Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657A #9220813 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657A is an electronic test equipment used to measure and generate RF signals. It is equipped with two receivers and two internal synthesizers. As part of HP microwaves family, HP 8657A has a frequency coverage from 100 kHz to 2.1 GHz and wide-dynamic range measurements that can be achieved with very low phase noise. It is equipped with an hybrid automatic leveling (HAL) circuit, low noise squaring detectors, and frequency counter which provides accurate measurement and signal factors for radio frequency (RF) instrument users. AGILENT 8657A offers wide dynamic range up to +25 dBm, DC bias control up to ±2.2 V, and high-speed AC coupling control up to 1 MHz. This RF test equipment has several features including high accuracy measurements, with low harmonic distortion, low noise figure and high 2-tone IMD rejection. It also has built in data cycle and sweep control to simplify measurement set up. The internal synthesizers have very low phase noise and provide the frequency range from 10 kHz to 2.1 GHz and below. For measurement and generation, HEWLETT-PACKARD 8657A can be connected to an external signal source or connected to external monitoring hardware. KEYSIGHT 8657A features programmable energy detection limits and tone spectrum display to enable users to measure various parameters of the signal, including power spectral density, uplink power to the satellite receiver, two way impedance and gain flatness. 8657A instrument includes both touch screen and manual control operation, data storage from 8 MB embedded memory, and connection with a remote PC. It also has an optional high speed testing card with 1 MS/s sampling rate, 12-bit resolution, and 16-bit wiley-trueness for accurate measurements in signal analysis and debugging. Additionally, the instrument permits an optional LAN connection that is used for remote control and data recording. Overall, AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657A is a robust and high-performance RF and microwave test instrument commonly used for RF engineering and development, especially in aerospace, defense, and communications applications. It features wide frequency coverage, high dynamic range and low phase noise for fast and accurate measurements.
