Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A #177704 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A is an electronic test equipment which offers a broad range of features that enables network and impedance analysis, measurements of small to medium networks, and RF matching networks. Specifically, HP 4291A is a broadband Impedance analyzer designed for a wide range of frequency range from 20 Hz to 500 MHz for a variety of one, two or four-port measurements, such as 24 different S-parameters, admittance, admittance, dissipation factor, inductance, capacitance, and other impedance parameters. Additionally, the analyzer allows an external reference calibration that conforms to IEEE 442 standards. The main body of AGILENT 4291A is composed of two parts: the controller and the Bridge, which is connected through a five-meter cable. The Bridge includes the direct-through method and the short-open-load method. The analyzer is powered with AC mains and the controller is connected to the host computer with a USB port. 4291A has an intuitive user interface, designed to easily control the processes of setting, measuring and saving capable of displaying the results in a variety of formats. The user can directly set up the analyzer's parameters through the control panel, including trigger levels, filter modes and order, input range, frequencies, and plot type, etc. It also provides a readout of measured impedance value which can be observed on the display panel at the same time the plot is being generated or saved. KEYSIGHT 4291A supports two different calibration techniques: open-short-load and the direct-through. It can automatically switch from one mode to the other depending on the impedance values to be measured. Its accuracy is traceable to international standards of measurements and is higher in the deployed condition. Moreover, it allows the built-in wide bandwidth testing resolution. Such feature enables the user to test components with higher accuracy and reliability by continuously measuring the same frequency with different bandwidths. In addition, HEWLETT-PACKARD 4291A offers several test routines that optimize the testing of matching networks and RF components with multiple impedances and aircraft systems. Also, by creating a Gold standard calibration system this electronic test equipment ensures more accuracy and repeatability of measurements. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A is ideal for industrial, product development and R&D applications, such as matching networks and filter design and testing, as well as biomedical and electrical engineering departments that require accurate and reliable results.
