Keysight N7624B Signal Studio for LTE/LTE-Advanced FDD is a PC-based signal creation software application designed to generate standard-compliant LTE and LTE-Advanced FDD waveforms. It supports both uplink and downlink testing, offering waveform playback (ARB) and real-time generation modes. The software connects directly to Keysight vector signal generators and wireless test sets via LAN, GPIB, or USB interfaces to facilitate comprehensive receiver and component testing.
