Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4284A #293636853 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4284A is a precision LCR meter used for measuring inductance, capacitance, and resistance. This versatile instrument is capable of measuring component parameters with extreme accuracy, making it an ideal choice for general-purpose component testing applications. HP 4284A provides six impedance measurement frequencies of 100Hz, 120Hz, 1kHz, 10kHz, 100kHz, and 1MHz. It can measure inductance values from 1µH up to 10H, capacitance values from 980µF down to 1pF, and resistance values down to 10mΩ. The unit's user interface is intuitive, with menu-driven operation and dedicated keys for setting the source value, measurement speed, measurement functions, and other parameters. A full numerical display is provided, making measurements quicker and easier to read. A wide range of test conditions for a variety of measurements can be programmed using AGILENT 4284A's graphical user interface. HEWLETT-PACKARD 4284A features nine discrete test parameters for capacitive, inductive, and resistive measurements. The user can select from various measurement functions, such as equivalent series resistance (ESR), quality factor (Q), dissipation factor (D), and phase angle (θ). The unit has two power Line Inputs, a 0V to 30V general purpose output, a 25A general purpose output, and an A/D converter for output signals. KEYSIGHT 4284A also has a USB port for connection to a PC. For electrical safety, the unit is designed with over-voltage and overcurrent protection. The meter also has a built-in noise detector and ground-current measurement function. 4284A is accurate and reliable. It has a measurement uncertainty of 0.001% at 1kHz (for 1kΩ resistance) and 0.5° at 1kHz (for 1µH inductance). The instrument can be calibrated for a range of temperatures and frequencies, allowing for high accuracy in various test conditions. It also features a long-term stability of 0.1%/year. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4284A precision LCR meter is the perfect choice for measuring inductance, capacitance, and resistance values with extreme accuracy. Its intuitive user interface, selectable test parameters, and robust features make it an ideal tool for component and device testing.
