Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A #18756 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A is an RF impedance network analyzer that provides high accuracy and repeatability combined with direct, user-friendly operation. It features a wide frequency range of 50 kHz to 1.5 GHz, making it suitable for a variety of applications including testing high-frequency components, measuring impedance characteristics, and developing impedance matching networks. HP 4291A consists of a main unit and a controller connected by a secure sideband frequency interface.The main unit has two ports, Port 1 and Port 2, which are used to connect to the device under test (DUT). It performs input impedance and S-parameter measurements, which can be calculated from the S11 and S22 parameters. It is capable of measuring up to 70 separate frequency points and each point can be set to a unique power level. AGILENT 4291A also includes a number of automated functions such as programmable amplitude sweep, frequency sweep, and Z-plane sweeps. KEYSIGHT 4291A also offers a wide dynamic range and low noise floor, allowing it to capture small signal variations. It has an internal pre-amplifier, which amplifies signals at low levels and a high selectivity with adjustable thresholds. It comes with a choice of software packages including HP 431XA, allowing the user to program the analyzer and remote control the analyzer. 4291A is also equipped with a USB port for transferring data to and from a PC. For calibration, HEWLETT-PACKARD 4291A offers an optional internal calibration kit and an external calibration source. The internal calibration kit can be used to calculate the accuracy of the instrument and adjust for any drift or offsets. The external calibration source is used for verifying the accuracy of the measurement. In summary, AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4291A is an accurate and reliable impedance network analyzer that is well suited for a variety of applications. It provides a wide frequency range, high selectivity, low noise floor and programmable functions, making it ideal for testing high-frequency components, measuring impedance characteristics, and developing impedance matching networks.
