Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991B #9276496 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991B is a high-performance two-port network analyzer designed for microwave and RF measurements. It provides the capability to characterize and measure the response of complex microwave and RF devices, amplifiers, filters, mixers and other components. HP E4991B is a full 2-port vector network analyzer offering a wide frequency range from 5 kHz to 110 GHz. It can measure up to 4 S-parameters over a full 2-port calibration plane. It can also measure and characterize both magnitude and phase information with the differential and isolation tests that are available in this model. The data is highly accurate due to an internal low-noise source and highly stable internal RF measurement channels. AGILENT E4991B has a high dynamic range up to 60 dB and provides full 2-port calibration with 30 short and open standards eliminating the need for external high-power test ports. It also has low-noise measurements (reflection coefficient < -100 dB, transmission coefficient < -105 dB) as well as excellent phase accuracy using its unique calibration method. It is compatible with many other measurement systems and can be used in stand-alone, LAN, GPIB, or USB applications. E4991B offers excellent measurement speed and flexibility, allowing users to choose from a wide variety of connector, frequency, and power settings. It has a performance optimization feature which allows operators to design devices more quickly using fewer test steps. It also offers multiple hardware levels allowing you to make the most of your equipment investment. HEWLETT-PACKARD E4991B also has a wide variety of built-in test plans which allow users to perform a variety of measurements including antenna alignment, multi-port impedance, wideband measurements, gain compression analysis, gain ripple accuracy, magnitude imbalance, phase variation, small-signal gain flatness, harmonic distortion, channel-isolation, fade margin, multi-tone analysis, and signal-level measurements. In summary, KEYSIGHT E4991B two-port network analyzer is an ideal tool for RF and microwave device characterization and RF impedance measurements. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991B offers excellent performance, low noise, flexible calibration, and fast data acquisition in order to accomplish complex measurements quickly and accurately.
