Create LTE/LTE-Advanced waveforms for component testing

The basic waveform playback mode of N7625B Signal Studio for LTE/LTE-Advanced TDD allows you to create and customize waveforms to characterize the power and modulation performance of your components and transmitters. It provides standard compliant test models (E-TM) for measuring the EVM, ACLR, Tx ON/OFF power, and CCDF of your components and transmitters.

Create LTE signals for receiver testing

The advanced waveform playback mode allows you to create LTE waveforms with transport-channel coding to validate eNB and UE receiver characteristics and performance. It provides standard compliant fixed reference channels (FRC), or user configurable custom configurations, for performing receiver measurements such as HARQ functionality and BLER.

It also provides a real-time mode for eNB receiver testing, enabling you to create real-time uplink LTE signals for closed-loop HARQ and timing adjustment testing.
