. Previously, an external 5G RF fading simulator was required, but this is now implemented as an internal fader in the MT8000A, supporting either 2CC 4x4 MIMO tests with one MT8000A unit, or 8CC 2x2 MIMO tests with two units.

As a result, Protocol Test set-up in a fading environment is simpler and elimination of external test equipment, as well as compatibility with existing protocol functions, helps cut development costs.

Mobile-terminal development requires 3GPP-compliant testing and evaluation to assure interoperability. These tests are not limited to static communications protocols and RF evaluations between mobiles and base stations, but also include Radio Resource Management (RRM) tests simulating a moving mobile unit, as well as evaluations, in a fading environment.

The MT8000A is for mobile-terminal vendors requiring efficient tests with good cost-performance covering a wide range of conditions. It is an all-in-one test platform for RF, protocol and beam tests, as well as for beam-forming evaluations. In addition to supporting functions for simulating base-station NSA and SA modes required for development of 5G chipsets and terminals, it also supports the latest technologies, such as 4x4 MIMO for increasing data transmission speeds in the sub-6 GHz band, as well as 8CC for implementing wideband mmWave.

The MT8000A covers the key frequency bands used by the first 5G services, such as the sub-6 GHz band (FR1) frequencies of 2.5 GHz, 3.5 GHz, 4.5 GHz, etc, as well as the mmWave band (FR2) frequencies of 28 GHz, 39 GHz, etc.

The easy-to-use interface coupled with comprehensive RF measurement and NR fading software makes it easy to configure a reasonably priced cost-effective test environment.
