Aeroflex Ltd has released a new software measurement suite for its PXI 3000 Series of modular instruments. The software supports the Time Division Duplex (TDD) mode of 3GPP Long Term Evolution (LTE)also known as TDD-LTE.

The LTE TDD Measurement Suite provides LTE TDD chipset, handset and terminal device manufacturers with the test capability to rapidly characterize device performance. In conjunction with PXI 3000 RF instrumentation and existing LTE FDD measurement suite, Aeroflex is now able to offer comprehensive RF parametric test capability for LTE devices operating in LTE 3GPP TDD and FDD bands.

The measurement software is able to support all uplink and downlink configurations including special sub-frame configuration as defined in 3GPP 36.211 section 4.2. LTE analysis is supported for uplink (SC-FDMA) transmissions for all bandwidths 1.4MHz to 20MHz and modulation types QPSK, QAM16 and QAM64. In addition to numerical measurement results, the software provides trace displays for spectrum emission mask, CCDF, constellation plots, EVM vs. Carrier and EVM vs. Symbol. EVM analysis for uplink signals is supported for PUSCH, SRS and PUCCH.

The PXI 3000 LTE TDD Measurement Suite has been tested and verified against the Aeroflex TM500 TD-LTE standard test mobile, reflecting Aeroflex's capability in end-to-end testing of LTE TDD from network infrastructure to user equipment. This addition of LTE TDD capability to the PXI 3000 completes Aeroflex's product offering from R&D right through verification and servicing to manufacturing.
