The U7227A, 10 MHz to 4 GHz USB preamplifier is designed to bring reliable gain and low noise figure to measurement systems improving the overall system performance and reduce systematic errors; a total solution to the X-Series signal analyzers to perform noise figure measurements.
When connected to the X-Series signal analyzers, the USB preamplifiers can automatically configure the analyzers to detect the specific preamplifier connected, and download the embedded calibration data such as gain, noise figure and S-parameters. The calibration data provides accurate correction data and more repeatable results for each actual measurement made.
Key Features:
- Automatic temperature-compensated gain corrections and calibration data transfer (noise figure and S-parameters) through USB plug-and-play improve noise figure measurements with Keysight X-Series signal analyzers
- Excellent noise figure and optimized gain with the X-Series signal analyzers improves measurement accuracy and minimizes uncertainty
- Provides broadband operating frequency from 10 MHz up to 4 GHz for various applications
- Rugged and portable design for bench top measurements or remote front end field applications
