Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4285A #9001622 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4285A is an electronic test equipment that offers a wide range of features for both research-level and industrial-level applications. It is a precision LCR meter with capabilities for making - rapid, precise, and repeatable - measurements of electrical components and circuits. With a range of more than 1000:1, it can measure very small capacitance values with very high accuracy (down to single-digit picofarad resolutions). 8 measurement parameters can be measured on HP 4285A, such as inductance, capacitance, resistance, impedance, gain, Q-factor, dissipation, and phase. AGILENT 4285A offers two main measurement modes - series (Z) and parallel (Y). The series mode measures impedance elements or interconnected impedances serially, while the parallel mode measures the inductive, capacitive, and resistive elements of the circuit. For the series mode, there are 4 test frequencies - 1 kHz, 100 Hz, 120 Hz, and 10 kHz, thus enabling detailed analysis of the components in the circuit. On the other hand, for the parallel mode, there are 10 test frequencies for more complex measurement applications. It also features a range of digital filters that can be applied for filtering out the noise to obtain better accuracy of the measured values. With its powerful FFT (Fast Fourier Transform) capability, a wide range of signals can be analyzed. KEYSIGHT 4285A also features automated testing capability where the user can program it to cycle through different test frequencies or input levels, capturing the measured values and plotting the results on graphs. This eliminates the need for manual input of the measured values. It also offers remote operation capability via its GPIB (General-Purpose Interface Bus) interface, allowing it to be controlled by a host computer for advanced automated test applications. In addition to the automated test capabilities, HEWLETT-PACKARD 4285A has a host of other features such as a large color LCD display, a numeric keypad, context-sensitive help menus, and an extensive built-in library of measurement functions. Furthermore, its remote operation and programming capabilities are impressive, allowing a wide range of applications in research, development, and industrial environments. Overall, HP/4285A is an excellent tool for making precise measurements of electrical components and circuits; it is ideal for research and development environments, as well as for industrial settings. With its automated test, remote operation, and extensive library of built-in functions, it is one of the best tools available for measuring and analyzing electrical components and circuits.
