“The enhancements to the Keysight VoLTE test solution further simplify user-experience while expanding capabilities to ensure designs meet optimal key performance criteria well before they go to market,” said Satish Dhanasekaran, general manager of Keysight’s Wireless Devices and Operator Segment.

Keysight has updated the E6966B software, which emulates the P-CSCF and IMS core network, with many new features, including the new EVS option E6966B-5TP.

The E6966B IMS-SIP network emulator software includes the client and server, enabling the user to test either in a PC-only soft client configuration, or integrated with the Keysight E7515A UXM wireless test set to emulate the entire IMS/VoLTE environment for end-to-end IMS/VoLTE test.

Complementing the UXM wireless test set and E6966B IMS-SIP network emulator software, the Keysight U8903B performance audio analyzer provides pre-configured perceptual evaluation of speech quality (PESQ) and perceptual objective listening quality assessment (PoLQA) audio measurement analysis to complete the voice quality test solution.
