Create 3GPP LTE TDD test waveforms with ease

The N7625B Signal Studio for 3GPP LTE TDD is a powerful software tool that simplifies the creation of standards-based LTE and LTE-Advanced signals compliant with the 3GPP Release 9 June 2010 and December 2010 Release 10. The waveform playback mode of the software creates physical layer and transport channel coded arbitrary waveform files. These waveforms are used for measuring EVM, ACLR, and CCDF for power amplifier testing and for measuring HARQ functionality and block error rate (BLER) with standard compliant E-TM and FRC, or user-definable custom configurations Real-Time LTE TDD signal creation with PXB

The software also creates real-time uplink LTE TDD signals when used with the N5106A PXB. Real-time HARQ (Hybrid Automatic Repeat Request) and timing adjustment feedback from the eNB are used to create LTE TDD signals with dynamically changing characteristics to enable testing of receiver characteristics Signal Studio supports multiple platforms

• The MXG vector signal generators offer the industry-best adjacent-channel leakage ratio (ACLR) performance and switching speeds making it ideal for the characterization and evaluation of eNB components like multi-carrier power amplifiers.
• The ESG vector signal generators provide lower phase noise, excellent level accuracy, fading capabilities, and digital I/Q inputs and outputs making it better suited for early receiver test and UE component test.
• The PXB baseband generator and channel emulators deliver the most current, versatile signal creation and channel emulation capabilities for up to 4x2 MIMO test.
• The Logic Analyzers provide digital I/Q outputs, making it better suited for UE baseband IC and component transmitter and receiver test.
• The RDX DigRF excerciser/analyzer modules provide DigRF connectivity making it better suited for UE baseband IC and RFIC transmitter/receiver test
