Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8481H #293821630 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8481H is an electronic test equipment designed for high frequency measurements. It is a three-input mixer capable of measuring signals up to 26.5 GHz. It utilizes technology from the original 8481A, which has been redesigned for superior performance and reliability. HP 8481H consists of three main components: a mixer module, a power amplifier module, and a synthesizer module. The mixer module uses a double-balanced diode circuit to provide excellent conversion with low noise, while the power amplifier module provides the gain needed for high frequency measurements. The synthesizer module provides the signal sources for the mixer. AGILENT 8481H can measure power levels ranging from -70 to +20dBm. It utilizes two frequency mixing ports to expand the dynamic range, and a third input is provided for amplitude calibration. KEYSIGHT 8481H also features a built-in DC bias circuit, which can be set to off or on for increased accuracy. HEWLETT-PACKARD 8481H is designed to be user friendly, featuring a six digit LCD display. The user can control the unit's settings through the front panel knobs, or by connecting an external computer for data storage and manipulation. 8481H is powered either by the internal battery, or through the included AC power adapter. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8481H measures high frequency signals in a number of ways. It can measure the power of a signal, and can display the signal's distortion or noise figure to provide information on the signal's quality. It can also measure the relative level of a specific frequency, and is useful for bandpass or selectivity measurements. HP 8481H is built for durability and longevity, and is designed to last for years to come with minimal upkeep. Its waterproof and dustproof design protect it from the elements, and the unit has internal shielding to protect it from external interference. These features enable it to withstand even the harshest environments. Overall, AGILENT 8481H is an efficient and reliable electronic test equipment for high frequency measurements. Its three-input mixer allows it to measure power levels up to 26.5 GHz, while its built-in protections and durable construction make it suitable for both indoor and outdoor environments. In addition, the unit's user-friendly design and easy-to-use interface make it ideal for both beginners and more experienced engineers alike.
