The Keysight E4428C ESG Analog Signal Generator features superior level accuracy, high output power, high-stability timebase and built-in function generator
The E4428C Keysight ESG Analog Signal Generator may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
2 MHz to 6 GHz analog RF signal generator providing precision carrier frequency and amplitude, AM/FM/FM/pulse modulations, analog and digital I/Q modulation, internal dual arbitrary waveform generator, low phase noise, and high output power. Supports precise testing of receivers, components, and subsystems in wireless communication equipment, aerospace/defense systems, and general-purpose RF electronics. Interfaces via GPIB, LAN, and USB with comprehensive remote programming capabilities. Features calibrated power sweep, ramp sweep, step sweep, and list mode operations.
Platforms
Operates on Keysight RF signal generation technology platform, compatible with Windows-based control software and PC connectivity via GPIB, LAN, and USB interfaces. Supports easy integration with external test systems and instruments through SCPI and IVI command sets.
Applications
Calibration and characterization of RF/microwave components including amplifiers, filters, mixers, and antennas. Receiver sensitivity and selectivity testing. Stimulus generation for radar, electronic warfare, and communication system development. Local oscillator substitution. Carrier generation for analog modulation research and development. EMC/EMI interference simulation. General purpose benchtop RF signal sourcing for laboratory and production test environments.
Accessories
Requires an external 50 O RF load or test device for output; standard rear panel interfaces include a Type N female RF output connector, a GPIB (IEEE-488) interface for automation, and an RS-232 serial port for remote control; requires a compatible power cable per regional standards; no dedicated mainframe, backplane, or chassis is needed as it is a standalone benchtop instrument.
Specifications
Microwave frequency signal generator producing continuous wave or modulated outputs. Generates RF carrier signals from 250 kHz to 3 GHz with optional extension to 6 GHz. Features AM, FM, phase, and pulse modulation capabilities with high spectral purity. Provides precise power level control from -136 dBm to +13 dBm with optional step attenuator. Includes GPIB and RS-232 interfaces for remote operation. Commonly used for receiver testing, component characterization, and as a local oscillator substitute in RF/microwave test systems. Offers programmable sweep functions and custom waveform generation with optional capabilities for analog and digital modulation formats.
