Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4809A #9090754 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4809A is a type of electronic test equipment, specifically known as a Network Analyzer Equipment. It is designed to measure and analyze the network performance of electrical and radio frequency (RF) transmission systems. It is utilized by engineers to evaluate the electrical characteristics of their designs, such as signal strength, frequency, noise, and impedance. HP E4809A is an S-parameter test system, which means it measures the electrical characteristics of radio-frequency transmission systems using four ratios known as S-parameters. These ratios indicate the ratio of power sent from the input port of the test unit to the power arriving at the output port. Working with S-parameters makes it easier to understand the behavior and performance of complex network structures that may contain many different active and passive elements. AGILENT E4809A can measure a frequency range between 9 kHz and 8.5 GHz. It is equipped with a band-limited vector voltmeter that can measure the amplitude and phase of input or output signals over a wide frequency range. This feature is commonly used to evaluate the frequency-domain responses of a device. The unit's frequency response analyzer (FRA) can evaluate amplifiers, filters, mixers, and other network components for more detailed observations. Additionally, its dual signal generators allow users to stimulate the device under test and set conditions for a variety of test scenarios. HEWLETT-PACKARD E4809A includes a built-in termination machine that can generate and control transmission line and short-circuiting terminations, allowing users to test devices such as high-impedance directly, without additional external termination components. The built-in dual-polarization switch helps users to quickly switch between measuring forward and reverse signals without manual intervention. E4809A is equipped with a HyperTheta Spectrum Analyzer that focuses on wideband signals, allowing users to analyze their device's wider frequency and noise characteristics. It features software such as the HEO Dynamics Pro software, which helps users configure the instrument, optimize models, and evaluate device behavior. It provides a real-time display of the results, with a customizable interface. It also includes the HyperView6 software that supports different formats and data types for post-processing capabilities. In conclusion, KEYSIGHT E4809A Network Analyzer Tool is an invaluable tool for electronic engineers, enabling them to accurately measure and analyze the performance of electrical and RF transmission systems. It is designed to accurately measure frequencies and noise levels, as well as S-parameters to evaluate complex networks. Additionally, it is equipped with two signal generators, a built-in termination asset, and various software packages that make it a highly effective and easy-to-use tool.
