Description

The Agilent E4437B ESG-DP Digital RF Signal Generator is a high-performance RF signal source designed to generate accurate continuous-wave, analog-modulated and digitally modulated signals. It covers a frequency range of 250 kHz to 4 GHz and offers enhanced phase-noise performance for demanding wireless and RF testing applications. The E4437B supports AM, FM, phase modulation, pulse modulation and digital I/Q modulation, including multiple FSK, MSK, PSK and QAM formats. It provides an RF modulation bandwidth of up to 35 MHz and can be equipped with an optional dual arbitrary waveform generator or real-time I/Q baseband generator. The instrument is ideal for testing receivers, amplifiers, filters, antennas, communication modules and other RF devices. Its excellent spectral purity, flexible modulation capabilities and programmable frequency-and-power sweep functions make it suitable for telecommunications laboratories, research and development, production testing, equipment servicing and quality-control applications.
