Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991A #9127108 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991A is an electronic test equipment designed for a wide range of test and measurement applications, such as impedance, capacitance, and reactance measurements. It is ideal for characterizing a large range of electronic components such as capacitors, resistors, inductors, and transmission lines. HP E4991A is a single instrument with two ports consisting of a mix of SCPI-RF wide bandwidth (up to 50 MHz) and ENA series high-impedance, low-distortion Vector Network Analyzer (VNA) technology. This makes it ideal for exacting, precise measurement of impedance, scattering, S-parameter, or TDR (time domain reflectometry) applications. AGILENT E4991A is a high-performance, two-port vector network analyzer. It has analyser bandwidths up to 50 MHz, making it ideal for precise impedance, scattering, and S-parameter measurements. It can measure the impedance, resistance, inductance, reactance, capacitance, and phase variation of any passive component over a wide range of frequencies in the 200 kHz to 50 MHz range. Its multi-functional measurement provides accurate characterization by providing a set of nine test functions, such as impedance, S-parameter, admittance magnitude and phase, return loss, insertion loss, directivity, and phase. E4991A features a full range of functions, including frequency response plot (FRP), logarithmic (dB) plane plot, Smith chart plot, and stability factor testing. HEWLETT-PACKARD E4991A also features a wide range of measurement applications, such as matching impedance device measurements, impedance bridge measurements, resonator measurements, and differential S-parameters. It includes built-in calibration and automated control of calibration standards, making it easier to use and more reliable. There is also an internal adjustable power supply for controlling internal device bias voltage. KEYSIGHT E4991A is designed for a wide range of markets such as research and development, manufacturing, repair and troubleshooting, and procedure validations. It is a valuable tool within the design, fabrication, and repair and calibration departments. It can be used for a variety of applications, such as measuring the characteristic impedance of EVC cables (Ethernet crossover cables) and antenna impedance of cellular phone antennas. It is also used for testing network devices, verifying the observance of network standards, analyzing filters, and troubleshooting the signal integrity of interconnects and networks. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4991A vector network analyzer is the perfect tool for demanding and precise characterization and verification tests in electronic applications. Its high accuracy and wide range of capability makes it an invaluable tool for laboratory and production requirements.
