The E6650A EXF Wireless Test Set from Keysight is a one-box tester dedicated to femtocell manufacturing. The EXF is validated with the latest WLAN and cellular chipsets, including LTE and LTE-A. Its scalable design allows up to 4 TRX per chassis to enable parallel testing of multiple femtocells. It can be used to test signals up to 6 GHz with 80/160-MHz bandwidth on each TRX. The wireless test set handles high volumes with multi-DUT testing and parallel, sequential and hybrid methods in one chassis. The quad-core controller and high-bandwidth PXIe backplane enable ultra-fast processing and data transfers.
