The MG3700A Vector Signal Generator has a built-in, high-speed, arbitrary waveform baseband generator with a 160 MHz sampling rate. It supports a vector modulation bandwidth up to 120 MHz, has a large arbitrary waveform memory up to 2 GB, and outputs digital modulation signals for major mobile communications, including LTE FDD, LTE TDD, Mobile WiMAX, digital broadcasting ISDB-T/ISDB-Tmm, wireless LAN, GPS, etc. IQproducer is a PC software application for generating waveform patterns for the MG3700A. It has a parameter setting screen for each communication method, including LTE FDD, LTE TDD (TD-LTE) and Mobile, enabling users to set parameters for generating any waveform pattern. Transfer of generated waveform patterns to the MG3700A supports modulated signal output. In addition, IQproducer can convert ASCII files generated using EDA (Electronic Design Automation) tools (MATLAB etc.) to waveform files, supporting unique modulated signal measurements.
