Keysight E8251A Microwave Signal Generator

Overview

The Keysight E8251A is part of the Performance Signal Generator (PSG) series, designed for accurate characterization of RF and microwave products. It eliminates the need for external amplifiers in high-power device testing and provides up to +20 dBm output power with superior level accuracy of ±0.7 dB. The E8251A reduces test uncertainties and improves production throughput through excellent specifications and advanced modulation capabilities.

Key Features

• Frequency range: 250 kHz to 20 GHz with 0.01 Hz resolution
• Output power: +13/+20 dBm at 20 GHz with excellent level accuracy (±0.7 dB)
• SSB phase noise: -110 dBc/Hz at 20 kHz offset at 10 GHz carrier (standard); optional -98 dBc/Hz at 1 kHz offset
• Modulation: AM, FM, phase, and pulse modulation
• Dual internal modulation generators with sine, square, triangle, ramp, noise, and swept sine up to 1 MHz rates
• Internal pulse generator: 14 MHz max PRF
• Digital sweep functions with point-by-point calibration
• Frequency extension: up to 110 GHz with Keysight 83550 Series modules

Applications

• RF and microwave component characterization and testing
• Modulated signal generation for communication systems
• Device validation in design and manufacturing
