Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4990A #9248547 for sale

HP/AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4990A is an advanced full impedance, precision network analyzer with a frequency range of 1 MHz to 1 GHz. This electronic test equipment is designed to ensure accurate results for measuring complex impedance structures. Its flexibility facilitates the measurement of both single-ended and differential devices, allowing users to gain a better understanding of how their designs work. HP E4990A's advanced design features a digital signal processor for high speed and accuracy, and a powerful real-time operating system for versatile control. This allows users to capture wide dynamic range S-parameters and obtain quick results in a variety of testing environments. AGILENT E4990A has four measurement modes: Auto-Calibration, Full Measurement Power, Two-Port, and Power Sweep. In Auto-Calibration mode, the analyzer will automatically adjust the reference plane offset and instrument match before starting the measurement. The Full Measurement Power mode allows the analyzer to acquire maximum power measurements, while the Two-Port measurement mode allows the user to examine devices with multiple ports. Finally, the Power Sweep mode allows the user to measure the total power dissipated by a device at different frequencies. The analyzer's frequency characteristics include Low Frequency Contact Compensation (LFCC) and High Frequency Contact Compensation (HFCC). LFCC reduces errors caused by contacting artifacts at low frequencies, and HFCC compensates for errors caused by skin depth and other high frequency effects. KEYSIGHT E4990A also features automatic display stacking, which allows users to quickly view and compare multiple measurements on a single graph. This can be used to measure complex impedance structures, identify small changes, or to better understand the full performance of their designs. Finally, the analyzer has an intuitive control panel and two large displays with full auto-correlation and SDE functions that allow for fast setup and one-touch operation. It also includes plenty of helpful features such as an application selector for quickly selecting the best measurement mode, a quick link function to access frequently-used settings, and LAN/USB/GPIB interface to connect with other test instruments. HEWLETT-PACKARD E4990A is a highly versatile, professional-grade analyzer that provides an accurate and reliable measurement solution for a wide range of applications. It has a well-rounded design which allows users to easily and quickly measure all their designs with precision.
