Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4443A #9142841 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4443A is a network analyzer designed to provide measurement and analysis of electrical networks. It is an RF network analyzer with 1 or 2 ports that provides versatile, high-accuracy measurements up to 3 GHz and can measure various network configurations such as single-port, two-port, dual-selectivity, and dual-resonator configurations. HP E4443A network analyzer can measure and analyze electrical networks with greater versatility than any other RF/microwave network analyzer. With the help of the digital signal processor, it can perform signal processing of the measured frequency domain data faster and more accurately than other RF/microwave network analyzers. It uses vector network analyzer (VNA) technology, which provides an accurate calibration of the source and receivers, enabling measurements that are independent of the network's configuration. The analyzer includes a high-speed time-gate sweep that incorporates a linear phase response for accurate results, even for networks with complex frequency responses like pulse networks. It also includes a dual-sweep generator for improved signal-to-noise ratio and reduced measurement distortions which can enable measuring unknown signals or complex multipath networks. The analyzer comes with a variety of features that can enhance its versatility, such as advanced displays, advanced averaging capabilities, segmented memory, dual DUT mode, user-defined calibration standards, and user-defined reference impedances. It also includes a wide range of software options that can enhance its performance, including signal analysis, EMI/EMC analysis, channel/path responses, and frequency-response measurements. For increased accuracy, the analyzer features a noise matching system that provides the best dynamic noise cancellation and noise-free measurements. It includes fast tracking reference vector limits, which can track input parameters and detect trends or changes in the dynamic range of the test signals. It also includes enhanced noise figure measurements for accurate noise figure measurements even for low noise signals. The analyzer also includes a built-in IEEE-488.2 compatible interface for remote control. This can be used for remote monitoring, data collection, and post-processing. It also includes an internal power monitor, which can monitor the power levels and provide power accuracy comparison with a reference generator. Overall, AGILENT E4443A is a versatile and accurate network analyzer designed to measure and analyze RF networks with greater accuracy than other RF/microwave network analyzers on the market. It features comprehensive signal processing capabilities, advanced display features, and IEEE-488.2 compatible remote control compatibility, making it a powerful tool for network analysis and troubleshooting.
