AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4990A is a versatile, high-performance electronic test equipment designed to provide accurate and reliable measurements and analysis. It is a source impedance analyzer that is capable of performing various types of impedance measurements and other electrical measurements. HP E4990A is a network analyzer that features two channels of full cross-channel scalability, allowing users to measure and analyze the impedance of a device under test from multiple perspectives and frequencies. The analyzer also features a wide bandwidth of up to 6 GHz, enabling users to make accurate and repeatable assessments. AGILENT E4990A makes use of six software modules to enable users to customize their measurements and analysis to fit their needs. These modules are the Scalar, Impedance, Pulse Response, DAC/Source, Synthesizer, and Digital converter modules. The scalar module allows users to measure the scalar parameters of a device under test, such as its dc resistance and capacitance. The Impedance module is designed to measure both ac and dc impedance of a device. The Pulse Response module allows users to measure and analyze the pulse response of a device, while the DAC/Source module enables users to produce precise and repeatable waveforms from within the module. The Synthesizer module can produce multiple types of signals, including sine, triangle, and square waves. Lastly, the Digital converter module can be used to convert digital signals into their analog counterparts, making calculations much simpler. HEWLETT-PACKARD E4990A also offers a variety of interface capabilities, including a 10-pin IO port, a GPIB port, a USB port, and a LAN port. As such, users can connect the analyzer to an external computer and program their tests from there. Overall, E4990A is a top-of-the-line, high-performance source impedance analyzer. Its powerful modular design coupled with its wide bandwidth and comprehensive interface capabilities make it a great choice for anyone who needs to make precise and reliable impedance measurements and analyses.
