Description
Technologies

High reproducibility and maintainability due to full digital baseband processing
One unit supports LTE 4x2 MIMO or 2x2 MIMO 2-cell testing
Supports LTE 2x2 MIMO to W-CDMA inter-system handover tests
Easy fading settings with MD8430A/MD8480C test scenarios
Extendable hardware platform with up to four input and four output ports

The MF6900A Fading Simulator connects to the MD8430A Signalling Tester via a dedicated digital interface to easily simulate an LTE base station and run fading simulation tests required by 3GPP LTE 2x2 MIMO and 4x2 MIMO tests.

It supports all fading propagation tests defined by 3GPP TS36.521 and uses full digital baseband processing to assure fading processing with high reproducibility at the same settings, while greatly simplifying difficult MIMO power control and achieving high accuracy.

One MF6900A unit supports both LTE 2x2 MIMO 2-cell as well as 4x2 MIMO tests and combination with the MD8430A Signalling Tester with LTE support makes it easy to configure an LTE 2x2 MIMO system for handover tests. In addition, LTE/W-CDMA inter-system handover tests are supported by connection with the MD8480C Signalling Tester with W-CDMA option.
